NGC6072 NB-RGB

This is one that nearly didn't make it. I really struggled to get some half-decent image together in large part due to have to use short exposures as the system in Namibia wasn't working very well. The main issue was adding the NB signal into the RGB image and nothing was working right out of the box, somehow. Eventually I simply added the H-alpha and OIII signal straight into the R and G/B frames without any further ado. That seemed to do the trick. Also, getting the right star colour correction wasn't easy either and I had to manually balance the R and B channels. Plus several hours correcting field uniformity and noisy artifacts all over the place. In the end this is what I came up with. A nice example of butterfly PN.

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.
