Tonight was average seeing and getting worse as the evening progressed. I tested out my earlier target -- M1 using the following set up for short exposures and high gains:
C8 Edge HD
ZWO 294 MC Pro, binned 2 x 2 (seeing did not permit usage at 1 x 1)
Exposures: 2 seconds and 5 seconds
Gains: 450 and 570 (max camera can do)
No darks or flats (i need to generate some darks at 2 x 2 binning)
Duration: Roughly 10 mins
While the 294 is not a good fit for RASA 8, it seems to work well with my C8's. Especially given the noise level is really low, I can turn up the gain very high. So wanted to compare a couple of short exposures.
First here is
exposure = 2 seconds, gain = 570. I kept the color saturation as low as possible to showcase the details a bit more.
