Notes: Very difficult imaging this NGC object ... Started imaging at the beginning of this month when the moon was full, which produced a terrible background. Then varying amounts of high clouds moved in. Only had about three and one half clear (and moonless) nights. Ended up using 80 out of 154 subs on this image. See the 8" image.
