Description

Miraculously, we had couple of clear nights. It has rained 175% of normal in Northern California. I performed a test. I went through a full day of stacking with PixInsight and compared it to one hour of stacking with DSS. I found that the quality was difference was negligible and the effort difference was enormous. I am going to stick with DSS to stack from now on. PixInsight is far too cumbersome and not user friendly.
