instant dew control for difficult places

Now I have a Newtonian to play with I have been concerned with dew control particularly for the secondary and even the interior face of the coma corrector.

I have used my existing refractor dew bands to put around the tube to protect the primary and thought these foot warmers were a great solution to protect the secondary and focus tube/coma corrector

The advantage of these is that because they are foot warmers they have a sticky side so you can adhere them to the back of the secondary as fixing normal hand warmers in position can be a bit problematic. They are supposed to last 8 hours so will protect even through a long imaging session.

As I have a box full I'm happy to give anyone a pair that wants to try it out before buying, just pm me :thumbsup:
