9/06/2011. Tropical storm Lee inspired me to bring the deep-sky hardware inside. We got just under three inches of rain over a couple of days rather than the 7-10 inches we might have received, so I suspect the TeleGizmos cover would not have been challenged. When the sky began to clear today, I hustled the solar outfit into the sideyard and tried to shoot through holes in the clouds. I didn't expect particularly good seeing, but as the Sun is moving south rapidly and it will be increasingly tough to get a line of sight through the pines, I thought I should take advantage of whatever opportunity came along. It has been a while.

I used the first sucker hole to find the Sun, focused with the second, set the exposure with the third. I intended to adjust framing and capture 15 seconds of video with the fourth, but the fourth was just about 15 seconds too brief. I waited an hour and a half for another chance. When it came, I was surprised by how still the image was, how sharp the view. This air is being pulled up across the coastal plains; it has not been roiled by passing over the Appalachians.
