You try to observe and your eyes water so much you instantly freeze to the eyepiece, too cold.




Yep...my eyelashes have frozen to the glass on more than one occasion

I like the ranges being posted. Count me among the guys from the north.

I love the crisp clean feeling of a cold dark night. If it is so cold your equipment (and/or hands) have trouble working, it is probably too cold to be out observing--for too long anyway. But as long as cables aren't breaking and the mount still works, I would much rather deal with 0* weather than mosquitos.

I did do a small observing session (20 minutes @ -3C and high relative humidity) and used my 80mm refractor. Jupiter and the just past first quarter Moon were close together, having past by each other on a different hemisphere than mine.

Too cold for observing?

One word: Snotcicles

Does anyone else share my preference for mosquitoes rather than temps below freezing?

We have ways to deal with 'skeeters now. I can go the whole night with nary a bite. But there's no way to keep MY hands warm and still be able to manipulate the astro equipment. Not happenin'.

I know what you mean. I've never had a pair of gloves that actually keep your hands warm enough and give you enough tactile sensation and grip to do the work required in amateur astronomy.

Usually I just do without gloves. If I wear gloves at the telescope, I end up tearing them off in disgust within five minutes anyway.

i often observe at temperatures below -20 and solve the problem by wearing a pair of thin gloves used for cross country skiing under my real pair of gloves and take off these and keep the thin gloves when manipulating stuff

Francois,

I've tried double-gloving like that, also. But then the thin gloves snag too easily on the equipment and my hands become ice cold even faster. Nothing really works.

I think the problem is my hands, not the gloves or anything else. They get cold fast and stay cold. They hurt worse than any toothache. I broke my arm once. I swear my hands hurt more than that when they get cold. Not too fun. I'm pretty sure this is Raynaud's syndrome. I described it to my doctor last fall, and he even said that's what it is! But unfortunately, I didn't press it and he didn't offer any treatment. Next check up, I think I'll ask about treatment options.

Special gloves and gizmos just don't cut it.

Mosquitoes? Pfft! Big deal! Suck it up.


Mike

It is too cold when the car thermometer reads this temp for Tuesday this week.

Its too cold when your breath freezes on your eyebrows forming icicles and they are very hard to view through

Last time I was out trying to observe it was so cold the star light froze before it could enter the telescope!

You a drop an eyepiece in the Snow, then say a bad word!
Then you have to bring the bad word inside and thaw it out to hear it!!!
