Description

Comet Leonard C/2021 A1 from iDK Namibia remote telescope, Skygems.


Very hard but completely stocked within this processing; mosaic is obtained by 4 different kind of imaging, at different binning. BIN2 mosaic in LRGB consisted in 3 framing. one for the comet head, another framing for the middle comet tail, third framing for distal part of comet tail.
Bin1 Luminance set finally integrated within mosaic.
Final star & starless integration in Photoshop, with numerous adjustement layers and pixel fixing needed.

Dataset available for free from Skygem network here: https://forum.skygems-observatories.com/d/104-new-year-present-c2021-a1-data-set
Calibration is not quite easy as Skygems archives missing proper dark for right calibrated masterflat creation.
