Hi,

I have a new Edge C11 at FL 2800 and want to optimize my Mach1 performance (and guiding).  I have collimated the scope and the is luckily almost no tilt.  I am using my ASI 6200 and will be binning images at 4x.  So far so good.  First light:

I want to optimize my Mach1 performance and have not touched it for a couple years. 

This video gives a nice overview of the main factors to consider (and I have done them all):

Except the weather has been marginal and I have not checked my PEC.  I believe I am still using the "factory" PEC that came with the mount.  I believe that I could not improve on it.

Is there a way to check which PEC one is using?  And whether you have loaded a new one or not?  Can you choose and backtrack if not happy?

Suggestions on other factors to consider after (Polar Alignment with PEMPro, scope balance, adjust backstop of gearboxes, use ACP script for Maxim guiding calibration)?

I see APCC has been upgraded... did not find the pointing model to have helped in the past, but maybe it is worth it?

Thanks for any help as this is the longest FL scope I have ever used.
