I use this mount with a 5 in short tube refractor. (127 Explore Scientific.) Nice Ballance between portability and mass. Setting rings are cheezy, but never intended to use them with this set up. Any more scope than this would need more mount.
Pros: Solid tripod. slow motion controls smooth
Cons: setting rings useless
