But i'd made an observing plan based on my driveway, then peeked out the back only to see Orion big as life. I checked to see if i could do my 2 star alignment (there's no horizon and limited visibility - it's darker, that's why i use it. I could. So i set up in back, turned on the fan to cool the mirror, and, in the mean time, looked at Orion. None of the stuff from my plan was visible, so i asked my scope's computer for clusters in Orion. I went down the list. Then i looked at clusters in Auriga, which was straight overhead. After a couple successes, i stopped being able to find them. Then, i failed to find M38. That's absurd. So i checked my alignment, and somehow, i was off by some 5 degrees. No wonder.
I decided to bring the scope to the driveway to get back to the plan. I did my 2 star alignment. It more or less failed. I tried again, and got excellent alignment. First object is a cluster near the North Pole - NGC 188. I'm interested in it because, as something near the North Pole, i might be able to get an image of it with my camera with my non-tracking Dob. The idea is, it won't move that much. But by the time i got anywhere near it, there wasn't anything in the eyepiece. I looked up to see that a cloud was there instead. I looked around, and two of the stars of the Big Dipper were visible - nothing else. And in just seconds, even that was gone.
I got back in, and updated my log. It turns out that i'd only seen things i'd seen before, contrary to the plan. Next time: stick to the plan.
