NGC 2244 Rosette Nebula 2 Panel Mosaic in HO

Revision title: Dialed up the detail

Well, next time I'll plan better for a mosaic. This started out as a Rosette Core then I decided to expand to a Mosaic. I have three frames done, and three frames to go, but the sky position NGC 2244 is no longer favorable for good light frames at high altitude. So, a reminder is set for next December to finish this one up.

This is my first attempt at a very high resolution mosaic using the CDK20 and the AC4040 camera and I'll say the two frame alignment process went very well. Planning a mosaic with a rotator to get good overlap and pick a good bright guide star for the adaptive optics is more than a simple exercise, but fortunately the field of the Rosette Nebula has many bright stars.

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.
