NGC 6188 The Dragons of Ara
This is a Telescope.Live SHO dataset from the El Sauce Observatory, Chile
Update:
I've reprocessed to provide less of a bicolor image with a bit more color range. The Sii and Oiii channels are very weak on this target, while Ha dominates. As a result, the image really 'wants" to be more monocolor than anything else so it takes some tweaking to get additional coloration and not have it look completely artificial.
The third revision is to crop the image to provide more emphasis to the Dragons. I hope you enjoy!!
There is another data set on this target that I will be posting shortly. It was acquired with a much longer focal length so it focus's on a much smaller region of this nebula. This has exagerrated the dominance of the Ha and diminished the Sii and Oiii further. You'll see that dataset posted shortly.
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.
This is another object that I've been looking forward to processing. I have to admit though that I'm not entirely satisfied with my results yet - for the Nebula itself. I haven't been able to get the color range that I feel is in the data. There is a strong tendency for this data to seem to shift toward a bi-color range between red and blue with little palette diferentian in between. That may be due to the relative shallowness of this dataset - it is only a little over 5 hours of integration. I suspect this is a target like IC443 that improves noticeably with additional integration time.
