Hi, looking to buy a 12" LX 600 ans i am wondering how it will behave in the cold temperature here in Québec. Thanks much. Jean Guy Moreau.

I don't see why it would work any differently than an LX200ACF or similar in cold weather. I have a LX600 10" and hope it works as good or better than my 8" LX200GPS did in the cold. It worked without issues.

The only 'cold weather' issue I can see for the equipment is fogging of the corrector plate in high-humidity areas. A good Dew heater should take care of that

Thank you for the replies.
I am worried about the lubrification (grease) that may get too stiff at -20C.
I suppose this has been cared about a long time ago.

Cheers,

Any recommendations for a good Dew heater or cap for the LX600?

Thanks,
Charles

Haven't had any problems in freezing cold temperatures with alot of ice buildup, here in Norway.
Sooner or later I'll be incountering use down to 0 degrees F. I'll report back if there is any problems:)

It's all the humidity of your area. When Dew point approaches ambient temp. dew forms...Astrozap is a good source, that's where I obtained mine.

BTW, I bought a heated dew shield from Astrozap. I was out last night at 23 degrees F and the front lens stayed free from frost. The Starlock, spotting scope, and tripod start getting a frost buildup, though. I finally stopped when my eyepiece frosted up. I could have switched eyepieces and kept going, but I was getting tired anyway. I'm working my way through observing the entire Messier list.

Cold weather is a lot of fun lol.You need a dew heater for the front of the sct and one for starlock and 1 for eyepieces if you are doing visual.As I do mainly imaging i just keep a dew strip on the main scope and guide scope.As for gears and grease,Ive used my trusty LX200R or acf now in temps that have went down to 20 below zero actual temp with no problems.
