Thanks to the unusually long stretch of fine weather and fair seeing, I have had fun imaging from my observatory the past couple of months. The appended images are as follows;

1. M45 the Pleiades, is a multi stack totaling about 40 minutes of exposure with the AP-155 Starfire Apo refractor at f/5.2, all taken with a modified Canon 6D and IDAS LPS-V4 filter, shooting at ISO 1600-6400.

2. IC-5146, the Cocoon Nebula was shot through my still new 12.5 - inch Plane Wave CDK at f/8. This is a stack of 8 x 5-7 minute exposure, also a modified Canon 6D and IDAS LPS-V4 filter, shooting at ISO 6400. This object is a frequently underappreciated, complex emission and reflection nebula about 3,000 LY away in Cygnus, with much detail and color.

This is a stack of 8 images using my tired old Canon 450D set to 100 ISO and a full range of shutter durations to capture the prominence as well as the corona.

High Dynamic Range Stacking and processing. I hope to get more of the lunar surface detail and I explore blending multiple stacks.
