Looks great for a first shot! If you took a couple more exposures you could stack them and use dark frames to help with the hot pixels. Also if you ever get a star tracker you could stop the lens down slightly to help with the distorted stars on the edges, but overall it looks pretty decent
do you mean the edge of the frame or the edges of the stars? I’m assuming you mean edge of the frame due to the edge-to-edge sharpness diminishing wide open, but it seems to my eyes all my stars are a bit distorted – even in the center. Then again, I have no idea how they ought to look! lol. I did use the 500 rule to try to avoid star trails. I think 13s exposure was acceptable but i wanted to be safe so i went with 10s.
any chance you have any reading recommendations for astrophotography, or maybe even for astronomy in general?
Edge of the frame. Since stars are point sources of light any distortion from the optics, trailing from a long exposure, or even the atmosphere will distort them. IMO the center stars are what I’d consider acceptable for an untracked image, but then again I don’t really do much widefield astrophotography. It could also be your camera shifted slightly or from walking around near it?
There’s a number of YouTube channels of varying quality/expertise that are good for beginners, like AstroBackyard, Alaskan astro, cuiv the lazy geek to name a few.

Thanks! When you say

Ahh gotcha. I bet it was because I was wide open. I’ll check out some of those resources, thanks for the input!
