imaged NGC 6621 and 6622 (Halifax)

NGC 6621 and 6622 are interacting galaxies. We had viewed them briefly from Glendo but I wanted to revisit. aka Arp 81. In Draco. Thanks to BGO, we can enjoy the spectacle. Love the arch at the north swooping into the galaxy to the south.

The small round fuzzy galaxy LEDA 2714451 is visible to the south-west, below the equilateral triangle of stars.
