astrophotography settings a7iii

This emphasizes just how good the Nikon D750 is. But with the Nikon you would be buying all new lenses I would imagine. The settings are suitable for both the A7RIII and A9 cameras and include the following settings: Recommended shooting Mode and Aperture File Format and File Type Drive Mode, Focus Mode and […] We met this little furball on our walk. SONY: I deducted marks from the Sony a7III for deep-sky imaging for its lack of a light frame buffer, poor red sensitivity, odd LENR performance, and purple amp glow not seen on the other cameras and that dark frames did not eliminate. When using a slow shutter speed with ND filter for waterfalls on a Sony mirrorless camera, like the Sony A7riii or A7iii, don’t forget these settings: Use a tripod; ND filter attached to lens, between a 6 stop and a 10 stop filter. It works very well. 3. In a mirrorless, the camera remains in “live view” all the time, with the sensor always feeding a live image to either or both the rear LCD screen and electronic viewfinder (EVF). For astrophotography, I carry the Sony 16-35mm f/2.8 G Master, Sony 12-24mm f/4 G, the Zeiss Batis 18mm f/2.8, and now, the low light monster Sony 24mm f/1.4 G Master. When used with the Genie Mini (below) the Sony fired at only every other pulse if it was in Single shot mode, an oddity of Sony’s firmware. We're a helpful community ... let's make some art together! For nightscapes I would never shoot at a lower ISO than necessary with hopes of boosting exposure later. Astrophotography can be very rewarding when you see the end result of a great composition and exposure staring back at you through the LCD screen on your camera. However, once you get out there and break the ice, any initial confusion or intimidation will fade quickly and you’ll start getting impressive results in no time! Also the A7iii can handle higher ISO. Lenses developed natively for mirrorless models can be smaller and lighter. Raw Therapee offers a choice of de-Bayering, or “de-mosaic,” routines, and each produces different looking stars, and none look great! They do not perform differently when in a large sensor vs in a small sensor. Thanks! This might be useful for long shoots, though likely as not that same USB port will be needed for an intervalometer or motion control device. That’s why using exactly same sensor, different make and model cameras may produce diff quality images.). ISO Invariance  It is possible to power the camera though the USB port (indeed that’s how you charge the battery, as no separate battery charger is supplied as standard, a deficiency). Here are 7 astrophotography tips that have helped me capture hundreds of images of the night sky including stars, the Milky Way, Galaxies, Nebulae and more. It magnifies the Live View by 5.9x or 11.7x, allowing for precise manual focusing on a star. dark frame of the usual (for astro) exp and ISO and then in post, ramp the exposure up a few stops and the white levels up (70%) to see the consistency of the noise across the resulting image. But you can see that same effect a bit in the Nikon images, too. In Single drive mode, stars and noise soften ever so slightly at 4 seconds and higher. Noise will be higher in sensors with smaller individual pixels. Levels of luminance and chrominance noise were excellent and similar to – but surprisingly not better than – the Nikon D750. But it can take the Canon lenses you might already own. They can cost anywhere from $100 to $400. [���][deleted] 0 points1 point2 points 2 years ago (0 children). It’s all about the Focus Peaking, which I’ll get to in the camera settings below. The Sony shows a lot of green stars with or without LENR. to me, your tests are indeed showing that, even if your are not in a bad case scenario with ~3pixels wide stars, the star eater is definitely still there with all highest spatial frequencies decreased between 3.2s and 4s. At 30 fps, 4K videos are cropped with a 1.2x crop factor. Since night photography has become a bigger part of my hobby life, I’ve been considering this as a replacement for my aging a6000. Why would that be? Canon really needs to improve their sensors to keep in the game. However, like other, i must say on that the star eater is not gone on the A7s3. This is with the EVF and rear LCD Display OFF, and the camera in Airplane mode to turn off wireless functions to further conserve battery power. [���]shanew21A7Riv / @shanewarephoto 6 points7 points8 points 2 years ago (0 children), Going to be very hard to get good astro at f4, [���]Memn0na7iii, a7s 1 point2 points3 points 2 years ago* (0 children). Don’t believe me? Posting to instagram). The Sony A7III is a high-resolution full-frame mirrorless camera it can seriously compete with the best DSLRs for astrophotography and as an all-purpose camera. What we are seeing with “green” stars (in both the Sony and in the Nikon) is an effect of the de-Bayering of those cameras’ raw frames that varies considerably depending on the Raw developer