After hours of frustration with focus always looking fuzzy at best, swapping components, changing extension tube stack ups , checking colimation, etc. Colimation looked absolutely terrible. This just didn't seem right as weeks before I had the telescope about as well colimated as seemed possible.

I suspected tilt/misalignment and tried all sorts of parts/swaps trying to find it. I tried checking colimation with out the 2x Powermate, with it, with out it, and with it again. The first time without it it a star test still showed tilt. I put the 2x back in, still showed the same problem. Removed it again, and the star test showed colimation looked really, really good again. I put the 2x back in, and it looked just as good as without it. Something about the way the parts are settling when screwed together? The large 48mm SCT adapter (91mm length)? Something else?

As expected after I got the system back in alignment clouds began to form, and I only got 2 video recordings in before Jupiter/Saturn were clouded over.

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.
