Coming soon, a script to reveal all details of your images.

Great shot!! :)
What's the light pollution like there if you don't mind me asking?

Deep Sky Detail (Mark) @deepskydetail.bsky.social · 24d

apps can't use all the functionality that the native app has. For example, I can't shoot in 50 megapixels using the 3rd party app, not that I'd want that for astrophotography. But it makes me wonder how much slop is being processed out with AI with the other settings that I can't access. @siril.org

If I have time and clear skies tonight, then I'll try to compare results to Samsung's camera app. Unfortunately, with the S24 (and possibly S25), you can't take true raw images using their app. It's basically a jpg in a dng wrapper. Additionally, other

...with dark and flat frames to calibrate the final image. With about one hour of exposure, I got this picture with some help from @gimpofficial.bsky.social. For bortle 5/6 skies, it's a decent #astrophotography image with a phone.

I've been experimenting with my S24 to capture the milky way. I'm skeptical of Samsung's ability to take a picture of it using its camera app. I'm just not sure how much of it is AI enhancement. So, I used a separate app with all the AI features turned off to take raw images. I stacked them in Siril

A 1 hour time lapse of the Milky Way taken with my S24 phone (raw images using the ProShot App) in Bortle 5 skies. A motion sensing flood light kept turning on, unfortunately. I think bugs were flying in front of the sensor. Processed in @siril.org with flats and darks #astrophotography #milkyway

I am an amateur astrophotographer and I'd like to contribute to the community. I also have a YouTube Channel (deepskydetail).

Why No One Agrees on Color in Astrophotography. Is Astrophotography Real Part 2: Context and Color

Deep Sky Detail (Mark) @deepskydetail.bsky.social · Sep 10

Every now and then, I see discussions about colors in astro photos. Are they real? A video I made on this a couple years ago has a surprising answer: all color everywhere is fake! It's the second video in a series. There's cognitive science to back it up! :)

I really liked the fake scientific paper I made for the intro: "Shot noise is controlled by aliens or something." :)

Deep Sky Detail (Mark) @deepskydetail.bsky.social · Sep 4

This was a fun video I made a few months back. I ran some simulations, and I showed how SNR decreases for each pixel (i.e., the signal and noise of each pixel decreases; the net effect is lower SNR).

Adding Detail by Stacking Multiple Images (Sirilic Tutoriall)

Do you want to use Siril to stack astro images, but are afraid of scripts? How about Sirilic? The latest version *mostly* works with the Beta versions of Siril. At least, it still does what I want it to do :)

Oh... and apparently, I made another video on how to process Andromeda in @siril.org and @gimpofficial.bsky.social
