The hobby. Most of the astro sights are free to join. The forum has only really been active for a few months, but was originally set up in 2018 when I got the equipment but never did use it until this year.
For astrophotography you are easily looking at
- $800 for a beginning scope with flattener (for refractor) or about the same for a reflector with a coma corrector
- $400 for a decent guide scope and camera (or $750 for an OAG and camera)
- $1300 for a decent OSC astro specific camera and filter or two or $1800 for a decent mono camera with filters/filter wheel (or around $500 for a decent older modified DSLR with filters or $3000 for an astro specific DSLR) - upwards of $3000-$17,000 for the top end astro cameras
- $2500 for a decent mount to use with scope with for accurate tracking
- $50-$300 for processing software (there are free packages out that stack and do similar, but to do full processing you usually move into the paid stuff). And generally you end up buying multiple packages because certain ones do certain things better.
Heck, even simple live viewing for DSO's will set you back around $500 (usually a little more) when all is said and done for a decent into level Dobsonian or reflector/refractor. And many of these are not up to astrophotography level, which many eventually dive into that rabbit hole.
And there are the endless eyepieces that you pursue for live viewing so you can try to grab as much light as possible as well as magnificiation.
You can get in "cheap" with simple binoculars for solar system and some larger Messier objects - I have a pair of Celestron's coming in to use when we get our local astronomy group up and running, but still will need a decent tripod for them since they are around 5 pounds weight and it gets tiring holding those to your eyes.
One of the big problems... one scope is not enough. I'm up to 3 now and am jonesing for a F/4 astrophotography reflector to add to the stable with a new mount.
