Helix Nebula - NGC 7293

Here is a shot of the Helix Nebula taken from the mountains just east of San Diego. There was a fortunate conspiracy of good seeing, clear skies and good guiding for this image. In addition to RGB exposures, I took both H-Alpha and broadband luminance (with IR/UV blocking filter). I am glad I did both the H-Alpha and Luminance - their blended result produced a better image than either separately. A full size image and exposure / processing details are at:

Scope C8 @f/4.8
Artemis285 H-Alpha, IR/UV Blocking, RGB filter exposures
G11/Gemini
Guiding - Megrez II at 1350 mm FL, DSI Pro, PHD Guiding

I have imaged this object a couple of time previously. Those images can be seen here:

Nice one Jim,
Wish it were a little higher here, but maybe soon I can take a shot at that object with the new setup.

hi Jim,

thats ia a grewat result on that nebula!
having seen the earlier versions, the recent one knocks me out of my socks!
clarity on the subtile "drops" near the core is terrific!
but I really LOVE the blue of the centra lstar!
that is right on!
wonderful!

clear skies, guys!

Fantastic image Jim!

I would add some data though to improve signal in the outer areas of the nebula: it would be spectacular with a couple of more hours here and there wink

Ciao Jim
