Dec 25, 2019 Rosette
My first attempt with the Rosette nebula, shot with the ASI-294 on a clear and calm night near Natural Bridge, VA. Temps were about 30 degrees F, calm winds and very dry air. Seeing was great. New moon. SQM about 21.2.
Details: 90 minutes with 2.5 minute unguided exposures using the Samyang 135 mm lens wide open at F2. Gain set to unity (120), temperature set to 0 C. Mount is Orion Atlas Pro. Used SharpCap for capture, PI for all processing. Had to throw away about 5 exposures (12.5 min) due to thick smoke clouds from neighbor's chimney drifting overhead at times.
Used HDR multiscale transform in PI to bring out more detail of dust lanes to fairly good effect. This image is cropped considerably from the original in order to see better detail.
