We've been fortunate to have continual clear skies down here and I've really been able to pour it on for a couple of projects... I had every intention of going 100 hours on this target, but honestly I'm a little horseyed out and the last couple of nights of NIR didn't seem to add to quality of the data. I know this one is a little out there, but I'm going to have some fun with some palettes now that I'm using the NIR as I did with the Helix. Time to keep on exploring with NIR. I think the brown dust is where it seems to show the most difference... Maybe a psychadelic Running man next. The second half of my nights are open right now so I am all ears :)

For those interested, the color palette started off as:

Lum (.25Ha+NIR)
Red (NIR + G)
Green ( B + .3 HA)
Blue ( Ha-.7NIR)

Lots of color tweaking and fiddling probably destroyed much of the integrity of that mix.

As always, I love hearing your C&C's and thanks for looking!
