M17 - Omega Nebula in HOO-RGB

Update 18 June 2018: added 46 minutes OIII data and reworked the entire dataset as HOO-RGB.

This is one of the first images acquired with my new ZWO ASI1600MM-C camera, coming from an old Canon 450D (XSi) DSLR. I still have some problems to sort out, but the experience has been great so far. Telescope and camera were controlled through APT with EQMod and PlateSolve2. It’s amazing how pure the colors are with RGB filters, even from a location with heavy light pollution. I used the NBRGBCombination script in PixInsight to blend the Ha data with the RGB.

The Omega Nebula (M17) is a dense cloud of gas and dust, lit up by bright young stars. A bit like the well-known Orion Nebula but 4 times farther away from us, at a distance of about 5500 light years. This DSO is also commonly referred to as the Swan Nebula, a name that is derived from its visual appearance: the brightest part looks like a swan sitting on water, tilted 45° and looking to the top left.

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.
