M33 from IC Spain Observatory, LRGB 600sec subframes recorded between 28/09/2021 and 16/01/2022 by Takahashi FSQ-106ED with Proline FLI PL16083 from Telescopelive network; astrobin https://www.astrobin.com/zkhypx/C/
Original widefield cropped twice
to better focusing about Galaxy.
M33 Galaxy lies among my best favourites targets and IMHO it is very difficult to be photographed.
Helix Nebula in narrowband, HOO and SHO palette.
Data retrieve from Telescopelive network, El Sauce Observatory in Chile, Planewave CDK24 with QHY600M Pro CMOS camera, subframes of 300sec recorded between 30/06/2023 and 02/07/2023.

SHO palette integration.
Starless and star composition made in Photoshop, with different fixing and adjustement layers; .psd master for SHO available here, and HOO here.
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.

I’m totally in love with Cygnus region, and try a 2 panel mosaic work focusing about NGC7000 and surroundings.

This is the second of a 2 panel mosaic focused about this region of Cygnus, so rich and beautiful! Subframes recorded between 27/05/2023 and 12/09/2023 with William Optics Redcat 51 and ASI1600mm Pro, at -20C, gain 173 and 180sec of exposition; some subframes at 300sec expecially for Halpha channel help in faint nebulosity detail emerging.

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.
Astrobin: https://www.astrobin.com/w0ah2q/
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.
2 plates mosaic for this region of Cygnus.
Hbeta narrowband channel I used to integrate Oiii data.
