NGC2403 in LRGB

No Comments

NGC2403 Galaxy in RGB. William Optics Redcat 51 and ASI1600mm Pro, 60 seconds LRGB subframes taken at -20C between 10/09/2022 and 13/02/2023, suburban 6 Bortle scale sky (Livorno – IT).

Final image is the 2nd cropped version from the wider range integration

Less incisive cropping as first attempt to get more focusing about NGC2403

Draco Trio in LRGB

No Comments

LRGB record of Draco galactic trio NGC5985, NGC5982 and NGC5981, from IC Astronomy Observatory of Telescopelive network, Officina Stellare ProRC 700 and Proline FLI PL16803 CCD camera, subframes of 300sec.

These galaxies are roughly 100 million light-years away. The faint, sharp-edged shells surrounding elliptical NGC 5982 suggests evidence of past galactic mergers.

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.
