Description

Data on this target gathered over many nights. By the time it was dark enough to image, the galaxy was right at the point of the meridian flip, and after that it started to sink into the neighbouring conifer hedge, but little by little around 18 hours of exposures were gathered. Around 10 with the Luminance filter and the rest split on the RGB. A little data added in from a OSC version of the 460ex that I acquired near the end of the project.
