SH2-275 Rosette Nebula, RGB blended Ha Oii

What a fantastically beautiful area to image. There are so many great versions posted this year. In my attempt, I wanted to be dramatic (as usual), and show off the faint structures around the core and then the structures around the outside. I tried many iterations, RGB, SHO, HOO and finally settled on RGB with Ha blended into the red and Oiii blended into the blue. The Ha brought out the surrounding nebulosity. I then had to decide if to use luminance as the RGB blend was pretty good. Again, after many iterations I settled on using the Ha as luminance. I did not use any star reduction with BXT or any other star reduction method. I think I could bring out more of the faint structures around the core if I created an Ha + Sii luminance, but for now that is a bit above my pay grade and available processing time. Got to draw a line in the sand and post. I'm very pleased with the result from Bortle 7. -john

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.
