This image was my first time using an electronic filter wheel, containing a 2" Optolong L-Ultimate and an Astronomik SII-CCD EOS Clip Filter mounted into a 2" holder. This shot is four hours of data.

Not really knowing what I was doing, and with a Youtube video or two open in the background, I experimented with running WBPP twice, once with the LU data and then with the SII data, before splitting the LU into Ha and OIII then merging with the SII. Or tried to, at least, the results were horrific (through no fault of PI). I then re-ran WBPP importing all the data in one go and played around with various combinations on the two autocropped images it gave me. With no real hope of success, I imported three finished (to my eyes at least) images (LU, SII, Stars) into Affinity Photo and saw this after blending all three together. I'm still a rank beginner with all this so have no inner sense of art to guide me yet, but it's pleasing to my eye. Only time will tell if I look back on this in a few years time and shudder or smile.

BTW - that combination of PI and Affinity is the bee's knees! Hiding and unhiding that SII layer shows just how little, and yet how much, it contributes to the overall image. It would be duller without it.

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.
