Hello everyone
my weather has co-operated and allowed me to add 6 hours of Ha.
This is the first time I have ever tried to combine pure Ha into a galaxy image. I tried a couple of techniques to isolate the Ha data and finally achieved it (I think) but there has to be a quicker way. I tried Chris Schur's approach, but could not get that to work at all.
So here is the link to the full frame image (2mb)

and for a nice comparison methinks, here is a mouseover page.

I have downsized the images to 1280x 880 for this comparison, so they should fit nicely on a monitor set at that resolution. Just center up the galaxy on your screen then hover your mouse over the image to load the enhanced version.
thanks as always
Martin
