Sh2-115 and Abell 71

Shot over 6 weeks during the shortest nights of the year, this target ended up being the July Challenge object on CloudyNights--lucky me to get a jump on it with so little darkness to work with.

I had an opportunity to have a personalized learning exchange with Adam Block, trying to save some Sii data using his Selective Rejection technique that just wasn't working as expected. We/he came up with an explanation and a solution. He said he might update his material on this really useful process to include the issue I found and he resolved. A tip of the hat to Adam.

I also found that my wallet will be a bit lighter, as using a trial version of StarXterminator gave a far superior result to using StarNet2 on this data. I will have all three of Russell's Xs in my tool kit now. I find them simply amazing tools.

I am never quite sure how hard to push stretching and colours in narrowband images. Hope I haven't crossed any lines here, but I kind of like it the way it is. Usually I start a bit more subdued in brightness and saturation and gradually build it up. Might have gone a bit much on this? I do like using RGB stars, but again it is a taste-thing about how much/many/prominent in terms of brightness, size and saturation. I haven't done enough of this to have my preferences settled.

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.
