Default Lunar eclipse images wanted...

Lunar Parallax Demonstration Project

[Purpose]
To demonstrate lunar parallax (the apparent shift in the Moon's
position when observing it from different positions on the Earth's
surface) using contributed images of the Moon against a fixed
star-field.

[Project Image Contributions]
If you want to contribute to this project, all that is required is an
image of the Moon to be taken, during the totality phase of the next
lunar eclipse on the 8/9th November 2003, that shows the Moon and at
least two stars in the same image field.

Totality is predicted for 01:06 - 01:31 UT on the 9th Nov. In order
to make sure that all photos are taken at the same time, using an
accurately set watch, please try and capture a Moon/star-field image
at 01:10, 01:15, 01:20, 01:25, 01:30.

Ideally, the 01:20 image is the one that is wanted (the others are
safety net images ;-) ). If you cannot get a photo of the Moon and
stars in the same exposure, image one exposure for the Moon and
immediately take another, exposed for the stars (i.e. over exposing
the Moon).

The Moon's diameter should be as large as possible in the image frame
with at least two identifiable stars in the field. However, any image
that shows two stars and a distinct lunar disk will be ok.

If you get a result and want it to be used in the project, please let
me know by email (don't send any images yet) to pete dot lawrence at
pbl33 dot co dot uk, putting the word "parallax" in the subject header
of your email. Please don't send me photos unless I come back and ask
for them!

Your email should also indicate the time you took the image and your
location (lat/long if possible).

If anyone's interested, here's a link to a previous international
imaging project that I co-ordinated.

Thanks in advance to all contributors.
