Bigger Cat = more dew
Posted 10 January 2013 - 09:41 AM
All have "regulation" length dewshields.
The 4" NEVER dews up, the 6SE occasionally and the 8SE almost always.
(Which is one reason the 8SE never goes to a dark site- I can't use my wife's hairdryer on it!)
Is this usual?
What is other people's experience of this?

Notwithstanding the above, for those jaunts away from AC current sources, best to invest in active heaters powered by a battery.

Get a dew-heater & controller. I don't need active dew prevention on my C5, but my C11 requires it.

If used properly, a combination of dew heater with dew shield should be 100% effective at keeping things clear. I have a Keating dew heater, which regulates the temperature based on an offset from ambient. I run mine about 5 degrees above ambient and it keeps things clear even on the most humid of nights. The trick is to have the dew strap wrapped around the OTA just behind the corrector (ie. not around the edge of the corrector itself).
