Sharpless 202

Image Details:

Sharpless 202 is a lesser-photographed object with respect to Heart and Soul nebulae which are located just outside the field of view in this photo. I picked this comparatively dimmer target out of a desire to take a break from brighter ones - and to show that you can point a camera just about anywhere upwards and find some nebulosity.
