You can probably buy a decent 8 or 10 inch Dobsonian for around $500. But there is a learning curve to this sort of thing. If you haven’t already spent some time with more modest equipment such as binoculars, it will most likely end up as a garage ornament.
I was just wondering what power you need to view other galaxies without them being just smudges of light. Rent time on the Hubble, LOL?
