Here's an image I did a few nights ago to try out my new Multi-Purpose Coma Corrector from Baader Planetarium. The weather hasn't been good at all, this image was taken in a clear spot between the clouds with the Moon rising.
The MPCC works a treat and it looks like it has removed the coma in my GSO 12-inch across the entire field ! It screws into my 2-inch eyepieces and also directly onto the front of the t-adapter for the Digital SLR.
The image of M42 is 4 exposures @ISO200 totalling about 9.3 minutes and covers about 49 x 33 arc-minutes.
The first image I attached in the natural looking image, the second image has an un-sharp mask to highlight certain details.
Here's a higher resolution version

And the image which is un-sharp masked

Hope you like the images!
