I have been having an issue with my ZWO 294C with some real odd spots showing up that I could not remove with calibration. Thanks to Johny (SkyWatcher) the problem has been solved. It appears to have been frost on the camera window. I can't thank Johny enough for his expertise. This had ZWO stumped.

This image is a simple test of 3 subs at 180 seconds for a total of 9 minutes integration. No spots to be found. No calibration what so ever ....just cropped to removed the vignetting. Satellite trail not removed due to only being 3 subs and it was a heavy one.

The ZWO ASI 294C is a very sensitive OSC to pull out this nebula with only 9 minutes of integration.

Also I would like to add the the support from ZWO was way beyond my expectations. Sam runs a great company with great products and support!!!!!

ZWO owner for life!!!!
