Supernova remnant

This
            expanding bubble is set aglow by its impact with the surrounding
            nebulosity. This is the first deep sky shot with the 10 inch
            and the Nexus coma corrector, yeilding f/2.92 and pinpoint stars
            to the corners of the frame. Exposure was only 90 mins, but through
            an Optolong E-Enhance filter.
