Abstract: The object of this programme is to draw the Moon orbit around Earth, and calculate its eccentricity, using daily photographs and a mathematical relation (as showed in the propossed "Try your skills" on the Newspapers) for estimate the Moon distance from an specific point in our planet through 28 days.

Comments by OPC

General Comments: This exercise is educationally valuable, but it should be carried out over a longer time span to obtain the results that the autors wish. It is not clear how the position of the Moon will be determined; probably by using background stars? In that case, a large field of view would be more helpful; possibly it could be carried out even with a telephoto lens, which would increase its educational potential, by putting it within the reach of a wider public.

Visibility:The Moon is now visible most of the night.

Special Comments: A small telescope may be more useful than a large one for this project. It is not clear why high resolution is needed. If the position of the Moon is found by use of reference stars, dynamic range on the images can be a problem.

Expected time consumption (including overhead): Nearly instantaneous, over a period of several weeks.

Proposed facility:Perhaps Crni Vrh 20 cm?
