Deep Sky Detail (Mark)

I'm pretty impressed. I'll have a couple videos about them coming soon. One of the videos will examine 5nm bandpass filters with 12nm bandpass filters. Camera: ZWO 294MM pro, scope Orion 80mm ED doublet. It still needs more exposure time, but it's not bad :)

#astrophotography

I've been testing out some new 5nm SHO filters (fully funded by me and my YT and BMC supporters; not sent to me) on several targets. This is a test of the heart nebula (IC 1805). It's about 1.5 hours for each filter (so, about 4.5 hours total).

Until today, I thought ‘galaxies eating each other’ meant something else. 👀😬

I took these with my C8 during galaxy season a few months ago. I'm just getting to processing them because life happens and sometimes you just don't have the time. ZWO 294 MM camera with about 6 hours of L and 1.5 hours of RGB. Processed in @siril.org , @gimpofficial.bsky.social and AstroSharp.

I've zoomed in on the L filter and have included annotations for what SiriL could detect. We're looking into the deep past here. NGCs 6045 and 6047 are estimated to be about 450 million light years away. Crazy!

#astrophotography

There are a ton of galaxies in this image. In the middle are NGC 6045 and 6047. If you zoom in and look, there are edge on galaxies, interacting galaxies, merging galaxies. It's a galaxy extravaganza!

A “Great Wave” Is Crashing through the Milky Way Precise measurements of stars’ motions show that a wave is propagating outward from our galaxy’s center — perhaps from a long-ago collision with another galaxy.

I just wish I had about 4x the amount of integration time to really control the noise and the background. Next galaxy season, I'll try to get more data and combine it.

This was taken a few months ago, but I never got around to processing it because... am lazy. And I was afraid of what it would look like. At an apparent magnitude of about 12, and in Bortle 6-7 skies, it's definitely within reach for my C8.

NGC 6384 is such a beautiful galaxy, and a great example of an intermediate barred spiral. I got around 14 hours of integration time at f/10 with my Celestron C8. It's still too noisy at the edges, and definitely needs more time.

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?

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).

YouTube video by Deep Sky Detail Why No One Agrees on Color in Astrophotography. Is Astrophotography Real Part 2: Context and Color

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 dunno, I just want right and wrong to matter again.

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

YouTube video by Deep Sky Detail The Truth About Pixel Size and Shot Noise (It’s Not What You Think)

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).

YouTube video by Deep Sky Detail 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 :)