you use and, in the case of Raw Therapee, the de-mosaic algorithm selected. As you surmised, the a7III is the first and only Sony mirrorless I’ve used. Exposure is set with the camera shutter speed making 30s the maximum. We will see if your theory proves correct! I researched carefully and quickly decided that a mirrorless camera was a good travel camera and a better option than a DSLR for me. The Sony will be partly incompatible with some time lapse controllers. I’ve been looking for a comprehensive review and comparison of this camera for a while now. This is because the 4 stops underexposed image was at iso 400, just under the camera’s dual gain system in the sensor. I would like to receive information about it! Due to limitations set by Sony, controlling one of their cameras with an external controller can be problematic. It’s unfair to blame just the hardware or the software. Between 2 and 4sec maybe there’s a slight softening, but there’s but no difference in limiting magnitude, unlike Ian’s test shots. To me, the star eater effect on the Sony a7III is a non-issue. LENR does the dark frame taking and subtraction for you. Sony E Mount, Sony A Mount, legacy Minolta A mount, our spiritual cousins in the RX series ... all are welcome here. Also great for sunrise/sets without a tripod ISO 50 and A f/4 still detail and super bright. Indeed, at slower ISOs and longer exposures, more stars are visible. Hurray! But the a7III should do the job for bright auroras, the ones with rapid motion worth recording with video, plus offer 24 megapixels for high-quality stills of all sky subjects. But that is true of all internal intervalometers — Pentax, Canon and Nikon. Cheers! But astrophotography, which often requires extreme contrast boosts, reveals non-uniform illumination of the sensor itself, regardless of the optics, originating from hardware elements in front of the sensor casting shadows onto the sensor. Sony’s A7III camera has enjoyed rave reviews since its introduction earlier in 2018. After reading about it myself, I tested what i’d read, and saw it to be true. “Noise” is randomness in a physical quantity, or in the method of measurement, more or less. To the eye, the Sony and Nikon look very similar for noise levels, just as in the moonlit scene. It is not clear if Sony’s compressed Raws are 12-bit vs. 14-bit for uncompressed files. However, I did not consider “star eating” to be a negative factor, as the Sony showed just as many stars and as well-resolved as did the competitors, and what more could you ask for? Best Astrophotography Settings for A7iii. The Sony would perform better for noise under dark sky conditions, at high ISOs, rather than the moonlit scene above. You have ignited my fuse, thank you for that. It may be more serious on other Sony alphas. The dark frame kicks in and locks up the camera only after the series of “light frames” are taken. Sony A7III Software. NOTE: I performed all Raw developing with Adobe Camera Raw v10.3. Which means higher iso. Otherwise, I agree with /u/RathEmpire's settings, I think you can probably go to 3200 or 6400iso if this is too dark. I’ve used this new function and it works very well. Turning on LENR did eliminate most hot pixels in long exposures, but not all. A nice in depth article that answers many questions for me. Thank you, Alan! It is good, though not great, for long-exposure deep-sky imaging. You can take full advantage of wide-angle lenses, great for auroras. Display Options The disadvantage is that full-time live view draws more power, with mirrorless cameras notorious for being battery hungry. All images are equally well exposed. • It lacks the “light-frame” buffer offered by full-frame Canons that allows shooting several frames in quick succession even with LENR turned on. A camera upgrade to a full frame is my next big purchase after I get some more experience with the T5i. Can switch between AF-S, AF-C, AF-A, DMF, or MF. At 4 seconds, some of the dimmest stars appear blurred. You mention with the a7iii that it’s not completely iso invariant and that the files when pushed 4 stops were not as clean as the shot taken at iso 6400. Set Color Space to AdobeRGB. Also missing, and present on most new Canons, are Multiple Exposure modes for in-camera stacking of exposures in a Brighten mode (for star trails) or Averaging mode (for noise smoothing). Tilting LCD Screen  I know … people shoot dark frames separately for subtracting later in processing. When comparing 1600 to 1600 from my a7ii to a7iii there isn’t much in it, 3200 vs 3200 it’s maybe half a stop – 6400 maybe 2/3 of a stop. This is excellent performance on par with the DSLRs I use. In images taken at the same time with other cameras not accused of star eating, the Sony showed just as many faint stars as the competitors. The one thing that I would like is the on camera apps that can be put on the M2 and below. And of course BackyardEOS or Nikon won’t work with Sony’s. Thanks Steve! I am a Sony A7III owner and from what I have