What lives at the heart of the velvety rose? With the heat and the clouds (and those damned native drums), just two hours each in H-alpha (yellow) and OIII (blue), at a toasty -25C because that was as cold as the camera would go. Lost three subs to cloud. But for all that, the seeing was pretty good and the image is quite sharp in parts.
Big one here.
For one who once thought about being an anaesthetist, this looks very reminiscent indeed of the view of the vocal cords (toward the top) and the dark trachea beyond, seen during intubation. A happy, reassuring sight. If not, it's a worm-hole leading to somewhere interesting.
Toward 9 o'clock is a series of gargoyles in blackest dust, showing sharp edges, and being eroded by the brilliant light from the cluster.
Above them, toward 10 o'clock, is a set of shock fronts like metallic gold.
The most memorable dust lane forms and upside-down Y or wish-bone at 6 o'clock.
Toward 3 o'clock is a completely different set of shock fronts, bright in OIII, a angry blue-ringed octopus perhaps. Some shocks are very thin and fine, and intensely ultramarine, adding to the general opal-like effect.
There are some hot pixels and other bright artefacts about - as mentioned, camera temperature control was not so good, and the darks don't properly match. They can be easily rejected statistically when we get more clear sky.
