Dew
« on: February 28, 2013, 12:13:26 AM »
OK so I've taken my first faltering steps into AP by sticking my DSLR to the eyepiece holder

Given our tendency for high moisture content in our air, what do you guys do to minimise the threat of dew to the electronics of your camera and laptops in the field?

I'd like to be prepped for any attempts I make at AP at the weekend soon :)

I don't really worry about the laptop but for the secondary, EP, Barlow, filters, DFK I use a little travel 12v hair dryer which works a treat and was only 12 from Go-Outdoors. Mind you it is just a temporary solution as the dew will come back eventually and you will need a power tank of some sort as well.  :)

I have one of those but I'm not sure how close our cars will be to the obs site at Glebe house

I'm concerned more for my camera than anything else (laptops, for me, are easy to buy :) )

For Glebe house I will also be bringing an old hair dyer that I can plug into my extension which I can run from the house at it will save using my power tank if possible. Feel free to use that if you like, it's what I do when I'm setup in the garden as well.  :)

Never had a camera go funny in the Dew. I usually have the 60D on a Tripod and the 550D on the scope. There fairly well weather protected and on a Newt the Secondary goes dew'y well before the Camera.

Yeah, cameras are fairly damp-resistant. If any of mine glitch in the dew, I just off/on it and it's usually OK. Carrying a paper towel to wipe of any excess wouldn't be a bad idea though. One time we all met at Loudoun Hill last year, I did a time-lapse, and the last half of it was ruined due to dew ;), but that was just the lens - the camera itself was fine.

As said, the camera is pretty tolerent. Sometimes I will use a dew heater on the lens, much the same way you would on an SCT.
