LGB taken 12-3-19 and Ha data taken Jan and Feb of 2016. I had taken some R data on 12-3 but gradients were terrible. One of the benefits from hurricane Michael was the removal of some trees that block sky access, but those same trees also blocked street light glare on my scope when shooting low to the NE. By trying to minimize color extinction for my colored filters I imaged R,G and B in that order when imaging in the Eastern sky. Try as I might, I could not salvage the R channel from the bad gradients for an RGB combination. I decided to use some Ha data taken in 2016 for the R channel. The camera orientation was almost 90 degrees different from my session on 12-3-19 and I was also imaging in the Western sky. Normal processing was done for both sets of images including alignment to create master images. An additional alignment process had to be done to align the images of severe orientation differences. In PI I used the dynamic alignment process on the master images to achieve the aligning of images taken in 2016 and 2019. The resulting master images had to be cropped substantially prior to final channel combination using Pixel Math in PI.

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.
