A very nice image indeed Martin.
And you have SN 2011ja nicely in your image. Hope you don't mind me cropping, rotating, nagative and arrowing your image to show the SN. As there is still a lot of interest in this you could send your image for posting on Dave Bishops site below. http://www.rochesterastronomy.org/snimages/

Observing the acquisition of this image and the Leo triplet over a night illustrated the complexities and attention to detail required for this type of imaging. An eye opener. A technological feat.
