I was out testing last night and this image LOOKED pretty good to me. I’ve taken a few different shots with different spacers. This is one with a distance of 58.5mm. I’ve also taken some at 59.5 but I think that is too much. Camera is a ZWO 071mc APSc sensor on a 200mm F/4 Newtonian.
Note : All measurements were taken outside the camera plus the 17.5mm claimed by ZWO. I haven’t verified that measurement.
Cheers
Ryan
