I've been getting back into astronomy recently due to me taking an astronomy course this semester. I used to have a cheapo Meade refractor telescope from Costco a while back but that thing was terrible and only frustrated me. I want to get serious this time and invest in a quality beginner telescope that will last me a while until I want to upgrade to something with a big Aperture. The thing is, I live in a densely lit up city with a serious case of light pollution preventing me from enjoying the night sky. Just so you get the picture, I can barely make out constellation like Pegasus and Scorpius with Cygnus being the only one most identifiable. So what I'm asking is if its worth to invest in a 300-400 dollar telescope with these conditions? Right now I'm looking at a 6 or 8 inch Dobsonian Reflector by Orion. If you have any suggestions, please let me know.
