Omega Nebula M17 skirting the rooftops - modified SHO palette

Revision title: SHO with HSO stars - reprocessed from scratch in Pixinsight with NSG and x2 drizzle

Can't get any lower than this to the South from my backyard, 20 degrees at meridian. Darkness is in short supply this tie of year but pop the reducer on there and some narrow-band on an object I've never imaged before seemed appropriate.

The horrendous weather in mainland Europe is partly due to the high pressure that's sat over the UK and given us very un-UK like conditions. Imaging 4 nights in a row is really unusual and the forecast looks like more may be possible as the high pressure doesn't look as though it's going anywhere for a while. Hope all are doing OK with their current conditions.

A couple of rather serious spinal problems make setting up my full rig less than straightforward at the moment as I shouldn't carry anything too heavy prior to surgeries. However a forecast for a few clear nights in a row has proven too tempting to resist! I've taken steps to lessen the load on my spine and additional workarounds are in progress.....

Title: SHO with HSO stars - reprocessed from scratch in Pixinsight with NSG and x2 drizzle

Description: Yet another image in my gallery that kept bugging me to fix it every time I saw it! The choice to drizzle this one is a bit debateable as there weren't enough subs in each channel to do a good job. It might be one reason why there is a subtle patterning in the background. It's not perfect buy way better than the last version so I'm not complaining. I also gave the color-corrected HDRMT script a try to help tame the brightest bit in the nebula - seemed to do the job.

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.
