NGC1365 and Fornax Group 43 hours

I have been collecting data on this target for what seems like an eternity. Although there is lots of data collected I feel the Luminance could do with some more data. I had to do a little smoothing to the Luminance channel to control the errant noise in the darker areas.

Lum 19 x 30 minutes = 9.5 hours
Ha 34 x 30 minutes = 17 hours
Red 16 x 20 minutes = 5.333 hours
Green 14 x 20 minutes = 4.666 hours
Blue 16 x 20 minutes. = 5.333 hours

Of note is the reddish background to the right of the image. This showed up in the red, Ha and luminance channels. Since there is no light source in the area I am thinking it is meant to be there. I do wonder though if it was some high cloud passing through. However, given that each channel was captured on different nights I am inclined to think this is some intervening gas in between. Although I could be completely wrong. I just don't know.

I am not sure if I like the way the image looks, I spent a lot of hours processing it and trying to achieve a nice balance.

What I really like about the image is the amount of galaxies captured within the field. Nearly every where you look you can see lots of galaxies. Given the size of the aperture I am pleased at what has been captured.
