NGC7293 Helix Nebula Aug2015sm



This is a reprocessed image of the Helix Nebula Data I captured and posted previously.

 

This image has been exposed across 4 nights, 2 nights through a HAlpha filter and 2 nights through a OIII filter using my modded 40D.

 

 

Helix nebula is fainter than I thought it was going to be, I had to image it at ISO800 30 minute HAlpha subs and ISO1250 OIII 30 minute subs, total of 8 hours through each through my 8" SCT at F10.

 

 

I just wish I captured more clearly the comet shock waves visible in the Hubble images... But overall I'm happy with how it came out... As always there is room for improvement...
