Re: [APML] Coping with dew

["Eddie Guscott" <eddie.guscott@blueyonder.co.uk>]

Hi Chris

I just got back from Thetford Party where it was very very damp (doing ccd -
sorry no film)

On Friday night it was so damp it looked like someone had poured a glass of
water over my equipment - including my monitor, which refused to work the
following day.

I was using the BC&F dew heater & straps (same as the Kendrick ones) set
half way (number 5 I think) from about an hour before darkness. All lens
surfaces were bone dry 5 hours later with water dripping from every other
surface.

Hope this helps

Eddie Guscott
