Can anyone point me to information on Dew Prevention please?

I made myself a dew shield from a cheap camping mat and some gaffer tape. It works great and I have not had any problems with the scope dewing up since I have been using it.

Cheers,

Chris

To buy a dew shield you are looking at £20

I made one similar to above with a cheap camping mat £5 and stick back velcro £2

Make the tube about 2x the length of the scopes aperture. The whole job takes about 3 minutes to make.

If that doesnt work, you will be looking at dew heaters (from astronomy shops, however you will need a power source to run them), or a small travel hairdryer (also needing a power source). If you go the hairdryer route, remember it just needs a quick blast and try to do it at an angle rather than head onto the glass.
