Rosette Nebula

This was not planned and I have not imaged the Rosette since I started with astrophoto seven years ago, but when I after midnight realized that the object I was about to image had fallen below my southern obsy wall, I had to find something else quickly and thought why not see what the RASA8 - ASI2600MC combo could do with this iconic nebula. Nowadays I usually aim at faint and less well known objects, and compared to these, processing the Rosette was just so much easier with an enormous amount of signal. So about 3 hours of data at f/2 seemed enough. Although I had the NBZ dual-band NB filter on I could actually see the nebula live in its full glory on my laptop in my one-second exposures during the focusing and framing.

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.
