Yes, its a telephoto lens, not a telescope, I´ll
try to dome some shooting tomorrow if the weather allows me (tropical weather
is a curse). Mostly its cloudy all day since its winter here, there was only
one night 5/12 when it was clear (by the way new moon!) and I made some
shooting, hope to get the pictures soon.

Hey:
I´ve just bought a 70-300mm lens and I would
like to do some lunar photography with it (as a start) and I would like to
get some advices (exposure times, anything else) to get better
results. Thanks.
Roberto
Hi Roberto,
I take it then you are shooting the moon with
a telephoto lens and not through a telescope. The moon is basically
a sunlit object. Treat it as you would a terrestrial object
illuminated by the sun. The exposure for such is typically the
inverse of the film speed at f/16. i.e., ASA 400 would be 400th sec
at f/16. However, the moon at less than full phase has many shadows
in craters, etc. along the terminator, making it slightly dimmer than an
object using the "sunny 16" rule. So you may want to
bracket one or two f/stops wider with you initial exposures until you get
the feel for how the moon will react to your photo system.
