Thanks Alan, I`ve had a quick look at the Atlas. I hope it dosen`t take me `til your Autumn and our Spring to get the Jupiter shots underway! Once I have my focusing problems under control I should be well on the way. It took me an hour of "commuting" back and forth between telescope and screen the other night to get the moon in focus! Yours, Mark.

Hi Mark,

This map of the lunar 100 oriented to the naked eye view (with the moon at the meridian) should help straighten you out:

Plato is 83, Archimedes is 27 and the Alpine Valley is 19.

I hope you will share some pictures of Jupiter this spring from down under.

best,

Alan

Alan, actually I think the upward orientation in the shot is towards the moon`s western (or tilted a bit south-west) side, not the east as I wrote. Would this be right? At any rate it threw my own calculations about lunar features off significantly. I didn`t realise! at the time, I was in the same region as your excellent "Plato" work. Yours, Mark
