Bill Brown caught this amazing shot of the Sadr Region in Cygnus, with his Stellarvue 130 Triplet. This diffuse emission nebula surrounds a star named Sadr, at the center of Cygnus’s Cross. Sadr itself is roughly 12 times the mass of our Sun and has an approximate magnitude of 2.2, Making the surrounding nebulous regions reasonably bright.


According to Bill: "Here is an image of a portion of the Sadr region in Cygnus I acquired using the Stellarvue 130T."
