I got a nice Vixen ED115s yesterday. I paired it my NEQ6 and SBIG STF8300 camera with OAG. The updated Moonlite autofocuser was found to be successful during the initial test, however, I got really poor guiding. The first thing I noticed is during calibration, I heard quite noisy sounds when clearing the backlash. The second thing I found is that the dec is not balanced from left to right because the extra motor of the Moonlite focuser.
I guess the calibration maybe wrong because of the wrong parameters. The unbalanced dec may also cause the problem. The scope is definitely longer than my previous ED103S. I would appreciate it if you could help on this. I attach a snapshot of my guiding graph. Thanks!
