Revision title: C49 Rosette Nebula update

The Rosette nebula is a beautiful and impressively large DSO.

Only a couple of hours of clear sky and I had to wait a while before this target was well above the trees of my neighbours backyard..!

Just 17 x 180 sec of usable light frames, which is far too little for a quality stack, hence the noise. But I am still pleased with the end result. I shot this image with a dual (Ha/Oiii) narrow band filter. In postprocessing I extracted the Ha and Oiii channels and reassigned them to R and G&B respectively in a RGB composite. I applied this technique for the very first time and used Astro Pixel Processor (APP).

Many thanks to Nico Augustin for his video tutorial: https://m.youtube.com/watch?v=j5XgZ3odKx8&feature=youtu.be

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.
