The Pinwheel Galaxy, M101, NGC 4547 was discovered in 1781. The observation was subsequently passed onto Messier who confirmed it's position and was one of his final additions to the catalogue. Estimated to be approx 70% larger than our own galaxy at a distance of 21 Million light years. I am happy with this capture of 3 hours 20 minutes in 20 minute sub exposures. calibrated in Maxim DL and processed in photoshop. Ha regions can be seen and I am very pleased with the detail all the way to the core of this beautiful showpiece galaxy.
