๐Ÿ“ธ NGC 6946 and NGC 6939
This deep-sky image shows two cosmic neighbors in Cepheus: open star cluster NGC 6939 at 5,600 light-years and spiral galaxy NGC 6946, The Fireworks Galaxy, at 22 million light-years. Over 68 hours of exposure reveal stunning detail and faint dust lanes.

My grandpa captured the Fireworks Galaxy in the middle of May and got almost 5 hours on it! The Fireworks Galaxy is located on the border between the constellations Cepheus and Cygnus. It is a bright, colorful galaxy with a yellowish core, large clusters of blue stars, and many Ha regions (which aren't shown in this image). It's called the 'Fireworks' Galaxy because 10 supernovae have been observed in it over the past century.
