I just checked the Jupiter weather. Temp at the top of the cloud belts is minus 145 celsius. Count your blessings in Iowa! It's a virtual heat wave!!

Yup - I was out last night working on a new (to me) scope. Only 50 degrees colder outside than inside. Hmmmmm could those be tube currents? Too cold for me. I lasted only about an hour and half. Couldn't figure out the nebulosity I saw everywhere until I realized my breath was frosting the eyepiece. I'm ready for summer.

I just came in from observing Jupiter with Europa's shadow crossing the planet, just below the great red spot. Pretty nice view! I also looked at the Trapezium and could see the E and F stars with my excellent optically Meade 8" LX200R scope. Was using 9mm and 7mm Naglers, giving 222x and 285x. It was 16 degrees out, but no wind, with some high thin cirrus clouds. I set the scope out around 4 PM to cool down.

I have been out a few times when the temperature was under 10 degrees, but when doing this, have to have an object that is somewhat unusual to view, like the shadow transit on Jupiter like tonight or as in the past, a comet.

Jupiter was exceptional here. I had my C14 out all weekend here in calif. I agree its way too cold, but I run two propane heaters on me, away from my scope and it gets the job done, 42000 BTU's each. Id never manage to observe with out them this time of the year.

I'm ok to about -15C then the discomfort start to overshadow the enjoyment. Also humidity matters as much as temperature, much harder to stay warm in a cold and humid climate than cold and dry. Not to mention the fact that dry air is good for the seeing so you have more reason to be out in the first place. Lucky me living in a northern coastal city where cold and humid is a way of life.
On the other hand, I was out observing in -10C just the other night and I had a great time with M43 and Jupiter so temperature is nothing to obsess about

Any mosquitoes around your parts?

It actually gets somewhat cold in the San Diego mountains. Last night right now accuweather says it 22F with a 10mph wind at our place out there. It's generally windier and warmer.

I'll observe at 20F but I know some of you are out there when its below zero. I wear heavy shoes/boots with thermal socks, sweat pants, jeans topped off with snowboarding pants to keep out the wind. Up top I wear thermal under shirt, a sweater, a heavy flannel shirt and a down jacket. If it's really windy, I have a LL Bean Coat/Jacket that goes on top. On top I wear a fur hat and wear gloves though I am always taking them off.. I stay out a couple of hours before I have to go inside to warm up.

What keeps me going: Thinking of you that are there when it's really cold.

I'm using a Cabela's Ice Fishing jacket, and pants if necessary, fur-lined cap, and warm Uggs and I'm very comfortable siting at the eyepiece in 32°F temps. RH become more important as you don't want dew freezing to frost over everything. Cabela's makes great freezing weather observing clothes! Out here in coastal California two nights ago, I was enjoying Jupiter and various DSO's and didn't realize the temp. was down to 35°F by 9pm. It dropped down to 28°F a few hours later on. Unusual -- winter time at night is usually in the low 50's.

I use the "citrus test". If it's cold enough that I need to cover my citrus trees with plastic, it's too cold for anything but a brief session. Moving around, I can be comfy in shorts and fleece jackets down to about 30F. Sitting still, though, is a different beast. I bundle up for long sessions and my cut-off is about 34F for an all-nighter.

Hmmph. I actually prefer -7C (20F) to mosquitoes and dew.

Down pants and down jacket. A handwarmer helps too, then I can manage with leather gloves to maintain dexterity. One to four hour sessions are regular with good clothes, depending on humidity and wind.

-20C (-4F) is my limit, and even then I will go out only if I have a new toy to test or some celestial event is happening, and there is no better weather in the forecast.

Keith,
My limit is also -20C, if there is no wind. I have to drive to my dark observing site, so demounting my scope & mount can be a tough game after a half night sitting still at the eyepiece. But who can resist a rare clear sky? Warm clothes (scooter-overall)are just as imortant as good and well collimated optics when one has to observe in minus C degree climate 4-5 months/year. Of course a choclate bar and something warm to drink is also essential.

I grew up in Wisconsin where we had to plug in our cars at night, but having lived in the desert for about 28 years now, I don't even like to go outside when it gets much below 50F anymore. I never thought that I would find seat warmers useful in my car in the desert, but I was wrong.

It's never too cold (except when using a Mak). My personal best is observing at -35F.

Last night it was -4F. Quite pleasant, really.

I'd like to winter-over at NPX looking after the South Pole Telescope.

Coldest I've set up in was around -10F. My filter wheel worked for 6 hours before it finally 'gave up'. The driver keeps track of the time to the next position and the motor slowed to the point it failed the test!

Luckily, it seems like in SD that when it's really cold out, it's not very windy... at least in my part.

Get a mallincam and do your winter observing from inside with a few active repeater cables

Instead of two sets of long johns, try thermal underwear(top and bottom) and jogging pants and top;the two layers of longjohns act as one layer but the looser jogging clothes will trap warmed air .Over those you want something that will stop the wind.Currently I make do with denim pants and a flannel shirt and one of several sweaters covered by a unlined or insulated hooded hoodie,or an industrial rated insulated coat.Knit cap too.

Thinking of getting the knitt face mask!

And sometimes it is just too much bother to get bundled up .

All those construction and outdoor workers must wear Carharts and Dickies for a reason.Keep in mind many of them are pretty active and the heavy equipment operators nearly all have heated cabs or at least cabs unlike the old exposed bulldozer seats.

For me, it's too cold to observe when you can do this.

It's too cold when the wind is blowing 20 mph, single digit temps and with a waxing gibbous moon..... like tonight. However, I do have the telescope set up out there and waiting, just in case the wind abates.... Phil

My eyelid tries to stick to the top of my favorite volcano top ortho.

Happened to me a couple of weeks ago, it was -5F. I lasted 45 minutes. I managed to frost over two eyepieces with my breath. I won't be observing in those kinds of temps again.

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 would rather have mosquitoes and dew than cold and frost. I find it's easier to deal with the mosquitoes and dew.

If it's colder than the '20's, I usually don't go out to observe. I've been at my dark site for as long as six hours in 20 degree temps. But about every hour-and-a-half I take a break in the warm car for 20 minutes or so.

All those construction and outdoor workers must wear Carharts and Dickies for a reason.

I can only speak about Carharts. They are high quality, very much wind resistant and warm. Carharts are available in Brown and Black. The black are much warmer. Don't wear the black if you're involved in any activity cause they will be too warm.

The only parts of my body that really get cold and stay cold are my hands and feet ... especially the hands. It's easy to keep the trunk, legs, arms and head warm.

BigC,

Instead of two sets of long johns, try thermal underwear(top and bottom) and jogging pants and top;the two layers of longjohns act as one layer but the looser jogging clothes will trap warmed air .Over those you want something that will stop the wind.Currently I make do with denim pants and a flannel shirt and one of several sweaters covered by a unlined or insulated hooded hoodie,or an industrial rated insulated coat.Knit cap too.

Yes, doubling up the thermal underwear and wearing sweat pants and top do the trick for me. Then I wear a double-layered coat and over that a DarkApparel vest. I put a tube warmer - I don't know what they're called - around my neck, and a thermal cap over my head and ears. If it's really cold, I'll wear a face mask.

The only parts that still get cold are my hands and feet. Two layers of socks, chemical heat packs on the toes, and high loose boots make my feet bearable, but not as warm as the rest of my body. But the hands are a lost cause. I need them exposed in order to work at the telescope.

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?

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 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
