Help re: Zwo EAF Step size for autofocus Quattro 200
Hi Everyone
Would be grateful if you could share your settings for ZWO EAF Autofocus for this Newtonian. Tried a Quattro 200 out last night for the first time and couldn’t get the FWHM below 7 with the EAF autofocus.
The stars were also a little egg shaped and in the morning I found the collimation to be out quite a lot. Now readjusted.
Presently I have the EAF step size for autofocus set to 30. Gives a fairly shallow V curve. I’m using a Sharpstar 1x MPCC, IR/UV CUT filter, back focus is 57mm (2mm extra for the filter).
Many thanks
Chris.
