Here's a 90-second-long image of NGC 3155 (the Spindle Galaxy) that I captured remotely on 4/10/2013 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.
NGC 3115 is a tenth-magnitude, lenticular galaxy located in Sextans. It is seen edge-on and lies at a distance of approximately 32 million light years. NGC 3115 contains a supermassive black hole of some two billion solar masses.
