M52

An amateur astronomer has published a new astrophotograph of NGC 7635, the Bubble Nebula, together with the open cluster M52 in Cassiopeia. The image was taken in HOO bicolor from 240 exposures of 60 seconds each in hydrogen-alpha and oxygen-III, using a SkyWatcher 254/1000 telescope, QHY163M camera and EQ6-R Pro mount with guiding. Astronomy communities are sharing the result as an example of what dedicated home equipment can capture.
