YEP
Brent and Marc are spot on - EP dew control
don't ask me how or why i thought of it, but i was working on ideas for a heated box and the darn thing sprang to mind
the mug is supposed to have a temperature range of about 10 to 80 degrees C
of course you don't want it that high (80 degrees)
i only managed to get it to maintain about 20 degrees C (i have lost the setting instructions for it)
maybe not to use as your main means of heating your eyepieces - but a good backstop if you have one.
i reckon with a little ingenuity you could get a 1.25" and a 2" eyepiece in there together
one thing i noticed though - it needs to be run from a straight 12v source
it conks out on a modulated source
