My best ever Corona Australis pic

[tornado33]

Hi all
Got Corona Australis last night. I wanted to see if I could reach deep enough to get the brown smokelike dark nebulosity, as well as use the photoshop masking technique as shown here http://www.astropix.com/PFA/SAMPLE4A/SAMPLE4A.HTM
Image is 4x 5 mins ISO 400, uv/ir filter and MPCC. 10 inch F5.6 newtonian, Modded 350d camera. processed in Iris then Photoshop and Noiseware

Gee Scott, that's a nice capture with excellent processing. The composition is superb with that beautiful globular; nicely resolved too.

Cheers

Excellent work Scott, how wide is that FOV?

[ving]

great stuff scott!!!
just like it looks through an eyepiece (not)

beautiful :)

Came out very well Scott. That 'dark' nebulosity is very dim (DUH!) I think it is front lit by nearby stars and by sky glow and light pollution?. The blue reflection nebulae are also not very bright.
A really lovely capture of a difficult target. Shows how good your mirror is now after recoating.

You got to love that blue nebulosity Scott..well done.

one of your nicest images, Scott

[tornado33]

Thanks all :)
The FOV is such the full moon just fits in without touching the top and bottom.
Yes it almost looks like the is space pollution with the dark brown cloud. I should re-image it again without the uv/ir filter and see if excess infra red comes through.
This also demands re imaging with Berts 300mm lens too.

Taken with a Hutech LPR filter knocks out some blue.

You can see the detail and contrast is much better in Scotts picture.

Thanks Bert, I thought of using the uhcs filter too, but as theres little ha narrowband emission I though it best to use only the uv/ir filter. I will re-confgure my mount back to use with your lens and shoot with that next few clear nights.

[EzyStyles]

great shot scott. that dark neb is hard to come by. You have captured it well.

here's my version lol

[tornado33]

Thanks all. Good shot of the reflecton nebula Eric, its a strange area of sky isnt it?.

cheers scott sure is strange. I remember was looking around for it then suddenly no stars at all from a section of the sky. very weird experience as i never come across seeing a patch of the sky without a single dim of star.
