Still working on the prize of a missing toenail which keeps me from GSSP.
Last two nights the marine layer has rolled in at 1 AM, stopping any further imaging effort. At least I can add a few more darks to the library.
Interestingly, I've seen that the RA drift continues. The mount runs slow - about 9 arcseconds per hour of drift. This is the same pre and post meridian flip -- in the same direction. No real variation due to gravity or the guiding settings.
It's down to hardware again. I am swapping the RA cable with another one that I have in the hopes that it might be a resistance, crosstalk, or communication issue with the Gemini or the encoder. If this does not save it, then I'll start learning the Gemini 1. I'll swap the computer and build a quick model to try to make it work.
Here's what the M16 looks like now with 27 subs:
