I have a 8" Skywatcher dob tube as well, and just got some 230mm rings. They seem a little tight, and Im concerned if I do them up the are going to buckle the tube.
Does anyone else here have a Skywatcher dob tube and are using 230mm rings ??
Its only a 5mm difference though, I wonder how tight the 235mm are..
Thanks
