At the end of the superb period of astrophotography weather towards the end of March 2012 I captured 3.5 hours of data on this wonderful spiral galaxy.

After a summer of record rainfall it is hard to remeber the wonderful imaging conditions we had earlier in the year.

The central region of this galaxy is extremely bright and resembles whipped cream. The strong signal allows aggressive sharpening, whilst a softer approach on the outer halo is needed.

I note now this was the last image I took using the Meade motors on the homemade telescope mount before I built my own system

68x180s exposures on my 8inch newtonian and a 285 chipped mono camera.
