This video shows my full workflow for data acquisition with ASIAIR and processing in PixInsight for the Lobster Claw Nebula (Sh2-157). I worked for 2 nights but could only gather about 8 hours of acceptable data. Most of the subframes were rejected due to thin clouds. 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 used 20 Dark, 50 Flat and 50 Dark-Flat frames for stacking in PixInsight (WBPP). The PixInsignt HOO process is specific to OSC Cameras and Dual Narrowband filter (Optolong L-eXtreme). The HOO image created in PixInsight was further refined in Photoshop.
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.