seen using this camera for the night sky I have to agree on most of the things you said. Sony a7III, Zeiss Batis 18mm @ f/2.8, 25s, ISO 3200. And, as I found, the Sony might need to be placed into Continuous shooting mode to have the shutter fire with every trigger pulse from the motion controller. The inset image at right in Photoshop shows the scene, the Milky Way above dark trees in my backyard! The images shown here were shot at lower ISOs to underexposure the dark scene by 2 to 4 stops or EV. Great article. Worse is that long deep-sky exposures at high ISOs also exhibited a faint purple glow at the left edge, perhaps from heat from nearby electronics, a so-called “amp glow.” Or I’ve read where this is from an internal infrared source near the sensor. I have the A7S, A7RM2 and A7M3 and have been playing with the A7S since 2014, 2016 A7RM2 and 2018 A7M3 with Astro MW and other things. I currently have an a7RII but have been considering the a7III, in part because I had read some things that seemed to indicate that it had better low light noise properties. Great article, I have to note one thing though. The Sony showed poor deep-red sensitivity, though not unlike other cameras. I use a Canon T5i right now as I’m new to the craft. When using its internal intervalometer, the Nikon D750 has an excellent Exposure Smoothing option. Thank you very much for the in-depth review. The Canon 5D series also has this. USB Power  Look at the deep sky images. ( Log Out /  Light Frame Buffer in LENR I updated the firmware on my a7III. Does that mean you can’t go longer than 30s per exposure with this intervalometer (the max for bulb setting)? For astrophotography, none of those auto functions are of any value. I've watched a couple videos and there seems to be some major noise/star eater if you use any ISO over 800 (its a variable ISO in the Cameras) I'm heading to Zion National park and I'm only going to get one crack at nailing this so was hoping someone could give me some advice of successful settings they've used? Real-time video of auroras is not possible with anything like this quality with the Nikon (I’ve used it often), and absolutely not with the Canon. Not essential, but having two card slots is very helpful, for backup, for handling overflows from very long time-lapse shoots, or assigning them for stills vs. movies, or Raws vs. JPGs. The higher noise of the Canon is visually obvious, but I’d say the Sony a7III and Nikon D750 are pretty equal visually for noise, despite the numbers. For astrophotography, none of those auto functions are of any value. Rendered by PID 30836 on r2-app-0ac30b6d0efcd6480 at 2020-12-14 14:43:06.642542+00:00 running 85e58d4 country code: JP. This would explain why in your first test the +4 EV image (iso 400) and in your second test the +3 and +4 EV images (iso 200, iso 400) appear iso variant. But no more! However, I emphasize that the noise increase from using LENR with the Sony was visible only when severely boosting underexposed images in processing. I shot with the Sony a7III on Single shot drive mode, on Continuous Low drive mode (with the camera controlling the shutter speed in both cases), and a set with the Sony on Bulb and the shutter speed set by an external Vello intervalometer. In models from a similar generation it will always be the ones with the larger pixels — regardless of sensor size. “1 stop better in low light” isn’t always a flat comparison of 200 being as clean as 100, 3200 being as clean as 1600 etc. Coupled with a fast f/1.4 to f/2 lens, the slow shutter speed allows real-time aurora shooting at “only” ISO 6400 to 12,800, for quite acceptable levels of noise. I show only the Sony and Nikon compared here, shot at the common range of ISOs used for nightscape shooting, 800 to 12800. I did this testing in preparation for the new third edition of my Nightscapes and Time-Lapse eBook, which includes information on Sony mirrorless cameras, as well as many, many other updates and additions! I can assure you that even the ace programmers of Raw development software who I have spoken to are puzzled by this as well. This has been so insightful for me as an amateur. Anyway, the a7III does look compelling. I’m not here to knock Sony, in fact I shoot with one, using an A7R for my astro work because of this issue. Camera Settings 1 > Peaking Setting. I provide that evidence. Older cropped-frame cameras (Canon 7D MKII) might have worse noise because they are older and use older firmware. Using other Raw converters might affect this. In-Camera Image Stacking  And for long exposures, my 5DMkII does not offer multiple exposure feature, however, how can i take advantage of 5-frame buffer? With the Canon full-frames you simply fire the shutter again. Its extent varies from camera model to model. Aperture priority mode, selecting aperture based on desired depth of field. This movie tutorial covers the camera settings I use for capturing shallow depth of field portraits using an 85mm prime lens or Pro Zoom. Yes, and