This is my second round of the ASI533MC Pro testing. Again a popular target is selected in order to give better base for comparison. In this project didn't use any filters in order the camera own performance. Other change is that the gain is a bit lower than the unity, trying to increase dynamic range.

As additional note, have to add that 2/3 of the frames were taken with moderate sky :( This winter was not generous and had to use what is given...

I'm quite happy with the result :) The camera is sensitive and gave deep look on the object even with the smallish 80mm refractor.
