My recent image of Orion nebula, shot with my tracker, Sky-watcher Evostar telescope with reducer (336 mm final focal length) and Canon T3i, H alpha modified. I stacked 144 images of 60 seconds each, iso 400, in Deep Sky Stacker then stretched the image in Images Plus. The dark skies in Brentwood Bay on this night (Jan 27, 2025) allowed me to shoot without any filter. Typically city light messes up my efforts.
