A few hours with Corona Australis

Hi everyone,
Finally sat down and actually finished off a few more pictures which are building up on the hard drive. This is my third attempt this year of this and this one came out rather well. Last two attempts focus drifted and those dust bunnies got to breeding! Managed 40 x 5 min @ iso 800 with cooled 40D and 8" newt.
Spent a bit more time on this one in PS to try to get the dust and reflection neb to stand out. Another 40 subs should make this one real nice, but all in all happy with what I have managed so far.
All comments / critics etc welcome!

cheers Gary

Hi Gary,
Stunning!
I like everything in the shot, composition, color, processing, contrast, you name it.
Congratulations and thanks for sharing I loved it.

Which part of Corona Australis is this if I can ask?

Thanks Alan, yes I am quiet happy with this combo, A OSC would be nicer but . I thought by now that I would have killed the 40D but it keeps plugging along!

cheers Luis! glad you enjoyed the image!
This area is on the northern end of the arc of stars not far from Gamma Corona Australis which would be to the left of the picture and around RA19 hrs DEC-37 degrees

Wow, that was a surprise. That is a beauty. Only minor suggestion would be a bit of light deconvolution on the stars (not the object) which seem just slightly blurred or soft.

Greg.

Very nicely done Gary; a terrific result for a DSLR shot.

How do you cool a DSLR?

Cheers

thanks Greg, I usually do some slight decon on my images but it did introduce a bit too much noise into the darker areas, so didn`t do it with this image. Havn`t mastered how to do this on only stars?
cheers Gary

Thanks Martin, doesn`t do too bad a shot the old 40D
Cooling a DSLR is quiet tricky, most just put it in a peltier cooled box but I went for the direct approach by cooling the cmos directly like CentralDS with a copper coldfinger....Works ok but not as good as the commercial job or as pretty! Will pull the cmos down 20degrees below ambient.
Attached a picture of the camera just after the modd, not quiet finished but you can see the finger sticking out the side..No frosting problems as of yet.
cheers Gary
