Description

Some experimentation for this one.  (well aren't all our images experimentations?)   I captured luminance with my mono 2600MM and RGB with my OSC 2600MC.  Why?  well with lots of clouds in and out I figured I could get same data for RGB channels that way.  I ended up integrating the mono luminance with the RGB luminance extract (using APP).  Then with BXT, I used only 0.1 star sharpening and at the end used Bill Blanshan's star reduction V3 with 3 as mode.   I am pleased with the stars.  I had lots of moonlight gradients which GraXpert mostly took care of...along with an aggressive black point. 

There have been so many great images of this these galaxies lately that I almost didn't post as I didn't think it lived up to my expectations.  But thinking about it more, heck this is fantastic image from a B7 backyard.  Think about it, NGC3718 is 52MLYs away.   BXT did bring out good detail...even can see the arms on the galaxy PGC 35620 (part of the Hickson group 56 or ARP 322  at ~425MLYs, what a mess of a group.  I wonder if there is enough time for advanced life to evolve in these chaotic collisions.).  Fantastic what we are doing.

Description: black point too low. The image did look better, not as dark, on my monitor than the upload.