the a7III is poor in that it has the amp glow I show in the Deep-Sky images. Sony A7III | Sigma 14mm 1.8 Art | f/1.8 | ISO3200 | 20s | 10 image stack | ©Haitong Yu. You would get more stars only by going to smaller pixels perhaps, but then there’d be more noise as well partly hiding the smallest stars. Surprise! Its a pity, because if it can deliver such good results with the star-eater still present, imagine what it would deliver if Sony would only gives us a menu option to disable it. https://www.dpreview.com/forums/thread/4167521#forum-post-59686724 I am very impressed! I think any really ‘serious’ astrophotography users would be looking at a dedicated astro camera (CCD or CMOS), but know you can get some amazing results with a ‘normal’ quality camera such as those compared in this review. Take a full-frame camera and shoot a low-light, high-ISO image with it set to full-frame mode vs with it sent to take a cropped APS frame image. It shouldn’t. As versatile as a mirrorless camera is for lens choice, making use of that versatility requires buying the right lens adapter(s). Change ), You are commenting using your Google account. This is wonderful for taking a set of noise-reduced deep-sky images for later stacking. The learning curve for astrophotography and nightscape photography can be steep. None have been tempting until the a7III came out. Most tests focus on its superb auto exposure and auto focus capabilities that rival much more costly cameras, including Sony’s own a7rIII and a9. The a6300 and a6500 cameras have an APS-C chip on board and output 24.2MP files. If you wish to argue the point, do so with evidence. https://blog.kasson.com/a7riii/the-sony-a7riii-eats-stars/ This is all with Raws developed with Adobe Camera Raw. That includes simple intervalometers like the Vello, the Syrp Genie Mini panning unit, and the Dynamic Perception and Rhino sliders, to name devices I use. An issue that, to me, has a more serious effect on star quality is the propensity of the Sony, and to some extent the Nikon, to render tiny stars as brightly colored points, unrealistically so. Great review, and impressive for its detail. Hi Alan, thanks for this detailed review. Yes, this can all be done later in processing, but having the camera do the stacking can often be convenient, and great for beginners, as long as they understand what those functions do, or even that they exist! Custom Buttons  Thank you very much again! The advantage of purely electronic viewing is that the image you are previewing matches the image you’ll capture, at least for short exposures. Since publishing the first results a number of people commented with suggestions for further testing, to check claims that: For the additional tests, I shot all images within a 3-hour span on the night of June 5/6, using the Sony a7III, Nikon D750, and Canon 6D MkII, with the respective lenses: the Laowa 15mm lens at f/2, the Sigma 14mm Art at f/2, and the Rokinon 14mm SP at f/2.5. The Sony still showed some discoloration artifacts and added noise when boosting images by +4 EV that the Nikon did not. If you compare iso 640, to shots at 3-4-5 stops higher, I believe you’ll see more similar results. Only being f/4 is gonna limit you. I’m sorry, but I have to agree with John on this one: Your comparison of different exposure times *clearly* shows, that the filtering is still in effect and it wipes the smallest stars (up to 4 or 5 pixels area). The area of the sensor as a whole has nothing to do with if. Bulb Timer or Long Exposures It just needs to be better, Sony! Please have a look at them again. You’re right about the benefits being more in the shadows than the highlights though. But the Sony, being four years newer than the Nikon, is not better. This makes it so easy to frame nightscapes and deep-sky fields. Even if you could get a mirrorless camera to focus without a lens adapter to add the extra spacing, the image quality across the field might be compromised on many telescopes. Sony’s a7III camera has enjoyed rave reviews since its introduction earlier in 2018. It offers 4K (or more precisely UltraHD) video recording for videos of 3840 x 2160 pixels. The rule is max shutter speed = 500/focal length. Use Compressed only if you plan to take lots of time-lapse frames and need to conserve memory card space on extended shoots. Standard functions such as ISO and Drive Mode are easy to get at on the thumb wheel, unlike the Nikon D750 where I am forever hunting for the ISO or Focus Zoom buttons, or the Canon 6D MkII which successfully hides the Focus Zoom and Playback buttons at night. Also the best thing is ISO Invariance from 800 to 51200 with the least amount of noise for Mark 2 cameras and above. ; 1.2 Bracket Settings: -0+ order, which I find makes it much easier to group brackets when post-processing. It intrudes into the light path ever so slightly. Unfortunately, I think that you’re conclusions re star-eater are based more on hope than reality. This is much more apparent when comparing files of those ISO levels from dpreviews studio tests between the bodies. For astrophotography, none of those auto functions are of any value. Best Astrophotography Settings for A7iii (self.SonyAlpha). I think in the last few years the difference in the performance of higher end sensors have become harder to distinguish. 