M97 - the Owl Nebula

These data were on my disk since last spring. I did several attempts to process them, but never achieved anything reasonable whether I used RGB on its own or trying to play with SHO. The data itself looks ok but the processing is a real challenge. So dried out for fresh data owing to winter fog, I tried once more. The basic strategy this time was to base in on LRGB, boost Red by Ha and SII (both corrected for broad band flux), and the Blue and Green with O3. Lum was also boosted by O3 (which was essential to get the outer ring). So it kind of worked, at least I am happy with it as a first try, but for sure this is an object one has to come back to, proecssing wise and also with additional data.

Data were taken on March 21,22,23,24, and 25.

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.
