Seeing was bad, transparency was low. It was like imaging through gravy. Thanksgiving gravy. But it was the first remotely sunny day since I got my doublestack filter, so I had to get out and see the difference. These are the best images from the single and doublestack, for comparison. They were processed 100% identically (autostakkert, imppg, GregAlt's python script), so all of the differences are from the doublestack. The reflection glow in the background is pretty major, but wow the detail is fantastic! (Note, I did not adjust the first pressure tuner at all between images. I only installed the second, then adjusted it). I think the glow could be smoother with more detailed processing, or adjustments to the python script. This was done more to highlight the single/doublestack difference using identical methods.

I've already ordered an HRG to cut down on the reflection, and also need to play around with rotating the 2nd filter. Clouds rolled in before I could do much, unfortunately.

I've also added an animation of the area for the 3 larger sunspots.

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.
