Description

Here's my first try at mono imaging with a huge shout-out to my good friend @gazingoutwards for making it possible with the ASI1600MM camera and Astrodon filters! This was a really neat learning experience and I'm excited for more clear nights to keep learning the ins and outs of mono imaging and processing.

I love the Orion Nebula... aside from (maybe) the Andromeda Galaxy... I can't think of any other object in the sky that is as easily recognizable and picturesque so it seemed like a good target to shoot for with my first mono image.

Due to the vast variation in brightness, M42 is actually pretty difficult to capture in a single exposure length. Due to this, I captured 50 10 second exposures for the brighter areas and merged that with 75 60 second exposures of the dimmer areas to get the best of both extremes. In hindsight, a medium 30-second setting would have helped....as would some 120-second shots for the really faint surrounding dust and gas areas. Oh well, space isn't going anywhere so there's always next year!

Image specs:

Taken 2/16/2021 with Zwo 1600MM Camera, TS Optics 130AP0 reduced .80, Skywatcher EQ6-R Mount, Astrodon LRGB filters.

Luminance= 75x60" & 50x10"

Red = 30x60"

Green = 30x60"

Blue = 28x60" (clouds rolled in)

30 dark frames, no flats or dark flats... I was just too excited to get the data processed.

Total integration time = 2.8hrs
