Antenna Galaxies added data

I have added extra LRGB data to this image. Its now around 16 hours or so.
Tricky to process but I am happy with the result.

After seeing M & T's superb image it reminded me I have never taken a decent image of this one. It is quite a dim object and fairly small.

I have done 2 nights on this. The first night's data was only partly used as it wasn't in focus enough. Also I think flats may help this data. There seems to be very little vignetting so I haven't bothered so far but processing this seem to leave a slight large red hot spot which took a bit to remove.

But last nights was accurate. I probably will do another night on this one as its still a bit noisy. Its 8 hours and 20 minutes so far. I have some Ha I may add as well if its good enough.

ASI183mm Pro and AP RHA 305 F3.8.
