Tonight succeeded with nine comets for photometry. Bonus image of M81 and M82 (only 50 mins) below.
1° C and ice on the powerbank and parts of the power cable frozen to the roof. The anti-dew heater kept the lens dew-free.
The whole plan ran for 11 hours.

I don't see how this photometry says there's a rotational light curve signal. It looks pretty damn consistent with flat with the binned data

The observing plan from tonight is finished. Had to skip the first comet due to clouds but succeeded with the remaining eight. And the pretty picture also came out splendid. 50 mins of the Horsehead Nebula. Now off to process the comet data in Tycho Tracker for photometry.

The Ks photometry is interesting because of the deep methane absorption at 2.3 microns, I'm not sure about the z-band analysis. I don't know much of methane absorption there. I think it's the 2.3 microns that's saying there isn't much methane or at least there isn't as big of a drop as Eris/Makemake

In 2021 it brightened by about a magnitude out of nowhere.
Multi-year photometry through 2025 shows that extra light faded exponentially over ~1.4 years.
By 2024-25 it was basically back to the old level, though there are still signs of low-level residual activity.

The real first light for the S50 Pro: The plan for tonight has 9 comets for photometry and one pretty picture. There will be some wind, so I hope dew won't be an issue at predicted 3° C.
Still need to find out about the quality of this unit as the test images showed slightly elongated stars.
