Description

First Light for my new ZWO ASI533MC Pro on my 11" RASA replacing my ASI294MC Pro. I liked that this smaller chip camera gives me a little smaller FOV over the 294. This is 158 x 60 sec subs, processed in the lastest PI with WeightedBatchPreProcessing. WBPP took 31 minutes but it did make a master dark, flat, bias as well as the light that I processed in PI the way I usually do.
Comments welcome.
