M17 Swan in SHO with RGB stars added in

Revision title: complete reprocess

Some decent clear nights on the run allowed me to get around 23 hours of SHO and another 2Hours of RGB for stars.

I started with my normal 300s at unity gain, but felt was blowing out core of nebula so dropped back to Zero gain and 240s exposures. The RGB was also at zero gain but 90s.

Stacked into separate channels in APP and combiend then in both APP and startools with later blending and furtehr processing in PS using StarXterminator to produce starless versions for tweaking and to pull Stars from the RGB layer for blending in via screem mode.

Not entirely happy with the quality here for the time invested. Might try again later binning to 2x2 as I think seeing just isnt up to the full res here.

Anyway here it is warts and all :-)

Description: flipped the palette on this starting with HSO over SHO previous and running 2x2 bin in Startools to improve S/N. Cant recall what Startools preset I ended up with that gave this colouration but like it and tweaked to taste. Subsequent processing in PS as starless and re-adding RGB stars as before.

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.
