Rosette Nebula
Emission nebula in the constellation Monoceros

This is a hydrogen star-forming region about 5000 light years away. It's huge - over twice the diameter of the full moon. The bright stars in the middle are young offspring of the nebula. The intense radiation from these stars is like a wind blowing the matter of the nebula away, leaving the hole in the middle.

I've photographed this before, in January of 2018. This is a significant improvement over my previous effort. I managed to get 4 hours of good data - pretty darned good considering the recent weather in New York state!

I'm also having good results with the ZWO ASI294MC-Pro camera now - it's taken me a while to get used to it. While it's more light-sensitive than the Canon 550D, I don't think it's as color-sensitive, so my processing skills have had to improve to compensate.

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.
