As far as I know, you do need a dew controller. I run my dew strips and my secondary heater off my 12v battery. When i take my laptop in the field, i use my DIY marine battery and hook the dew controller there as well.

No easy way out!

The cheapest option I could find for you is either a single controller (Telescope House £29.99) or a double controller (Rother Valley Optics £44.93). As far as power supply is concerned, ordinary batteries will be a poor choice in really cold weather or for long periods of use and in any case, both of the above come wired with cigarette type connectors which will require a leisure battery or one of those bells and whistle battery packs.

Have a look on astroboot, and get yourself one of these

adjustable output and only £3!!! I have made myself a set of heaters using these and they work a treat.

Get a jumpstarter from ebay and your power woes are over.

What about one of these?

ASTROZAP

Please note the warning made on FLO's site about the heater running at full power - but just thought that I'd mention this as a possible option.

Cheers
