GH6 Full Moon HHHR (tripod) HR vs Preserve Details 2.0

I like HHHR first

All shots from tripod as it was windy tonight

Yes, HHHR the best - only one to clearly show the Alpine Vally E. of Plato, and Schroter's Valley adjacent to Aristarchus. I suspect that the HHHR was best because of the wind effect on the tripod/lens. The granular effect of the smooth background is a bit distracting, though, and has been seen on past lunar shots (but worse) in HR mode - from a E-M-III, IIRC. I'm looking forward to trying it on a partial lunar phase with craters on the shadow line in sharp relief and much more detail possible.

How did the HHHR turn out better than HR if there are both on a tripod?

Apparently, HR and HHHR work differently. In my test cases, tripod HR will generate a somewhat better image than HHHR (less aliasing and noise).

Because it was windy and HHHR has IBIS and the other doesn’t

FWIW: it is possible to shoot HHHR with IBIS off, but a quick message appears saying to turn the stabilization on.

I am really liking the results that I am getting from GH6 HR and HHHR.

WoW

HHHR probably takes less time than tripod HR.  For completely static subjects I expect tripod HR to be better.  But the moon is not as static as one may think.  Point with a good zoom to the moon sometime on a tripod, go away for 30 seconds-60 seconds and see how much the moon already moved off frame!

FYI:

HHHR takes 16 sec, tripod HR takes 9 sec, approximately (1/800 sec).

HHHR takes 16 shots and selects 8 best, HR takes probably 8 shots.

I'm seeing a weird noise pattern in all the lmages at 1:1. Oversharpened perhaps?

I don't think that's noise or over-sharpening, esp. @ ISO 100, but the response to the absence of repeatable detail in the 8 frames with the nearly full moon, where surface detail is the least. My take is that the processing algorithm, since it can't just leave a hole there, just fills it with this pattern.

Where there is some shadow/crater detail in the SE rim area, you don't see it. I've seen that in another ~ full moon HR image, where it was more striking and  linear. And in this image, it does take on a linear pattern in some areas...

Are you talking about 16 second to take the shots or 16 seconds to go end to end with the processing? Because the processing of the shots is not the same time it takes to take the shots.

Finally on the HHHR shots it's quite possible it aligns some shots with the moon more shifted and by the registration process effectively "shift it back."

It is the total time from shutter press to the end of the assembly. The time from shutter press to start of computation is always less than a second in my test (1/800 sec shutter speed, sensor readout speed is likely the limiting factor).
