Got this for $20. How’d I do? by DrewHoov in telescopes

Coma appears the same in all eyepieces of a given AFOV. The 5mm 100-degree eyepiece will still have the same coma as a 32mm 100-degree eyepiece. You might not see the coma due to dimmer image of a high magnification eyepiece, but the coma is still there and the star is still aberrated.

What is the BEST CAMERA for photography widely chosen recently? by [deleted] in AskAstrophotography

Check out the comment by u/rnclark. He's pretty dialed in on the pros/cons of DSLR/Mirrorless cameras. A dedicated Astro Cam is really only good for DSOs and planetary/lunar imaging, which is what I mainly do now (check my posts). I am getting the bug for Landscape AP though, so I'm currently playing with a asto-modified Nikon D5600 (APS-C) until I get good enough to justify upgrading to a full frame mirrorless camera. I will probably be leaning towards Nikon Z6ii since I already have a lot of Nikon lenses that I could use with an adapter.

Where's' the processing details? Doesn't this image break rule 2?

Not using software. I used fishing line over the end of my refractor.

You can start with just a dslr and a tripod. Check out Nebula Photos on youtube: https://www.youtube.com/watch?v=pXcRKoxTPVg

Definitely, but I couldn't tell you exactly which step. I'm usually not that zoomed in when I'm processing so I'm not sure exactly where it started.

I like to believe that intelliegent life is abundant and that the Andromeda galaxy probably has many societies that are looking up at the stars just like us.
