This might be an aid, or an annoyance. Surprise! OK, let’s try that. This is from a thin metal mask in front of the sensor. In particular, many stars look green, from the dominance of green-filtered photosites on Bayer-array sensors. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. I've tried a few at 14mm, f2.8, 20sec aa 25600iso and I got amazing pictures from it. 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. With the Canon full-frames you simply fire the shutter again. This is a Reddit's best source for talking about the Sony Alpha photography system. I have learned that night shots below 800 are noisier so for what it is worth. It’s not strictly hardware nor just software. 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. Sony’s A7III camera has enjoyed rave reviews since its introduction earlier in 2018. That was a bit surprising. At 30 fps, 4K videos are cropped with a 1.2x crop factor. It’s physics. Image quality was just fine. Forget the verbal arguments from authority — I invite you to do the experiment. Which will have the lower noise? You can push it to maybe 20 seconds if you won't be looking at it in a large size (ie. Shooting typical 400-frame time-lapses used about 40% of the battery capacity, similar to the other DSLRs. Having some investment in the Sony ecosystem (Nex 5N + various lenses), It’s an area I’d hope Sony address, and would remove an upgrade barrier for me that’s almost as significant as the start eater issue. Camera settings. As its name implies, a mirrorless camera lacks the reflex mirror of a digital single lens reflex camera that, in a DSLR, provides the light path for framing the scene though the optical viewfinder. This was true whether I was shooting compressed or uncompressed Raws, with or without Long Exposure Noise Reduction. The images shown here were shot at lower ISOs to underexposure the dark scene by 2 to 4 stops or EV. Thanks! It shouldn’t. Pixels, or photosites, do not “know” how large a sensor they belong to. 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. Full resolution examples of the “Star Eater” issue are available for download here (.zip, 8.4MB).. then, even in your case with ~3pixels wide stars, the comparison between 3.2s and 4s clearly shows a reduction of the stars “peak” brigthness, and notably less weak stars. 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. Sony doesn’t have an “a” model mirrorless. they turn off during exposures), lit buttons would be very handy at night. I’ve read so many good things about the D750 for night photography, which your review corroborated, and seen so many great images taken with it, but I have all Canon-mount lenses, which wouldn’t be compatible, so probably don’t want to go there. Or am I missing something obvious? Ie. Time-Lapse Smoothing  Features  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. Even with uncompressed Raws, the Sony was not quite as ISO invariant as the Nikon, though the difference shows up only under extreme push-processing of badly underexposed frames. Even with Canons that have a Bulb Timer for exposures >30s you can’t use it with the internal intervalometer. Indeed, the ease of manually focusing in Live View is a key function. You have ignited my fuse, thank you for that. This is most noticeable – indeed usually only noticeable – when shooting deep-sky targets though telescopes. NIKON: I deducted points for real-time video of auroras – the D750 can do them but is pretty noisy with the high ISOs needed. It showed all the same stars to the same limiting magnitude. If you wish to argue the point, do so with evidence. Custom Button 2 — Metering Mode. LENR does the dark frame taking and subtraction for you. Nikons don’t have this, not even the D810a, and not Sonys. Compact size and lighter weight, yet offering all the image quality of a full-frame DSLR. 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. While these might add glows to long exposure images, if they could be designed not to do that (i.e. This is an annoying flaw, though applying “flat fields” or ad hoc local adjustments should eliminate this. The Sony would perform better in an ISO Invariancy “face-off” if its ISOs were kept above 640, to keep all the images within the Sony’s upper ISO range of its dual-gain sensor design, with two ranges (100 to 400, and 640 on up). That’ll be a good test to make. The design lends itself to video shooting, with many mirrorless cameras offering 4K as standard, while often in DSLRs only high-end models do. I wanted to reach out to the community and see if anyone has great astrophotography settings they've used. This seems to be related to availability and quality of Sony SDKs, and is a big barrier for me. Great article. None have been tempting until the a7III came out. Custom Button 3 — Smile/Face Detect. 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. Both the Sony and Nikon use sensor and signal path designs that are “ISO invariant.” As a result, images shot underexposed at slower ISOs, then boosted in exposure later in processing look identical to properly exposed high-ISO images. As the images below show, there is a very slight one-pixel-level softening that kicks in at 4 seconds and longer but it did not eat or wipe out stars. You can take full advantage of wide-angle lenses, great for auroras. I also don’t really think I need the 42MP resolution I have with the a7RII (I thought I did, which is one reason I bought it), even though I do mostly landscapes and nightscapes. Battery Life Close. “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. Thanks again for the detailed review. Illuminated Buttons  Now I know why I haven’t seen you on my email feed in awhile! Well, almost. In the meantime, Sony commands the full-frame mirrorless market. But it is compatible with many external intervalometers and controllers. Use Compressed only if you plan to take lots of time-lapse frames and need to conserve memory card space on extended shoots. And this was with equal processing and no application of Shadow Recovery. 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). Bright Monitoring does not appear in any of the in-camera menus you can scroll through, so you won’t stumble across it. 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. Sony a6000 Moon Settings – Intro. Nevertheless, for the demands of nightscape and deep-sky shooting and processing, I suggest shooting Uncompressed Raws. Here are some other Sony a7III features I found of value for astrophotography, and for operating the camera at night. 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.”. This is a clear indication that the spatial filtering algorithm still exists. ( Log Out /  Organized Menus. Cannon doesn’t seem to be even trying to catch up. 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. While i know how to turn on LENR, does this apply only to jpegs, or to RAW shooting as well? Assign it to one of the hardware Custom C buttons. And not for filter modification. The cause is not clear. If an anti-alias filter were responsible you’d see it on all images, not just long ones. The one thing that I would like is the on camera apps that can be put on the M2 and below. But the Sony, being four years newer than the Nikon, is not better. The a6300 and a6500 cameras have an APS-C chip on board and output 24.2MP files. It controls the Sony through the camera’s Multi USB port. I may upgrade to A7SM2 and compare to A7M3. In 2018, the affordable A7iii won “Camera of the Year” at the prestigious EISA awards. Levels of luminance and chrominance noise were excellent and similar to – but surprisingly not better than – the Nikon D750. But I invite you to test your own images with various programs to see for yourself, and to not depend on second-hand reports like mine! 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.
