NGC 7129 in Cepheus

July 23, 2018

 

 

NGC 7129 is an open cluster, but longer exposures will reveal the associated reflection nebula  in the center. Dark nebula LBN 497 can also be seen. A lot of star birth activity is taking place in this area. A surprise target, and one of my favorite so far, due to it's shape and lovely color variations.
