PGC 69457 is a galaxy in the constellation of Pegasus. It lies at a distance of ~400 million light-years.It is well known because the quasar Q2237+030 lies directly behind it, at a distance os about 8 billion light-years. While gravitationally lensed light sources are often shaped into an Einstein ring, due to the elongated shape of PGC 69457 and the quasar being off-centre, the images form a cross-shape. However, the shape cannot be resolved on these images.The images comprises 5 x Luminance (180 seconds each), 0.5m f/2.9 ASA Astrograph with FLI ML3200 camera at an altitude of 60 degrees on 26 July 2017. The fields of view are 34’ x 23’ and 18' x 12', respectively.
