Description

Another one I will not be able to finish due to the weather and the Moon.  I managed to get a decent red channel and a fairly deep Ha.  Version A is the red channel with Ha and version B is a mouseover without the Ha. I had not known how much Ha was in this galaxy.  Examples on Astrobin are not particularily clear. There is more than I expected; however, I did collect 17 1/4 hours worth, which is excessive.  Most was collected during a full Moon, though, so its hard to judge.  I call this the speckled core galaxy due to the speckled nataure of the Ha in the core region.

I think it would be better if the mouse-over function worked on the image once it has been cluicked on and enlarged.  If that is possible, I was not able to figure out how to do it.
