Description

Imaged the Moon on December 20. 2020 (December 21st in UTC) while working out my imaging setup for the Great Conjunction of Jupiter and Saturn. The Moon provided a great target to work out the imaging train configuration and focus settings so I would be ready to roll during my short observation window for Jupiter & Saturn on the following nights. Imaged at three focal lengths: 478 mm (nominal focal length of the GT81), 956 mm (GT81 + Siebert 2x Barlow), and 1195 mm (GT81 + Televue 2.5x Powermate) to give me a range of options for Great Conjunction imaging.

Original: Imaged with a William Optics GT81, Baader IR 685nm pass filter, and ZWO ASI290MM. Imaging train was configured to give ~F/6 (`~478 mm focal length. Image capture using Sharpcap (Gain=300, Exposure=0.00025). Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in Registax (wavelet sharpening).

Revision B: Imaged with a William Optics GT81, Baader IR 685nm pass filter, Siebert 2x barlow, and ZWO ASI290MM. Imaging train was configured to give ~F/6 (`~478 mm focal length. Image capture using Sharpcap (Gain=300, Exposure=0.0005). Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in Registax (wavelet sharpening).

Revision C: Imaged with a William Optics GT81, Baader IR 685nm pass filter, Televue 2.5x powermate, and ZWO ASI290MM. Imaging train was configured to give ~F/6 (`~478 mm focal length. Image capture using Sharpcap (Gain=300Exposure=0.0015). , Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in Registax (wavelet sharpening).
