Lunar resolution calculator?

[Jannis]

I'm just curious how i can somehow calculate what my lunar resolution actually is?

As in, roughly how many meters 1 pixel resembles in pics like this: http://stargazerslounge.com/topic/212957-tonights-moon/

What I do is find a feature on the moon and check its size from a moon atlas then see how many pix on the image cover this feature. I have done a quick calculation looking at your shot using Geminus crater which is 86 km dia. Geminus is about 120 pix across on your image so 86 km divide by 120 pix = 0.7 km per pix.

Ah, nice. Thank you very much!

700 meters pr pixel is actually a bit highter resolution then i thought it would be. I think i should be happy with that for now atr least, and focuse more on increasing the detail level for my current resolution.
