The Grus Triplet

[Russ.Carpenter]

Here is the Grus Triplet, which I imaged with a 27 inch Planewave telescope in Siding Springs, Australia. 1.2 hours of total imaging time, divided equally among R, G and B, binned 1X1. I used a synthetic luminance and the method described by Ivo in December, 2014.
StarTools continues to keep me humble. I’ve done quite a lot of comparative processing with PixInsight, Photoshop and StarTools. When I get it right, StarTools is always the champion. For me, the hardest part in StarTools is always at the front end—coaxing Autodev and Wipe to play together nicely. After that, it all falls into place.

That's really, really nice! Lots of other faint fuzzies to see too.
Only a nitpick, but did you suppress the blue much? I would expect a slightly bluer outer rim and more blue foreground stars...

Hi Ivo,

Thanks for the encouraging words. You're right about the blue. Color balance is still a learning experience for me. I need to remember what you have said many times: the acid test is the distribution of colors among the stars.
