I'm running a second rig with a mono camera, and decided to give the SHO palette a try. Elephant's Trunk Nebula is both beautiful and fascinating, with tendrils if gas and dust formed by the interplay of young stars and the surrounding gas & dust.
I used an Askar FRA 400 telescope, an ASI 1600MM Pro, OIII, SII and Ha filters. I used 15.5 hours total integration. It was processed in Siril, Starnet++ & GIMP.
