Kronberger 50 Hampshire Astronomical Group Picture of the Month, March 2020 Published in Astronomy Now Magazine April 2020
Kronberger 50 is a circular filamentary planetary nebula in the constellation Cepheus. This is by far the faintest target I have ever imaged. I can find no other images of it online, so I believe that this is the first time that it has been imaged in colour.
