Hi;
so last night I used for the first time the autofocus function.
my setup:
EQ6R
110mm Altair.~650 Focal Length with reducer
ASI1600mm.
Eagle Pro
ZWO filter wheel (5- R,G,B,Ha,Oii) and autofocus.
70mm guide scope with ASI120mm
I used the setting to autofocus after each filter change. It was “ok” but it takes a while between each filters, I guess about 1 minute. But sometimes its off (well once or twice) and I’m not convinced that its as good as a Bahtinov mask.
I did setup at 4x4 and 2 sec. my gain is at 64 on my ASI1600. I was doing the Veil nebula NCG6995.
I would love to get some insight from more experience people and suggestion to maximize this process. Do you need to refocus after each filters? Can you filter once on the red and keep the same focus for G and B but do it for Ha and Oii?
Thank you!
Michel