留99, 留7s, 留7r + Zeiss 16-35/E35/50/85/135, A7Riii | A7ii infrared mod | Minolta ���7, A7RII Batis 85 f/1.8 // A5100 50 f/1.8 // A6000 18-105 f/4, A9 | A7Riii | Sony Pro | andrewwevers.com. Hi Alan, Just wondering if you have done a test of the dark frame noise from the a7iii, or for any of your camera reviews. I had originally remarked that this useful function was missing. I did put all the high ISO images through the classic noise reduction program Noise Ninja to measure total Luminance and Chrominance noise, and included the Canon 6D MkII’s images. Thanks for doing it. You can push it to maybe 20 seconds if you won't be looking at it in a large size (ie. In your theory the image taken with it set to shoot full frame should be less noisy. I shot nothing but Raws. ; 1.2 Bracket Settings: 2 sec self-timer when coupled with Drive Mode = Continuous Bracket.. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Good luck and fingers crossed for clear skies! Sensors with 4 micron pixels will have more noise than sensors with 6 micron pixels, no matter what size the sensor is. Wait 3 years and the a7III will sell for much less. See what that gets you. Even with Canons that have a Bulb Timer for exposures >30s you can’t use it with the internal intervalometer. Again, here I show only the Sony and Nikon, the two “ISO invariant” cameras. I put it on C2, making it easy to call up when needed. Two other functions are useful for Live View: In all, the Sony provides superb, if well-hidden, Live View options that make accurately framing and focusing a nightscape or time-lapse scene a joy. This is a Reddit's best source for talking about the Sony Alpha photography system. Now I know why I haven’t seen you on my email feed in awhile! Long exposures showed just as many stars as did short exposures. Doing two shots one below for the brightness (lower ISO/higher f//slower SS or any combination) and another for the sky above (last shot) (just opposite of first) getting a combo adjustable before saving and getting a raw to work in post. Basically it’s this — “Unfortunately, Sony users are out of luck, as none of the popular control programs (AstroPhotography Tool, ImagesPlus, MaxIm DL, Nebulosity, or PRISM) support Sony cameras.”. These settings are usually set with controls on the top or back of the camera, but depending on the model or manufacturer, may be set in menus. I made that comment in the blog. This is most noticeable – indeed usually only noticeable – when shooting deep-sky targets though telescopes. The compact a7III body weighs a measured 750 grams, vs. 900 grams each for the Nikon D750 and Canon 6D MkII. I love it! In short — I found the Nikon Z6 superb for astrophotography. It is possible some of the artifacts I saw are due to ACR not handling the a7III’s .ARW files as well as it should. Stars are not smoothed out in long exposures. Maybe. Even if super dark capture knowing post will be great. Best Astrophotography Settings for A7iii. Maybe a bit noisy (hard to tell as I had a CLS filter), but still interesting to look at ^, [���][deleted] 1 point2 points3 points 2 years ago (1 child), 24mm you're gonna wanna keep shutter speed at around 15 seconds to not get visible trails. The photon “stream” already fluctuates by itself even if you have a perfect collector (which doesn’t exist, I don’t think). NIKON: I deducted points for real-time video of auroras – the D750 can do them but is pretty noisy with the high ISOs needed. Thanks! Yes, they are not as bad anymore as on earlier A7RII firmwares, which originally created all the fuzz. And the new a7sIII rumoured to come out soon would also be interesting to test. Turn on LENR and it is possible to shoot three (with the 6D MkII) or four (with the 6D) Raw images in quick succession even with LENR turned on. Contrary to expectations, the Sony did not show any great loss in image quality as it crossed the ISO 640 boundary into its lower ISO range. Sony says those buying a M3 camera are going to be pros and do not need the apps. Street Vendors at Night (A7Riv + Zeiss 55mm f/1.8), Geminids meteor shower 2020 at Alabama Hills on December 13, 2020 - Sony A7III + Sony 24mm f1.4 (IG: @kevinqlintvng), Afternoon light [Sony A7, Tamron 28-75 2.8], My first attempt at photography with a real camera Sony a6000 with Sony 18-105mm, Osaka, Japan (Sony a7rii - Zeiss 55mm f/1.8). Use the ISO that will produce a well exposed histogram for the shutter speed and aperture dictated by the scene. So I can’t compare it to the a7r or a7s models. Pixels, or photosites, do not “know” how large a sensor they belong to. One area you don’t really call out is astrophotography software support, and support by