Messier 101 - The Pinwheel Galaxy

Messier 101

Another attempt at capturing more details of the core. Dust lanes and arm band structure are visible all the way to the center. Outer reaches of the arms are present at far right of the frame. Never mind the amp noise at the lower right. This is 27 x 240 second frames stacked and calibrated with 5 Dark, 5 Flat and 5 Bias frames. Usual setup. Finished this up at 4:45am 4/13. - mb
