I think the video will be really helpful to anyone coming into the hobby. If you've been in the hobby for a while, you take for granted a lot of the terms. Like, why do you need a "main camera?" Well, because you usually have a guide camera too. I really hope this helps people get into the hobby.

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 :)

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!

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.

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.
