This image of the Rosette Nebula was taken in the backyard during January 2015.
Taken with the Pentax K10D DSLR with smc P-A* 1:4 300mm lens. An IDAS LPS P2 filter was used on the lens to improve contrast.
This is not a great picture, just OK. The upper right shows issues with framing and a green gradient due to DSS' mosaic process. The focus is soft across the whole field, largely due to operator error.
Eventually I'd like to get the camera back into the field to try a wide target like this again. Galaxy season is happening now and while it's fun to consider, I'm not sure if the DSLR would be sensitive enough to make much of the galactic light show. Would be worth a shot to get the whole Markarian Chain.
