Object name: NGC7790
Designation(s): NGC7790, BERKELEY58,
There is a line of open clusters in Cassiopeia that's far longer than my field of view allows. Here I've picked up the two furthest east, NGC 7790 and Berkeley 58 (upper right to lower left). All may be closely related. I imaged NGC 7790 and NGC 7788 back in 2011. The others further north and west are still to be taken. Those are Frolov 1, Harvard 21 and King 12. Only King 12 is really recognizable as a cluster from the rich Milky Way background.
