THE ROSE OF THE UNIVERSE
- Rosetta Nebula Sh2-275
- Deepsky 250mm LRGBHOO
- Constellation Monoceros

Old data from 2022 reprocessed with current knowledge of image processing. Distorted version, LRGB combined with DuoNB, stars in RGB.

The Rosette Nebula is a diffuse emission nebula with an embedded open star cluster in the constellation Unicorn. The nebula, which is also known as the “Harp Cluster”, is around 9100 light years away from us - it can be found in the night sky a good distance to the left of the Orion Nebula in the Milky Way band. The nebula got its name from its appearance, which is reminiscent of the calyx of a rose. In the center of the object is the open star cluster NGC 2244, a collection of luminous stars of the O and B type, which are spread over an area of about 40' diameter. In my opinion, a much more appropriate name for the nebula would be “The Rose of the Universe” :-)

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.
