Rosette Nebula OSC

The Rosette Nebula also known as Caldwell 49. This beautiful nebula seen in Monoceros is the subject of my latest project using my OSC camera and dual NB filters. The Optolong L-Ultimate Ha/Oiii and Antlia ALP-T Sii/Hbeta filters for this image. Stars are from a small amount of data through my UVIR filter. I tried a different approach for combining the data from each filter in this image. I referenced my filter bandpass curves to my camera's QE curve and estimated the percentage of R,G,and B data collected by the sensor at those specific wavelengths. I then split the RGB channels from each filter integration. I made Pixel Math equations to recombine the data into new RGB channels based on the percentages from the filter and QE curves. This is very different from other methods suggesting to split the RGB channels into Ha, Sii, Oiii, and Hb with the Oiii and Hb combining both the blue and green channels from their respective filters.

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.
