This 45-second-long image of the SAB(rs)cd spiral galaxy NGC 6946 (Arp 29) on the Cepheus-Cygnus border was captured remotely on 2012/6/26 using the Bradford Robotic Telescope's 14" f/11 Celestron C14 SCT and FLI MicroLine camera located on Tenerife in the Canary Islands. A Celestron focal reducer yielding an effective focal length of 1877mm at f/5.3 was employed.
