Unfortunately I couldn't see Mars all night, we had some decent cloud cover and a thunder shower move in. I even drove out of the city about a hour to get away from the city lights.

I set ISO800 (a mistake), but got a nice, very orange point image for Mars at 1/80th sec F/2. The Moon was hopelessly burnt-out at this exposure, but showed good detail at 1/1000th sec, f/8. So I calculate there's a 1:200 ratio in exposure for Moon:Mars. If I get the chance to try again, I'll set ISO50 (16x slower), and 16x longer exposure. On a pathetic little digicam, the difficult bit is finding Mars in the viewfinder. It was easy when it was near the Moon. I looked at Mars through a friend's approx 4-inch reflector a couple of nights ago. We could see a bit of surface detail, but couldn't quite make out the polar ice cap, because he's in the middle of a heavily sodium-vapour-lit town. I'll try & drag him & the telescope the 10 miles out into the countryside where I can see the Milky Way. However, it'll probably be cloudy here in NW England until June (Q: Which June are we talking about?) |