programs such as AstroPhotography Toolkit (APT) or similar (BackyardEOS/BackyardNikon, etc). And what else could you compare it to? The cameras were on a Star Adventurer Mini tracker to keep stars pinpoints, though the ground blurred in the longer exposures. For elimination of hot pixels from thermal noise I prefer to use Long Exposure Noise Reduction when possible for nightscape and deep-sky images, especially on warm summer nights. when i saw someone reporting an article that star eater was gone, i immediatly read your article. With a mirrorless camera the sensor is not set far back in a mirror box, as it is in a DSLR. I bought one and I'm truly enjoying it for night photography. Go to dpreview.com for comparison tools to allow you to judge any cameras you want on standard test charts. Iet’s say you are comparing similar size photos between sensors that have larger vs smaller pixels. These are from DPReview’s noise comparison test images. When shooting deep-sky objects, particularly red nebulas, we like a camera to have a less aggressive infrared cutoff filter, to pick up as much of the deep red Hydrogen-Alpha emission line as possible. Just info for those who have never seen the apps. You believe it will be the case, but did you know? Post was not sent - check your email addresses! I did not see any significant “star eating” in any long exposures even up to the 4 minutes I used for some deep-sky shots. Image quality was just fine. DSLR Camera Settings for Astrophotography Canon 20Da controls and settings with backlight for viewing in the dark. Having a max aperture of f/2.8 is a bit limiting when it comes to astrophotography, but you can compensate for this with a good high ISO camera like the Sony A7III. (what software subtracts such dark frames? Sony A7 III, A7R, A9 III JPG Settings There are two types of OOC JPEG settings to look at when it comes to JPG Quality on the A7 III and A9 series. Instead, I saw a slight shadowing at the top and bottom edges but just at the corners. Nor the Sony, as it has no intervalometer at all. Yes, that’s the point. It showed all the same stars to the same limiting magnitude. I just got my Sony A7III with the 24-105mm G lens. OK, let’s try that. To get the most out of the Sony for deep-sky imaging you would have to have it modified by a third-party, though the amp glow described above makes it a poor choice for modification. To my eye, the difference is nothing like the huge wiping out of stars reported and shown at Lonely Speck. Full-frame and cropped-frame cameras with similar sized pixels have similar levels of noise. Most tests focus on its superb auto exposure and auto focus capabilities that rival much more costly cameras, including Sony’s own a7rIII and a9. Though noise Itself is uniform. I may upgrade to A7SM2 and compare to A7M3. However, like other brands’ internal intervalometers Sony’s is good only for exposures up to 30 seconds long. Shooting the stars successfully requires the right camera settings along with the ability to manually focus on the stars. With the latest firmware, A7 III, A7R III and A9 all get Interval Meter built into the camera. But a monster night shooter would be the A7SM3 if left at the larger pixels of 12mm not looking forward to Video stuff (people need to get a video camera look at all the attachments anyway leave the photo cameras alone)…. Stars are visible to the same limiting magnitude and close double stars are just as well resolved across all exposures. An alternative would be an LCD screen that was touch sensitive. My Menu  This Sony lens review intends to look for what can be classed at the best lens for Sony A7iii astrophotography. Illuminated Buttons  The Sony exhibited good – though not great – “ISO invariant” performance. The correct exposure for the scene was 30 seconds at ISO 6400 and f/2. I was using the wired Vello intervalometer. But if the Sony had a built-in intervalometer…! I believe it is more likely its all about total area of the sensor and not the size of the pixels. I have a Sony A7Sii and I have not used it for a night photography or for deep sky, but I’m going to now, I’ve been away from the Hobby for a while and want to get back into the deep sky stuff. But … when well exposed, such as in tracked deep-sky images, the 6D MkII performs well. Taking a dark frame with LENR did not eliminate this, and it should, demonstrating again that for whatever reason in the a7III LENR is not as effective as it should be. Jim Kasson’s testing (https://www.dpreview.com/forums/post/61074932) provides strongly conclusive evidence that it is still present, and your first comparison shot with the Canon 6d shows small stars in the Sony that are characteristically ragged and with a dominance of green colour – exactly the features explained in Mark Shelley’s reverse engineering of Sony’s latest spatial filtering algorithm. An example is in a 4K video I shot on May 6, 2018 of an usual aurora known as “STEVE.”. Assign it to one of the hardware Custom C buttons.
