Cassiopeia

The constellation Casiopeia with many obvious deep space objects.

My main mount is still not up to speed for long exposure tracking, but I decided to break out the Vixen Polarie and shoot the 35mm lens just so I could shoot something.  I shot at wide open f/1.4, so there is some coma and blurring in the corners, but that stopped me from getting spikes on the stars and allowed 30 second exposures at ISO 400.  I shot a total of 625 exposures, but a lot of that had extreme light pollution from the east horizon at the beginning of the shoot and the west horizon at the end.  I got the best results by just stacking the best 240 from the middle of the night when Cassiopeia was almost directly overhead.  You can easily see the Heart and Soul Nebulae, the PacMan Nebula, and the Double Cluster, as well as other deep space objects.  Don’t just look at this one full screen, zoom it to full size or larger.  Located in the outer edge of the Milky Way, the number of tiny stars in this frame is amazing!
