Caldwell 49, Rosette Nebula

Today we bring you the Rosette Nebula! This is a picture we captured in March 2017 and didn't have time to process until now.

The Rosette Nebula is dense with hydrogen, hence the redness to most of the photo. All of that hydrogen is pretty active, stirring up and creating lots of new stars (about 2500) in this region. Those bright ones in the middle, they are large O-type stars that are much larger than our own Sun, and their radiation is exciting all the atoms there and making that hydrogen glow.

We love all the details here in this nebula, especially those little tendrils coming out from the middle of the donut, and the wispy waves of nebulosity at the top. We're also particularly happy with all those great star colors you see outside the nebula as well. It's proving our move into CCD astrophotography has helped to produce much higher quality photos than we've ever done before, even with such a short exposure time.

Please enjoy our first photo of 2017! And let us know if you have any questions or comments, of astronomical or technical nature, and we'll be sure to get those answered.

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.
