Another perfect night, another failure...

Of course, it doesn't help that this is the best view I have:

Mostly cloudy snowy here in the south-east of Norway, but that sometimes means better weather in the west on the other side of the mountains. I thought this one taken the 18th and posted on a Norwegian mailing list is among the better ones:

Got my new camera today. Hopefully the sky clears up tonight, and I can get some shots of either Panstarrs or just the sky in general.

The sky was perfect a while after Panstarrs set, but 30 MPH winds and ice-age temperatures put an end to all-sky photo plans...

The trouble is operating a camera and a tripod with mittens. It doesn't mix well. I once did some aurora photography in -25C and gale (i.e. windchill in the -50's) and got the back of my hand slightly frostbitten since I had to take off the mittens occasionally. I didn't realise until after a few hours. Nothing serious, but the hand was burning for a few days. If it's very windy to expose thin skin just a couple of minutes might be enough, and you wont notice right away. I've later been using a shutter release and extra gloves, and if I get cold, I switch back to mittens and take a break. And if it's seriously cold and windy, taking mittens off and on might be pretty dangerous if you're far from people. If you lose a mitten in the wind, having something spare is important.

I think this was the time I lost an entire film. This was in the 90's, so nothing digital. It was even a fully manual camera (Nikon FM2), because I wanted to be sure that it worked in the cold. If the battery died, all I'd lose was the light meter, which wasn't much use anyway in the dark. I had been waiting for and photographing auroras all day. This was in December at 78N, so it was dark around the clock. I was pretty new to photography in the dark, so when I was done for the day and the film in the camera was spent, I wanted to get it developed right away, so I could check the exposures and see if I should adjust anything. I went into the store to deliver my film. But first I had to rewind it. I began turning the rewind lever. There was some resistance, and then catastrophy, no resistance at all... I asked the man in the shop to open the camera in a darkroom, but nothing could be saved. The film was not simply torn, but utterly shattered. The camera was full of small fragments of film. Apparently, film gets very fragile if you expose it to a rapid 50C temperature increase. As I said, I was new to photography, but still, it was kind of unexpected. I lost some aurora shots, but learned something new.

My tripod is easy enough to control with gloves on and for the camera i use a remote shutter release.

I have never gotten frostbitten, but i came damn close when photographing that aurora. At one pont i realized that i couldn't feel or move my toes anymore, so i went inside to have a break. My toes had gone all white and when the feeling returned, they hurt for hours.

This is so true.

I never get full 24/7 darkness. During the deepest winter there are still few hours of twilight.

Yey for digital cameras. smile

Anyone know panstarss' apparent magnitude now? I haven't been able to find the damn thing yet.
I don't think I'm too far North- I live in Calgary, Alberta.

Edit: Antza, if you're from Finland, I'll definitely be able to see it from Alberta. I think I may have looked too late after the sun set to see the comet.. biggrin

You should have been able to see it a long time ago, it will be getting pretty dim now. Anyway, you should be using photography or binoculars to hunt for it as it was never very bright, and spotting it with the naked eye alone is not very reliable (unless you're Antza2, apparently).

Yeah that's what I figured HarbingerDawn, I'm trying at the tail-end of the opportunity here. Oh well, I'll try once more if it clears up in the city here.

I'm still holding my breath for comet ISON. :>

I might have just gotten lucky. It was hard to find but after i knew where it was, i could see it just fine.

What is the atm pressure on the surface of a comet (the coma is a temporary atmosphere in a sense)?
