Dew Control
Had some dew problems on the guide scope the other night. The Lunt already has a heater but not the 80F5. So trying a simple solution first. I don't have dew problems very often but this was pointing almost to zenith.
Made a replacement dew shield from a cardboard Single Malt Whisky tube that was about the right size. Hacked a hole in the side and fitted a small 12v fan to blow across the lens front. I've got a 5 v and 12 v feed to the mount on a selectable switch give me two speed options. See if that manages to cope with the occasional dampness.
