After doing this area with the 300mm lens, I had a go with the 50mm lens last night.
13x5 mins ISO400. Canon 50mm f1.8 @f3.5, modded350d. IDAS LPS filter

It is like a negative of a comet, a dirty brown one against the stars.

I knew from day one you were a very innovative astrophotographer Scott. Thank you Scott for that gem I will remember this always. Reminds me of dusty lusty Dusty Springfield. Could be the dust is the common theme!
Very mind changing. The mass in that dark nebula could make thousands of solar systems?
Superb!

Thanks Bert
The LPS filter in combination with the excellent 300mm Flourite lens, and the 50mm lens, work very well, when weather permits I must hunt down other dark nebulae. The LPS blocks common light pollution bands but allows plenty of broadband light from astronomical objects in. Even daytime test images taken with it dont show much colour shift.
Indeed, all that dust indicates the stuff terrestial planets would be made of. Much of it would have been forged in the heart of primeval supernovae, and may go on to form solar systems like our own. The Universe is an amazing place :)

Scott,
Quite cool that you chose such a low surface brightness object at such a wide image scale....and this I like immensely....
...but at the scale presented, I'm sorry I can't join the PC accolades..looks like a smudge on a piece of sandpaper to me. Needs more data, dynamic range and more scale....but hey, don't take anything I say to heart.
Cheers
Peter

Thanks all
Heres a full sized version (http://www.iceinspace.com.au/uploads/coronaaustralis13x5minsiso400lps350 d50mmf3.5_filtered.jpg), with a very small amount of n/r done with Noiseware. Its 3.39MB
If it was taken from a dark sky site, especially with double the time, it would be fantastic.
In the days of film Id dream of getting just the above result with film from the darkest of sites and many hours of exposure.
EDIT:I didnt do any star size reduction on this one.

Nice wide shot of this! Scott. Looks like a bush fire in space.

Thanks.
I wasnt 100% happy with the full sized version so I replaced it with this, same link (http://www.iceinspace.com.au/uploads/coronaaustralis13x5minsiso400lps350 d50mmf3.5_filtered.jpg)
