The Rosette Nebula

Acquisition type:

The first time and last time I imaged the Rosette, I was in the first few months of the hobby and using the ASI183MC Pro. Not my best work as I didn't understand the amp glow issue and how to effectively calibrate it out.

I think I did better this time and using the ASI533MC helped too, lol no amp glow!

The Rosette Nebula and the open cluster NGC 2244 in the center. Just over 5,200 light years from Earth, in the constellation Monoceros.

Description: Since I used a quad band narrowband filter, this is a my quasi "SHO" version using Pixinsight to separate the channels and renaming for Sulfur II, Hydrogen Alpha, and Oxygen III. Then using PixelMath to recombine into a new image version. This was basically a learning process to do this type of post processing with Pixinsight. I have done this using Astropixel Processor but wanted to give this a try too.

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.
