"When I consider your
heavens, the work of your fingers, the moon and the stars
which You have set in place, what is Man that You are
mindful of him?" -- Psalm 8:3,4
Moon is our nearest space
neighbour. It is the only space body, which surface
details are visible by naked eye. That's why it is very
thankful object of amateur astrophotography. All the next
photographs were done with small 3" Bushnell
Newtonian and Philips Vesta Pro webcam.

Some parts of picture are overexposed to show
darker regions near the terminator.

Lunation
How many percent of
Lunar disk can we see from the Earth during its
period?
50%?
No-no. Nearly 60%.
Why?
The orbit of Moon is tilt about 5° towards to
ecliptic. So once the Moon is above the ecliptic,
else it is below. That's why we look at the Moon
from above or from bottom - and we can see more
area at north and south region of Moon. The
second reason is that the Moon is orbiting the
Earth by the eliptical path and so it can reveal
more from its east and western side.
In the
animation on the left, you can see part of Lunar
period from 30.3.2001 to 4.4.2001. Moon is going
toward to north part of its orbit, so it reveals
its south region.
Finding a proper
exposure level is not a simple process.
Moon face is very contrasting - it contains parts
with more brightness levels than a simple webcam
allows to record. Furthermore computer graphics
cards (24-bits) allow to display only 256
brightness levels, too. The picture shows 3
photos of the moon detail - normal exposure, over-exposed
and the combination them.
The problem of exposure is described here.
During observation strange effects appear sometimes. You
can see my 1st April UFO photography ;-)
This is not a mounting, it is real transit of bat in
front of Moon disk during my observation on April 1st,
2001.
Similar transit of bat was repeated on April 2nd, 2001.
This is really proof of the life on the Moon ;-)
Short videoclip shows the view of the moon through my 3"
Bushnell Newtonian on alt-azimutal mount. The movement of
the Moon
is caused by Earth's rotation.
