Aww man this looks wonderful, this region seems to be colourful no matter what the wavelength! How do you find infrared processing compared to optical? Have you ever done the Zeta Ophiuchi region?
Finally one more question, what is the mystical symbol in your avatar?

Re: Submissions: 2016 July
I find the process to be largely the same. The larger wavelengths seem to spread out a bit differently than the smaller wavelengths, so point sources seem a bit fuzzier, even though they aren't... how to put it? The point spread function is, uh, bigger. The PSF for WISE seems kind of soft. It would be tempting for a lot of people to slap a sharpening filter on them. And I still yearn for more coverage of the electromagnetic spectrum despite having four bands to work with. The jump between W2 and W3 is far too large. I would like a third band close to or between W3 and W4.starsurfer wrote:Aww man this looks wonderful, this region seems to be colourful no matter what the wavelength!

Noctilucent clouds in Estonia 14.07.2016
Copyright: Märt Varatu
Website: https://500px.com/maart Night clouds or noctilucent clouds are tenuous cloud-like phenomena that are the "ragged edge" of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight. They are made of ice crystals. Noctilucent roughly means night shining in Latin. They are most commonly observed in the summer months at latitudes between 50° and 70° north and south of the equator. They can be observed only when the Sun is below the horizon.
They are the highest clouds in Earth's atmosphere, located in the mesosphere at altitudes of around 76 to 85 kilometres (47 to 53 mi). They are normally too faint to be seen, and are visible only when illuminated by sunlight from below the horizon while the lower layers of the atmosphere are in the Earth's shadow. Noctilucent clouds are not fully understood and are a recently discovered meteorological phenomenon; there is no record of their observation before 1885.

Cosmic Emotions
As the moon reigned over her chariot, the horizon was red, fell in love with the nature and the stars shone even more!
Mars and Saturn dragged the dance, in Libra, in Ophiuchus and Scorpio and our Galaxy as a delusion shining in the firmament ...
Perhaps the most fabulous thing was to swim under the light of our galaxy and around you, in your touch, hundreds of blue Fluorescent Plankton lights illuminate ... how majestic is nature!
