Description

My first attempt at guided astrophotography. Decided to skip astromodified DSLRs and OSC cooled cameras and go straight to cooled mono astro cameras.

Used astroberry/ekos for the subs and cal. Was aiming for just M42 but got the Horsehead nebula as well as a happy surprise! Mapped Ha to red and O3 to blue since I felt that might be most realistic. S2 is mapped to green but doesn't really seem to show up.

Lens is stopped down to F3.5ish. Focusing is difficult with this setup at night and there is a slight aberration in imaging train either from sensor or lens mounting or misaligned lens elements.

Amazed at the detail one can get using narrowband in a moonlit and bortle 9 zone!
