NGC 6946, the Fireworks Galaxy, with Esprit 120 & Canon 60Da

Here is a recent image of the Fireworks Galaxy taken from the St. Croix Observatory (SCO). NGC 6939 is in the upper left corner of the image.  If you scroll down the image blinks with an image I took several years ago revealing a supernova that was found in May, 2017. The older image was taken with an old Meade SNT and a Canon 350D. It clearly shows the improvements I've made in equipment and processing technique.

The supernova is marked with a white arrow
