Here we have a look at M101 - The Pinwheel Galaxy.
I have tried this twice before and not really achieved the results I wanted.
The new AP 305 set up I am part of over at DSW has been busy collecting some data on this so here is my first real attempt processing an image from it. The detail is pretty awesome keeping it simple, even more so as a lot of this data was test data (hence the cropping). The stars are harder to manage but that is the characteristics of the scope. Extra detail available but not quite so sharp on the stars. I am happy with this trade off as some super detail is available and the scope was able to go a little deeper than your average bit of kit showing some of the outer arms very nicely.
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy distanced 21 million light-years away from earth in the constellation Ursa Major. First discovered by Pierre Méchain on March 27, 1781, it was communicated to Charles Messier who verified its position for inclusion in the Messier Catalogue as one of its final entries.
Comparable in size to the Milky Way. With a diameter of 170,000 light-years, it is roughly equal the size of the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small central bulge of about 3 billion solar masses.
