First attempt at the Wizard Nebula. Historically I have gone for the same total integration time for all three SHO filters but I've been exploring the idea of aiming for equal signal to noise ratio for each of the three filters which requires different total integration times. I've been using SkyTools 4 to come up with a starting point and I figure I'll try to tweak my results from there.

Initial planning put the S : H : O ratio at 14 : 2 : 3 so I'm starting around there with the goal of over 24 hours of SII.

Also trying a different SHO post processing technique where the Ha (Green) channel is split between orange and blue via the curves tool in pixinsight. I'm getting a little more color variation than my previous method of desaturation of green with SCNR then overall saturation boost.

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.
