Back to the ZWO 183mm pro
Decided to image this target again but this time with my 183mm pro which has a much smaller image scale at 0.89 vs 1.43.
Definitely no microlensing issues even with the O3 filter, this was taken with gain at 53 and approximately 40 subs each at 240sec for Ha and O3 and 300sec for S2.
Thinking I'll keep this camera on for the time being and upgrade to the 2600 or 268 mono down the track.
