SH2-9 lurking behind dark molecular clouds.

Sh2-9, also called Gum 65 is combination emission and reflection nebula in the Scorpius constellation, surrounding the multiple star system Sigma Scorpii.
Although I has planned to visit a dark site for the LRGB data, Covid got in the way! (blah - back to bed soon!

)
So I've imaged this one entirely from suburban Melbourne, Australia. I've used lots of short subs, to mitigate the effects of LP, which appears to have worked ok!

I was surprised by how much dust is present in this region, which doesn't seem to show up on many other images, including on my own previous attempt. So I've worked hard to balance the LUM dust with the Ha signal.
It looks very 3D!

The new NoiseXterminator plugin sure came in handy as a result, and I'd highly recommend giving it a go.

C&C welcome as always!

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
