NGC55 17.5 hours

I started collecting data for this galaxy about a month ago. I have in fact collected over 30 hours of data but rejected all but 17.5 hours because of the rotation issue of the image. For some reason some nights at the time of the meridian flip the rotator rotates 3 degrees more than it should. It is not consistent and it presents another bug hunt I need to conduct.

The subs were 30 minutes for the luminance (I learned my lesson from NGC300 where I used 20 minute subs). The colour subs were 20 minutes each. So 510 minutes for Lum and 3 hours each on the colour.

I think I could have done with another 10 hours of Lum data, but I want to change my filters over to the Astrodons I bought. I might consider getting some Ha data though, as this galaxy has a heap of Ha regions.
