I used the 300mm flourite f2.8 lens from Bert to get the Orions Belt area. Conditions not good with cloud patches and haze, I will try and get a better image of it next time.
3x10 mins ISO400. Houghys cooled DSLR and CLS filter. 300mm f2.8 lens. I got some of those greyish globules one is between the belt stars.
Gee its a good lens, no image quality fall off at the edges at all even when wide open.

It really shows how getting rid of noise gets you the really dim faint nebulosity even at f/2.8. I have only seen faint hints of the greyish things you mentioned Scott. I am still experimenting in cooling the 5DH though nowhere near as cold as the cooled camera you used.
Thnks all
I would love to repeat this under a dark sky. Teaming up the amazing lens and camera under an airglow limited sky would be unbelievable. When processing this image it was so exciting to see faint stars seemingly only 1 pixel in size when displaying the subs at full resolution. Flourite coupled with Canons workmanship is a fantastic combination.
I will have a new guidescope in the form of an 80mm refractor to replace the $80 Halleys Comet special focal brand guidescope I currently use to guide both this lens and my 6 inch SN. The rig as set up for the lens is here http://www.users.on.net/~josiah/mod350d/300mmlens.jpg
Im stoked that manually guiding this rig for just 30 mins total produced this pic from a very light polluted sky. Under the sky Theodog has, with this setup the Horsehead would be too bright!
Thanks all
Thanks for doing that Jeff. Gee the SBIG is sensitive. I will definately earmark this area as something to image from a darker sky if at all possible
Heres a full sized view. look how small the faint stars are even at the edges. Bit noisy, I do want to do more subs at a darker sky. http://www.iceinspace.com.au/uploads...00cls300mm.jpg

. I might see what I can do if it's clear tonight.
