Helix Nebula


 
 

Took this over the course of two nights while waiting for the California Nebula to rise. First night had passing clouds for awhile so I can had toss a few frames. CLS filter helped bring out some of the HA around the nebula but I think this would be worth going back and shooting something like 6 hours of HA to get the outer shell to pop.

California Nebula


This was taken over the course of two nights from Tierra Del Sol, CA. Each frame was 3-4 hours of exposure time except for the top right frame, I only got 2 hours because of passing clouds.

I used my CLS-CCD filter which REALLY helps with lining up the frames. No feathering was done on the edges, just lined em up!
