Omega Centauri with canon 300D

My son and I imaged Omega Centauri last night-despite a bright half moon - with the Canon 300D and Celestron C8 NGT, autoguided with GuideDog(Atik 1 c webcam @2 seconds exposure , 60 mm refractor guide scope). Manual focus.

composite of two images at ISO 1600-one exposure was of 224 seconds and the second was a 20 second exposure.

Gradient removed in photoshop, also levels stretched , brightness and contrast tweaked.
Noise removed in NeatImage.

Nah, Seeker, that's not good enough. On close inspection your picture is obviously a fake. It is a good fake but it is a fake. There is a photo of NGC 5189 on the wall at Monash Uni Physics Department and it looks nothing like the digital so-called photo you've posted here.

Beautiful Seeker! Well done.... Focus spot on, which is the hardest thing to acheive on Globs. Your seeing must have been pretty good...
Cheers

Lovely shot - beautiful image....

.....I think it also may have a tiny bit to do with the skill behind the scope set-up, guiding & imaging too.

Thanks for the feedback and nice words people

I have to say I think autoguiding has made a quantum difference to image quality...even spending hours trying to drift align never gave me the tracking accuracy to allow really long exposures.

Guidedog rules!

It is a fabulous shot Seeker, worthy of any world astro/science mag.
Just a question, you say auto guiding has made all the difference but exactly how good was your polar alignment to start with?Was it spot on, near enough, kinda close, a little bit out, really near to the SCP.....how good was it?
Focusing is brilliant too. Any tricks or masks there or trial & error?

for this particular image polar alignment was way way off. ..usually it is much better, but still I had no problem with individual images. However when you go to stack a number of image I found some field rotation..that is because it was so hopelessly far out

focus is pure trial and error..
I have to try DSLR focus though as I hear it is very good-written by an Aussie and costs around $50
