After my last great prediction for clear skies and planning an imaging session earlier in the week… and then having it totally cloud over hours earlier than predicted… I decided to wait and see about last night.<\/p>\n

After Survivor, I went out and had the north half of the sky clear and the south half full of high cloud interspersed with sucker holes.<\/p>\n

Hmm.. it’s been some time.. lets try anyways.<\/p>\n

Opened up the Imaging platform to discover water inside. Arrg!<\/p>\n

The cover had come off the scope and was crumpled on the floor and wet, the scope was damp but not wet and covered with a fine layer of white particles.. unsure what yet.. will have to check in the daytime.<\/p>\n

I had noticed the serial cable end of the telescope computer interface was showing signs of rust, so I put the end connector of the new usb-serial adapter into a ziplock bag, zipped it up most of the way and put it on a shelf with the cable going up but not touching the roof or walls.<\/p>\n

The bag was full of water \ud83d\ude41<\/p>\n

I had just added last week a shelf to cover the laptop, JUST IN CASE, and the laptop stayed dry.

\nIn any event.. it was already late, the place was open so I went ahead and did three runs of Saturn (30 sec, 30 sec autoaligned and 10sec autoaligned), and Mars (same).<\/p>\n

Saturn was so low and covered with enough cloud that the exposures were relatively very long.. 89 and 98 msec.. meaning only 10-11 framespersecond.

Mars was higher, almost due south, but still enough bad cloud, transparency poor and seeing poor, with 9ms exposures, more than normal.<\/p>\n

The Moon had also come up and was in the eastern clouds, lighting up the sky.<\/p>\n

These are the best results in UT time.
