Seyfert’s Sextet, found between Hercules and Serpens, consists of 5 galaxies and a long tail of stars of one of them. NGC 6027d is not gravitationally related and is actually 955 million LY away! The other 5 are only 190 million LY away. Such old photons!

The #Dwarf3 sensor nicely fits Kemble’s Cascade (Kemble 1), an asterism of about 20 stars in the constellation Camelopardalis. It starts from the upper right and ends at the open cluster, NGC 1502 at the lower left. A single 15 sec shot vs a 4.5 min stack.
