Astrophotography is a hobby like any other. People enjoy capturing their own images of the universe.
Most hobbies with gear have setup costs and it's not unusual for that to be in the several thousand dollar range, and maintenance costs. $100-400/month for a hobby isn't all that much and it gives you exclusive access to your own scope in ideal skies that you can operate from your home.
I'm putting one of the modern "Smart Scopes" on my Christmas list this year.
I had a friend with a 10" Meade with which not much happened. Just a bear to lug around and set up and mess with, not even including trying bumble through getting astrophotography started.
But the new-ish Smart Scopes looks fun and accessible, so gonna see if I can get one of those to play with.
To get into Astrophotographg you probably need to spend £2-3k for some equipment, if you are based somewhere like the north of England this translates to a handful of clear nights per year. Sending your equipment here gives you an order of magnitude more clear nights.
I wouldn’t do this as I like the fact my photos are taken in my back yard but each to their own
I saw an interview with the owner, one point he brought up in addition to atmospheric clarity is that many people need a long travel time to get away from light pollution, reducing available nights even further.
It's a hobby, there doesn't need to be much in the way of novel "data" for it to be rewarding. Though considering this guy found a nebula I wouldn't be surprised if there was some. The universe is big (citation needed) and good hobbyist telescopes are quite powerful; you have a lot of sky to explore and could easily be getting the best images ever of any particular patch of it.
