NGC 4945 and surrounds..

Here is a pretty average pic of NGC 4945 and surrounding area. 25 frames @ ISO400 each 100s, bias, darks and flats applied. I think I may have induced some unwanted noise as I forgot to take the flats when the camera was still attached so its orientation may be off slightly..unguided. I think atmospheric seeing had a lot to do with the average images I was getting, as we had storms later that night and the air was pretty unstable. Some shots may have had cloud in them too. I did however manage to pull in a few 15th mag galaxies around 4945 which is good. I would like to try a longer exposure of this object as I feel it has alot more to show us. Pic is 80% cropped due to stacking rubbish on edges. Taken with a canon 400D and Berts 80mm ED refractor @ 450mm FL.
