NGC 6188 The Dragons of Ara
This is a Telescope.Live SHO dataset from the El Sauce Observatory, Chile
This was acquired with the Planewave CDK24 telescope (approximately 4000mm focal length), so the FoV is much smaller than the version I posted earlier from the CHI-6 OTA a the El Sauce Observatory). The Ha dominates this emission nebula with only extremely faint signal available from the Sii and Oiii channels. Ha so dominated the dataset that I wasn't sure I was going to be able a useable color spectrum from that didn't look like some flavor of monochrome. I am impressed once again by the quality of the data acquired with the Planewave CDK24 OTA, it really is amazing.
Enjoy the image an feel free to compare to the previous "Dragons of Ara" that I posted previously. I have posted a new revision of that image where I've tweaked it a bit to make it appear less bicolor.
Update
Based on some discussion with Uwe Deutermann in the comments, I went back and applied BXT a second time, this time on the 'finished' starless image. I then ran the DarkStructureEnhance Script and performed a final tweak with the Unsharpmask tool. I tried not to over do it with the UnsharpMask since it can become very aggressive. The original and the 'tweaked' verson are both here for those that wish to compare.
Enjoy!!!
From Wikipedia:
NGC 6188 is an
emission nebula located about 4,000
light years away in the
constellationAra. The bright
open clusterNGC 6193, visible to the naked eye, is responsible for a region of reflection nebulosity within NGC 6188.NGC 6188 is a star forming nebula, and is sculpted by the massive, young stars that have recently formed there – some are only a few million years old. This spark of formation was probably caused when the last batch of stars went supernova.
