Rosette Nebula Ha +OSC (Sh2-275 / NGC 2244)

The Rosette nebula is a stunning diffuse hydrogen cloud surrounding a open cluster of stars in the middle of the frame that formed from condensing of the hydrogen cloud.

Locate in the constellation of Monoceros, the nebula is about 5,000 light years from earth and measures approximately 130 light years in diameter.

I used the Ha data I gathered from SHO version ( https://www.astrobin.com/84rz2d/E/?nc=user ) 2 months prior and finally collected the OSC color data when a newish moon and clear night decided to coincide.

I used pixel math to combined the hydrogen layer and red layer to form an enhanced red layer. With so much data on the Ha layer, I also used it as a luminance layer. Always a challenge to find the right color saturation with the Ha+OSC, but I enjoyed the final results.

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.
