Since it's that time of year, here's my take of the Orion Nebula.

~12.5hrs of total exposure over several nights, where I took groups of 30, 60, 300, 480 and 540 second exposures and created an HDR blend.  I thought 30 second exposures @ ISO1250 on my EOS RP would be sufficient to capture the bright highlights of the nebula, but apparently f/4 was still too much light and I blew out the highlights.



Mount: ES PMC-8 EXOS2-GT
Scopes: BRESSER 208mm f/3.9 Newt + ES HR Coma Corrector, Celestron C90 Mak, generic 50/191mm guide scope

Misc: 2" Optolong L-eNhance filter, 2" Optolong UHC filter, Raspberry PI 4
Software: INDI + Kstars + EKOS, DeepSkyStacker, GIMP, Lightroom, Photoshop, SIRIL
