Title: IC5146 - The Cocoon Nebula...
Post by: JohnP on Sep 24, 2006, 22:06:21
Hi All,

Went out Friday night & decided to try & get the Cocoon Nebula.... This was on my target list at last DSC but never got a chance to image it because of the clouds...

Image below represents 100 X 45 Secs guided exposures with SC3 & MN56 & 0.5X FR with Astronomik CLS - I really need to get myself a filter wheel so I can try some RGB... The Cocoon nebula is mainly a hydrogen gas cloud & open star cluster (IC5146) consisting of mainly 12th mag stars - there are some interesting dust lanes in the nebula. It is actually quite a dim object & was quite tough to process without introducing too much noise.

Anyway as usual comments very welcome....

Cheers,  John.

Fantastic, John, it is a change to see an image of a less common subject.

There is no holding you back now you are guiding. Oh God, not something else I will have to learn!!!!!!!

Hi Fay,

I must admit you made me laugh.... :-) If you want to learn to guide you will need two LX webcams & you have to run two lots of K3 on your computer at the same time plus a load more cables... You'll also need to expand the USB ports on your laptop if you haven't already done it... Like I said the other day it takes me about an hour to set up now.... Until you reliably get your single SC3 & K3 working I wouldn't even try it. I'll be pleased to show you how mine all links together sometime...

Thks for the comments on the picture,  John.
