I was looking at the sky yesterday too (Tuesday) and it was all looking good. As the sun went down, the clouds came in. I don't bother at the moment even thinking about getting the scope out until the sun is about gone.
Maybe I will start doing my observing during the day? Anyone got any good "sky" filters? Something that will block all the blue light, and only let in the rest?
A couple of weeks ago I set up to take a shot of the moon around midday. By the time I got everything set up, the clouds had come from nowhere and blocked it all out....arghhh!
