Description

First light with APS-c upgrade from the ASI294mm. So far, I am pleased with the ASI2600mm, but I do need to figure out the flats. Not sure the ADU at approx 32k is right for this but I will explore more. I initially preprocessed this with flats, but my green filter introduced a pesky dust mote that was too much trouble to remove. I restacked without flats and did some heavy cropping to lose the vignetting, but the resolution seemed ok and the target was small enough that I think it worked. I simultaneously shot the Iris nebula and decided to avoid the green flat by using the blue one. That seems to be working, so I guess I could go back and do the same with this data if I ever want the wider field. Maybe during a cloudy streak.
