HIP102483 region in SHO and Hbeta

No Comments

HIP102483 Cygnus region in narrowband, SHO and Hbeta channels.

This is the first of a couple of panel mosaic of narrowband recording focused about NGC7000 region in Cygnus; subframes of 180sec at -20C taken between 28/05/2023 and 22/08/2023 with ASI1600mm Pro under William Optics Redcat 51, mont EQM35 Pro.

SHO classic palette integration, with annotations

Ha Oiii and Hbeta palette integration

My preferred integration, with Sii for red channel, Ha for green and Oiii + Hbeta for blue.

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.
