Sent: Sunday, December 23, 2001 14:33:28 From: firstname.lastname@example.org (martyn) This (23 December 2001) evening I had a "quick" look at the crater Plato, on the Moon. Included is a pic of the drawings I made of what I saw. Temperature was -2 degrees C, it was very windy so the seeing was very poor. Nevertheless, I inserted the SP 6.4mm in my ETX 90RA to bring the shadow forward to be able to see it's shape better. It did work in spite of the poor seeing. Focusing is then a bit difficult as many of you will appreciate, so I used a clothing/washing pin on the focuser for precise focus control. Plato was right on the terminator. It's Western rim brightly lit, rising above the pre-dawn and the lit portion of it's floor dark but contrasting strongly whith the retreating shadow. Montes Teneriffe, Pico and other hills reflecting sunlight like mirrors almost. At 17:15h(16:15h UT) the Eastern rim of Plato threw a crown-like shadow on it's floor. This gives very nice insight of the "skyline" of the Eastern rim, as seen from inside Plato. After only fifteen minutes, there was a noticable difference in the shape and size of the shadow, amazing to see! There was no hope of seeing anything else inside the crater, due to the poor seeing but the shadow was quite clear, especially with a bit of study. So much to see on the moon...... Regards, martyn
