I have a 6" Celestron Evolution 6"which I bought as my first telescope. I didn't want to commit to anything more expensive when I bought it until I could prove it wouldn't become a coat hanger in the corner of the room.

I've been really happy with it, and can observe far more than I imagined from my city location. With 9 months use or so I've therefore been considering upgrading the OTA to a C8 XLT, which I was led to believe would be a straight forward swap, both the 6 and 8" versions using the same GoTo.

I wondered if there would be a noticeable improvement between the two different OTA sizes? I'm not really quite sure what to expect and it's still quite a significant purchase.
