The Pinwheel galaxy (M101):

A 30 minute RGB rendition of this popular face on spiral galaxy in Ursa Major, some 21 million light years away. A companion dwarf galaxy NGC5474 can also be seen at the top of the frame. Imaged with an ASI533MM Pro camera using a Sky-Watcher 80 Esprit triplet refractor. Integration and processing done in Pixinsight. An additional 10 minutes of luminance data was also taken which was combined with the |RGB data used for the annotated image.



The Little Pinwheel galaxy (NGC 3184): 

A 2.3 hour LRGB/Ha composition of the Little Pinwheel Galaxy in the constellation Ursa Major some 40 million light-years away. Imaged with an ASI533MM Pro camera using a Sky-Watcher 80 Esprit triplet refractor. Integration and processing done in Pixinsight.
