Galaxy M51 recorded with Zwo Seestar S50 from home balcony.
IMHO Seestar S50 10sec subframes stacking is the live demonstration about the validity of Jon Rista (https://app.astrobin.com/u/jrista#gallery) approaching to short time exposure DSO imaging.
Spikes generated with Star Spikes Pro in Photoshop.
Cone Nebula and Christamst Tree cluster and nebula region in LRGB. Subframes of 300 and 600 seconds taken with a Proline FLI PL16803 on ASA 500N 50-cm F3.6 corrected Newtonian telescope, from El Sauce Observatory of Chile, Telescopelive network.
NGC6823 in SHO palette, with Ha as Luminance layer as according to gamechanging approach of Nik Szymanek approach to Sulphur-II Luminance Compositing.
Data retrived from Telescoplive network, IC Astronomy Observatory of Spain, Officina Stellare ProRC 700, CCD Proline FLI PL16803.

NGC281 in SHO narrowband palette, with Ha integrated as Luminance layer, as according to to Nik Szymanek approach to Sulphur-II Luminance Compositing.
Ha layer (luminosity blending) added in starless and stars separate layers.
SHO stunning integration

NGC281 integration by summing several records in SHO narrowband by William Optics Redcat 51, ASI1600mm on EQM35 collected between 2021 and this year.
According to to Nik Szymanek approach to Sulphur-II Luminance Compositing I added Ha band in starless cleaned version as luminance within Photoshop postprocessing flow.
