So I recently got the Pegasus FocusCube v2 and connected it to my GT81. I plugged it in, setup the software and ASCOM drivers. That night, I took the rig outside and played around. First, I used the manual controls and my GT81's built in Bahtinov mask along with NINA's focus assist to get a pretty bang-on focus. Next I started playing around with the auto focus in NINA and this is where my questions started to pop up.
I can set a step size as well as backlash compensation. When I first started playing with auto focus in NINA, it kept telling me my step size might be too small. So, I increased it. I also noticed that in the Pegasus software for the backlash compensation, it says the Pegasus should be set between 30 and 40. So, not having a clue if I even needed to compensate for backlash, I set it to 35.
My setup "seems" to auto-focus pretty well, but I really don't know if it's setup right, or how to diagnose what might need to change - if anything. For example, when the auto focus runs, it gives me a pretty decent parabola, although the bottom of it is a bit flat, rather than a nice curve down to the bottom of the V.
Any helpful setup tips or recommendations on what to look for?
Thanks in advance!
