CG-5ASGT & Cold New England Winters...
Posted 09 August 2012 - 02:43 PM
Does anyone have a CG-5 braving the New England elements over winter? I am thinking now, that I could keep the tripod outside and just bring the mount head out... but then I would have to go through polar alignment and what not... Hmmmmm

Well, come fall/winter we will see how it goes... But I will probably upgrade to a 365-cover...

Every time I would take the cover off to use the mount, I would hear stuff dropping out and hitting the ground. Couldn't see what it was but I noticed a bunch of broken seed shells on the ground the next morning. Finally the mount stopped working and required a lot of cleaning and replaced parts to get it working again. BTW, the little cracked seeds (as I thought they were) were actually cracked wild cherry pits from some cherry trees I have on the property. The field mice pick them up and take them to their shelter to sustain themselves over the winter. They actually lived in the tripod leg tubes (good thing I didn't have a telescope in there).

Have you had your mount out for prolonged periods in cold weather yet? I'm curious how it has performed. 3-4 hours at low temps will ensure that it's well cold soaked and experience at this level will tell you a lot about how the mount will perform.
Some CG-5s are ok with the colder temps (so far mine is one of those), others seem to exhibit quite a bit of binding at the colder temps (likely a lubrication issue).
One way to ensure better consistent cold weather performance is to re lube the mount (sort of a light weight tune up) using a good wide temp range lubricant like SuperLube. Along with the better lube some folks also open up the worm gear spacing a bit. This leads to more backlash but less binding at lower temperatures.
As for actual damage under the cover, I would personally take steps to reduce the humidity. Such as a small low wattage incandescent bulb (Christmas tree light for example) or the use of larger desiccant units (larger than just the bags that you might find electronics gear packaged with). The electronics themselves aren't likely to be damaged by the cold.
One of the biggest areas of concern with a CG-5 are the RJ connectors on the DEC and HC cables. These connectors were never designed for any kind of weather exposure and they are notorious for getting debris or moisture in them which causes intermittent connections. One good preventative step is to use a contact cleaner. These are usually hydrophobic to some degree so they keep moisture away from the small contacts. It may also help to cover the connectors with electrical tape to keep as much moisture out of them as possible.
My CG-5 gets occasional use in the winter time. I keep it stored in a plastic bin in an unheated garage. Aside from the well known HC issues in the cold it has worked very well.
