Thank you so much for your helpful responses everyone! I think quoting everyone would make it confusing to read so I'll just reply on this post
The photos from the 10" Skywatcher dob that TwistedRider posted are very nice. I'm starting to think that maybe a 10" telescope would be better for me because of its size and everything else, but I'll still try to look at a 12" telescope if I can and then make a decision. I still have some time left to decide. I checked a light pollution map and it says that the area I live in is Bortle 7. I don't go to any dark sites but I may do that in the future though.
I'll look into getting a trolley, that would make life so much easier. The area I use my telescope in has solid ground and the place I'll be storing my new telescope in won't be too far from there. My 6" telescope requires carrying it a longer distance as I store it inside the house and that is something I definitely won't be doing with the new one!
Also, I wish I could get a refractor telescope! They're just so expensive
For now I just want to explore the sky and see a bit better than what I'm able to see now so my focus is larger aperture and some new equipment to make my experience better
I have two questions for ya'll, what size is your telescope/your most used telescope (if you have more than one)? And what are some must have equipment/upgrades for a telescope that you can't do without?
