Since my imaging drought has lasted so long, I'll take any excuse to post . So, here is a "work-in-progress" of NGC 6822. As you can see B&W only - about 4.5 hours of Lum & Ha in equal portions. Needless to say the only decent imaging night during the current no-moon period was Sunday night. Seeing was good though.
Nothing awfully exciting yet but I'm pretty happy with it and it will look much better with a bit more Lum and some RGB. This is quite a photogenic galaxy, especially if you add a bit of Ha to make the emission nebs pop and process the blue star clusters properly. I believe the data is just starting to show galactic cirrus too but it's too faint to push too hard without getting a lot of noise - it's there though!
That's looking reeeeally good Marcus; you seem to have the collimation under control now! Seeing was obviously quite good as well so the final colour image should be specatcular

Thanks David! Yes, my collimation journey was "fun" . Seeing was very good for the first few subs and then deteriorated as altitude decreased. Average FWHM for the combined session after some light decon was 1.97 arcsecs. This compares to the first 2 subs of 1.87 arcsecs without any decon. Oh ... to have that kind of seeing all the time!

I have never imaged that galaxy but I think its quite a dim object and your image is showing it clearly so that is great.
Greg.
Thanks Greg. Over the moon mate. OS delivered on the promise - it just took me a while to get my drivers license! And yes, I do think this is a rather underrated object - there aren't many good renditions out there. It does need some image scale / focal length to do it justice though.
very impressive resolution Marcus - looking forward to the final result.

Clear skies

Thank you kindly Ray & Marco! Yes, pretty chuffed with the resolution and, though the seeing was good, it wasn't the best I've seen here! Fingers crossed the weather lets me finish it this month!
