Title: Clavius
Post by: Ian on May 20, 2003, 16:16:00
I took this the weekend before last, the seeing was a bit swimmy but the transparency was good. This pic is around 300 frames of a 1000 avi. 8" Europa at newtonian focus (apparently prime focus is the wrong term).

The are some interesting shadows across the floor of some of the adjoining craters clearly showing the relief of the crater rim.

It's not quite as good as Rays Clavius :smile:

Fantastic pic. I remember a few years ago I tried to see exactly how much detail I could see with the Questar by drawing all the tiny little craters on the floor of Clavius. I'll dig it out when I've got a moment.

Lovely image Ian. It was interesting to compare above with Ray's image with its slightly different illumination. Would they be about a day apart in the lunar cycle or less than that?

difficult to tell, mine is definitely a younger moon, the illumination is much closer to the horizon. It also appears to demonstrate a change in the libration too.
