Spiral Galaxy NGC 5033

Here is an image of NGC 5033. It was made from several different data including a 2x2 bin on luminance. This lower resolution data had nice signal level and really didn't lose much over the 1x1 data. What was gained in signal level was useful to the image. Image looks like a soft focus, but I think it is the seeing. We seem to be struggling with seeing more often then it seems it has been in the past. A full size image and exposure / processing details are at:

hi Jim,

this is a nice result on a most difficult object!
this galaxy is so dim, I tried it only once with the one shot color at f/9 and I only saw a wee bit of the core region,...so I had to let go.
you did a good job on that toughy smile

clear skies, guys!

Yes, it is nice. I don't think you loose too much with 2x2. And good to see the progress from the earlier shot. But which one is backwards, as they seem to be mirror images of each other?
