We streched the image hard to make also the outer dust band visible, therefore the image appears a little noisy. The group of small galaxies north of the galaxy is just an extra bonus. 

The extreme tracking performance of this telescope allowed to track the telescope blind without any tracking corrections for 2m integration times. After a better polar alignment maybe 10m will be possible.
