Description

FSQ 106 with .6x reducer and ASI 1600 mm cool pro. This was just an experiment to see if the highly touted FSQ optics could pull any detail out of this little jewel at a focal length of just 318mm. Conditions were very poor at times, and calibration did not work well for the Lum subs. Combined with the fact that this galaxy never rises higher than 38 degrees and is located in a nearby light dome, I didn't hold out much hope--especially with such limited data (for me).
