The Whirlpool Galaxy in Canes Venatici
with 10" f/3.9 Astrograph
Uploaded 4/15/18

 
This
            is the deepest image so far I have taken with the 10 inch of
            this enigmatic interacting galaxy. Star sprays from the interaction
            go well beyond the normal short exposure images seen in publication.
