The Rosette Nebula, catalogued as Caldwell 49, is a large emission nebula located in the Monoceros constellation. We find several single nebulas within the Rosette with rich star forming regions such as NGC2237, NGC2238, NGC2239 and NGC2246. We also find, in its center, the NGC2244 open cluster that was first discovered by John Flamsteed in 1690 and later confirmed by William Herschel in 1784. The nebula was first announced by the American comet hunter, Lewis Swift, who in 1886 distinguished a bright patch of nebulosity around the original open cluster (now catalogued as NGC2246). The nebula is located around 5.000 light years away from us and it spans for 130 light years in diameter. In the night sky it occupies a surface of more than 5 full moons. In this image we can distinguish several Bok globules. An opaque and dark spots all around its structure that are thought to be composed by molecular hydrogen (H2), carbon oxides, helium and some 1% of silicate dust. These small dark nebulae are the origin of new forming stars, typically in multiple-stars systems.

This image is the result of combining broad band filters (red, green and blue) with Halpha and OIII narrow band filters to enhance the strong hydrogen II and oxygen-III emissions from this nebula.

This final image is the first light of my new ASI1600MM-C PRO version. The RGB images have been enhanced with Ha and OIII in order to highlight the nebulae estructure while conserving stars size and colours.

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.
