This one was one of my better images taken in 2012.   I had a new camera and I was putting it through its paces.

The beautiful California Nebula in Perseus.

This was 84 sub-images of 3 min each at ISO 800 combined with 5 subs of 15 minutes each shot at ISO 400.  All images done with a Televue TV-85 with a 0.8x focal reducer for F/5.6 speed, a Canon T3 modified DSLR camera and a IDAS-LPR filter.
