Half a Moon

EDIT: I went back outside and got the focus better, so I've replaced two of the photos in this post 
EDIT 2: Astronomy Album. A work in progress!
My attempts at using my Pentax spotting scope (a PF-80 EDa, for the technically minded) as a giant camera lens are continuing. The good: a real Canon lens of well over 1000mm would cost more than a trip to Antarctica. Way more. The downside: stability and focussing are tough.
This scope is a fairly new addition to my kit but has already proven its worth many times over. On my last trip to Canada, I scanned an avalanche slope 4km distant - and found a grizzly bear!
No bears here in the North Downs, but the moon is rising at a convenient hour. It's also at a convenient phase. Full moons are not particularly rewarding to photograph as the lack of shadows tends to hide the details of the surface.
I really need a second tripod for this lark, but...
I was quite pleased with this. Here's a crop showing some lunar mountains (the Montes Caucasus in the north, the Montes Apenninus south) and the Mare of Serenitatis. The big crater at the top right is the Aristoteles Crater, which I believe was mentioned in the epic Herge tale Explorers on the Moon
Then I did a trick that I first saw in the Sky at Night magazine - inverted the image to show more details.
I like the effect. I've also discovered the bulb option on my camera's shutter (heh, you never know, reading the manual might be a good idea
) EDIT, 19:15pm - it's a bit too cloudy to take good star trails at the moment but I did get a seven minute exposure earlier, which nearly killed my poor, long-suffering lithium battery. I suspect its torture is likely to get worse. For a first attempt at proper star trails, I thought this okay. The bright blue star trail was left by Vega, the fifth brightest star in the sky.
