Monoceros Gems.
Hi,
I’ve been concentrating on some of the gems in Monoceros,so I’m posting them in one post.
IC 447 is the final of a progression of images. See previous.

It has more faint outlying nebulosity showing, and isn’t quite as noisy.
This is a total 93 x 2 minute subs, ISO 6400.
NGC 2170 is faint, quite a challenge to get anything out of the data. I think it looks like an angler fish?
62 x 2 minute subs, ISO 6400.
The sky was bright with dust, so the subs were washed out a little, might try longer subs at ISO 1600.
Don’t Know whether this will make any difference?
IC 2177 was the big surprise!
This is only 32 x 2minute subs at ISO 6400 and happy with the result from my unmodded 1100D.
Quite a lot HA coming through, I tried imaging it before and really didn’t get anything worth processing.
8” F/4 astrograph , baader type 3 coma corrector,. HEQ Pro 5 mount, orion mini guider.
Camera.
Unmodded Cannon 1100D plus cooler box. All images tacked in Deep Sky Stacker .Processed in Photoshop Cs2..
Cheers,
Justin.
