My workplace ordered one of these the other day by mistake, and for the price of $14.43+ post.

It's fully adjustable temp wise, has a couple of heat pads which are essentially the same systems as dew heater straps.

Whilst not exactly tailored for astronomy, it's interesting.

Well, at 80C, it would definitely eliminate dew!

Cheap and useful if you put some resisters in it. Bring it down to 7 - 20 c :thumbsup:

Looking at the straps, they are the same as I made mine. Nicrome wire :)
