I think i may have minor frostbite...

[FarSide]

What a night it was tonight - my tube was frozen solid and so was the laptop. So cold. The only thing keeping me alive was my Barbour coat. I really don't think the frost did my secondary mirror any good - i hope you guys fared better on such a bitter evening!

-21C here 2 days ago when i was out with my scope, i had to loosen and retighten the clutches on my mount because they were stuck because of the cold.

I also almost didn't get the cover off the scope, i guess the plastic must have shrunk in the cold.

Conditions were very variable because of fog from a river 50 meters away so i didn't stay out for long and didn't do any AP, just visual of the moon and jupiter.

[FarSide]

I attempted to do some AP tonight but the secondary just froze over and the view through the camera was a blur. I had frost on my laptop screen too which didn't help. I eventually had to get an electric heater out there to warm the laptop and my hands up. And -21? You are a brave person.

Not quite -21 here in Portsmouth, but i know it was a bit chilly on my cycle to work this morning. Glad to hear somebody has managed to get out, hopefully it will be a better winter than last year.

I shall be braving it tonight. I forecast clear skies and temperatures of 0. It'll be worth it..

[ubertank]

I don't mean "i" forecast. Stupid auto keyboard.

Cold here last night too, but only down to 0• lost feeling in my toes after 1 1/4 hours so packed up then. Equipment fared better with no dew on the Mak.

Woken up to snow in the SE. We'll grind to a halt as usual and it'll be all over the news! *sigh*

-21 ?

Did you decide to put a tee-shirt on because it was a bit chilly? :grin: :grin:

Looks like another clear cold one tonight as well - memo to self, get the cold weather stuff out.

That clearly demonstrates your dedication to this hobby.

I recommend Maplins battery powered heated innersoles - does the job a treat!

I had -18 sunday, I was feeling strange all monday, but the pictures turned out good

[FarSide]

I honestly don't know how you got away with no dew on your scope last night. I had frost covering my tube, the inside of the tube and the secondary. The camera, mount and other electricals were fine, heat output i guess. The scope though just a block of ice.

I went out the other night and it was -1 when i went out. I thought that was cold but -21!! Be interesting to know if i even function at that temperature lol.

Looks like tonight could be very chilly here. Allegedly it's still above freezing, but it certainly doesn't feel like it.

Lowest I've recorded in Wales (so far) was -23 deg C in December 2010. It was cold enough to freeze the Ffrwd Fawr waterfall solid but the water flowing out the mine remained a balmy 7 deg C.

[sallystar]

I poked my head out of the back door and decided to stay inside in the warm. You are all a lot braver

than I am!

[Xplode]

I think you all wish you had -5c instead of 0-5c because you wouldn't have to fight that damn dew on your gear!

Cooling for DSLR's would be less needed too at that temperature.

Good clothes and -5c to -10c is nice winter weather

The coldest i have seen where i live is -34, i live around 100km north of Oslo so it's not really that cold, in som parts of Norway -50c isn't unusual in january. At that temperature you can take a bucket of very hot water and throw outside to instantly turn it into steam, pretty cool to watch actually!

Turn to ice, perhaps?

I've seen it done with a cup of coffee just thrown into the air. It is quite impressive to see.

No it turns into steam/evaporates first, check this out:

my instinct says you're seeing both there, liquid to vapour ===> vapour to very small liquid droplets to very small ice particles

Got out again tonight, bitterly cold but i got some Jupiter imaging time in. We spent ages setting up due to a few technical faults but i got about 50k frames in before calling it a night. Still awfully cold though.
