I'm looking to see if this is acceptable guide numbers for the sky watcher star adventurer, RA ONLY. I've gotten it as low as 1.15" and up to 4.0" at times. This is about average. Star are round and sharp, no trailing.

I've taken it apart, cleaned and relubed it. I make PA is spot on and everything is balanced. 

Astrotech 60ed 60x360 f/6 scope.

Hi Keith, I typically achieve 1.2-1.5 "/px with my SA 2i, and sometimes as low as 0.5"/px with good balance and polar alignment. Short exposures tend to work best, I use 0.5-1s but be careful of 'chasing the seeing'. I use EKOS (indi) for guiding with Stellarmate OS on RPi4/5 which works well with the SA 2i  - I've achieved 10m exposures using a 436mm focal length refractor; that said much happier with a lighter load.
