I have a Discovery Newtonian with a 10” mirror in a 12” tube. I’m 5’8” and is as tall as I am, lol. I can see gaps between the rings of Saturn on a clear, stable night.
I have a Telrad mounted on it and a finder scope. She’s a beaut! I bought it brand new in 2004 and added the accessories.
Discovery telescopes (not affiliated the Discovery channel) were known for there awesome mirrors. It’s sad they are no longer in business.
Btw, you can order a Telrad from Amazon for $52.95 US.
Best I got a couple of times was going to Pulpit Rock Observatory outside of Allentown PA. I can't remember the name of the type of scope my brother-in-law was using, it belong to the astronomy club he was a member of but I remember it was housed in not in a large rotating dome but it was in a type of large holding case that opened and the scope was mounted on a secure platform and had a 360 degree rotation. Saw the polar ice caps on Mars in beautiful detail. Just amazing. Was even on one memorable night able to see a very distant Neptune. A beautiful robin's egg blue as I remember .
