A couple of widefield shots

Hi everyone
these two images are a little silly really, given the image scale and field of view.

The first is a 4deg x 4deg view with M95 and M96 on center. There are literally loads of other background galaxies and M105/M106 are in there too. I love the little face on spiral right at the bottom of the image field.

This is LRGB 4.5:2:2:2 hours (SBIG STX), and the luminance was the subject of my "extreme gradient removal" demo at AIC this year.

The second is the Cocoon nebula; again, the image scale is no good for detail in the nebula itself, but I love the way this appears to have spun through space, leaving a trail behind it, before coming to a stop. That's what I was going after but what I didnt expect is the abundance of hydrogen in the background, and the Ha frames were full of it.

This is L (Ha+R)RGB of 7.5:2:2:2 hours (FLI Proline 16803). There are 2 mag 15 galaxies in the lower right of the image, but they are a little obscured.

My weather has closed in for a good while now, so its back to reprocessing.

thanks for looking
cheers
Martin
