Astrophotography: Imaging NORTH AMERICA NEBULA With GT71, ASIAIR, ASI533MC Pro & L-eXtreme Filter.

#ASIAIR #ZWO #Astrophotography This video shows my typical workflow for data acquisition and processing in PixInsight for the North America Nebula (Caldwell 20 or NGC 7000). This is the imaging setup I used: Telescope: William Optics GT71 Main Camera: ZWO ASI533MC Pro Guide Scope: William Optics Slide Base 50mm Filter: Optolong L-eXtreme Guide Camera: ZWO ASI120MM Mini Mount: Celestron Advance VX Control: ZWO ASIAir Plus I worked for 2 nights but could only gather about 5 hours and 32 minutes of acceptable data. Most of the subframes from one night were rejected due to clouds. I used 20 Dark, 50 Flat and 50 Dark-Flat frames for stacking in DSS. The PixInsight process is specific to OSC Cameras and Dual Narrowband filter (Optolong L-eXtreme). I created 3 different colour combinations by extracting the R, G, and B channels. I hope this video is informtive and useful. Please let me know in comments if I missed anything. If you like this video, please consider Subscribing to my channel. Thanks for watching!
