Having been with my wife since high school, the amount of time between “no fooling around” to “where are my grandchildren” was shockingly short.

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. The cloudynights forum should If your a discord person, we do have one for this community (.gg/astrophotography) that’s pretty active with a lot of info that’s been gathered over the years, and it’s where I’ve learned most of what I know about the hobby.

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

I've finally moved away from my bortle 9 balcony! Only had one clear night so far and used it to map out my horizons, (a considerable improvement from the balcony) and spend a few hours on something bright and high up in the sky. Still got a huge ass-backlog of pics from the old place to process, but I'll chip away at that eventually. Captured on June 11th, 2026 from a Bortle 6 zone.

Upgraded to the beyond 2e from my reverb G2 and I absolutely love it! Had to go through a couple different face plates since my eyelashes were touching the lenses, but their support was really good about getting a replacement/new face scan.

Imo the weakest area is the audio strap, especially coming from the G2 which has identical speakers to the index, but in the future I’ll probably look into the project beyondex strap to get the index speakers working with it

Essentially every stacking program have options to reject outlier pixels, such as the satellites. Hell even just averaging the pixels in an image stack without the outlier rejection would greatly diminish the streaks.
