Description

This is NGC 986 captured on 22 Jan 2022 from Iluka, Western Australia. I captured 67 x90 second exposures at gain 120 with the camera cooled to +5C instead of my historical setting of -10'C. 39 frames were good enough to stack, the rejected frames were impacted by poor seeing and occasional high cloud.

A 90 second exposure is around the optimum setting for my Bortle Class 6 sky using the calculation principals recommended by Robin Glover in his you tube video. I do think there is an overall quality increase (particularly in respect of star colour) using 90 second exposures and so I will continue evaluating this setting in the future.
