I thought I'd make a nice fun video about why it took so long for astrophotographers to notice the Oxygen Arc next to the Andromeda Galaxy. It's not too serious, and I had some fun doing it.

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.
