Rukl's terminator prediction tables at pp. 218-219 puts the lunar terminator at 15.5 W deg longitude tonight 2-7-2006 at 3:00 UTC (2-6-2006 at 9:00 PM local time). It should be running through, and make for a nice shot of, Clavius. - Canopus56 (Kurt) P.S. To Joe. I was the one who mentioned the wide-angle view of the Moon and Mars. Photographing the Moon and the planets always presents a contrast-range challenge - the Moon being so bright. Some guys take two exposures, one for the Moon and one for the planet, and then digitally insert the Moon into the planet base-photo. I haven't done this, but since your're a photo pro, I assume you have all those fancy square filters for balancing the sky and ground exposures (the ones with only the top quarter of the filter glass with opaquing filter material). I've wondered if that also might not be a way to balance the contrast between the bright Moon and a planet. __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Sorry, Kurt -- for some reason, I thought it was Chuck. I'll post my moon/Mars shot tomorrow, not that it's so great. I got a nice moon view too through a 400 mm. lens. I wasn't using a tripod. I will try tonight with a tripod and see what I get -- using a tripod I might be able to shoot a slightly longer exposure, with a lower ISO rating so that the image is not as coarse. It depends on how much the moon moves with a longer exposure, as I won't bother tracking. As far as filters go, I don't know of a way to adjust for this kind of brightness difference. My theory is that whatever you do to one part of the photo you should do with the rest. -- Joe

Rotate or stick the filter part way in so it only reduces the apparent magitude of the Moon down to a similar magnitude as the planet. This only makes sense when trying to do the Moon and a planet at the same time, wide angle. Although the Moon has pulled away from Mars, it will be 4 deg south of the Moon on 2/10. - Canopus56(Kurt) __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

What a difference a day makes -- you can see it on the moon, anyhow. This morning I uploaded three photos into my gallery (thanks to the kindness of Cyn). The first shows the moon-Mars combo that happened Sunday night, as Kurt told us it would! The other two are the moon on Sunday and Monday nights, so you can see how much the sunrise progressed across the lunar surface in the interval. All three were taken with my Nikon D-70 and a zoom telephoto. For the moon pics, I had the zoom all the way out, which was nearly 400 mm. I lay on my driveway with an elbow on the ground and the camera pushing into my face, hoping to keep the exposure as steady as possible. I tried to use a tripod last night but the moon was so high that it just wasn't practical. Thanks, Joe
