The Great Orion Nebula, NGC 1977 & NGC 1981
Yesterday
on a very clear night I decided to take photograph of Messier 42, The Great
Orion Nebula. I used my Sky-watcher short-tube achromatic refractor for the
first time to photograph this object. I used my unmodified Canon EOS 550D and
took 10 JPEG images, each lasting for three minutes at ISO 1600. When stacked
this morning the final image that came wasn’t very promising and there was lot
of noise.
I
then deleted four images having little trails and processed rest of the images
in Photoshop before I stack in Deep Sky Stacker. I adjusted levels and reduced
the noise in each six images and then stacked them in deep sky stacker. Finally
after post processing in Photoshop CS6 this is what I got! Below is the detail
of my set up and camera settings…
