Bit of Moon in HD (test of Camcorder)

Haven't had the scope out for ages, namely weather and motivation to setup stopped me (only to be trounced with bad weather after setup).

Anyway, I had wanted to test a few things tonight. Some of you here are quite capable in the photography side of things, but I am quite a noob to the photography stuff. I know a bit on the standard "stills" camera, but I'm learning off you guys and I'm just diving straight in and using my errors as a learning tool.

Couple of things came out of tonight, that I learned about.
Namely apart from the weather that snuck in, was that "Humidity", "Prime Focus" and "Macro setting".

I did a really rough setup tonight, as I was just purely wanting to know, if the HD camcorder could do anything at night.
Even though the Moon was a bright light source, it (The camcorder) did quite well in the dark areas.
Camcorder on a tripod and fitted with a Wide Angle Lens, Scope with no EP and Camcorder was in Macro mode. I had forgotten that the "focal point" was right in front of the camera, not down the tube as I had always thought. Stupid me...That's why it never worked before.
The Camcorder is not connected to the scope at all, as it was just a trial, but very fiddly.
Here is the video (it is in 1080P) :

Since I got a weather station now and live in Melbourne, I have been learning what is good enough weather for viewing. I started at 6 C with 85% humidity and it was just ok for the trial, but then the temp dropped a little further and the humidity went to 97%. Dew and major haze.
Where I live, anything over 70-75% humidity is disasterous, due to the lights reflecting off the water vapour, from the local burbs around me. Let alone summer bushfires to bring in the haze too
I can just make out 4.0 (4.5 max) mag stars on an average night. (unaided eye)

I have a few more vids, but have to go through them to see if anything is good enough, to prove a good result in prime focus.
But I think it worked out well, considering it was very rough setup.
