Just wondering if there was a simple libration calculator on the web, or a list of the times that we can see more of the polar regions of the moon, a little peak of whats round the corner so to speak :)

VMA does it...

We choose to image with DSLR’s. We choose to image with DSLR’s in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.

It shows you the libration of the moon but does not tell you when this is at it's greatest, maybe I'm asking to much I don't know.

Try this then...

Lunar Calculator User Guide 2.30

Theres a link to the software... $20 to register...

It seems to do quite a bit "un-registered" but limited to +/- 1 month from current date and has low res images set...

The CalSky website gives useful lunar information. Librations are given as angle of tilt and position angle. May be worth a look.

Mick, the floating arrow in the VMA shows where libration is favorable, but you need to look at the "Libration in Latitude/Longitude" numbers on the 'ephemeris' tab to see how favorable things actually are.

The numbers tell how many (negative) degrees over the limb we can see... the lower the number, the more favorable the libration. Best i've ever seen was almost -8. If you were looking for favorable libration predictions on specific features though, i'm not sure if the program does that or not.
