NGC 2244 The Rosette Nebula in Monoceros in SHO

The open cluster NGC 2244 lies at the center of the nebula whcih lies about 5,000 light-years from Earth and measures roughly 130 light years in diameter. The Chandra X-ray Observatory revealed the presence of approximately 2500 young stars within the dense molecular cloud, including massive O-type stars which are primarily responsible for the ionized bubble.

The un-relenting cloud over the last month(s) temporarily lost the plot and I got one spectaular night with the SQM meter reading magnitude 20.6 per square arcsecond but it was obvious to the unaided eye it was a very good night indeed. Last night under a blazing full moon I had great seeing but very ordinary transparency but no complaints as I managed to get enough data to greatly improve the detail.

The RedCat 71 is a truly remarkable scope. On the AM5 I ended up with a total of 81 exposures (6.75 hours) and no rejects (!). I can carry the entire rig from the house to the backyard without ripping my aging back. Looks like (No Back) Strain Wave mounts have really come of age :-)

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.
