Billy Bluelight Posted November 16, 2014 Share Posted November 16, 2014 Yep, I have the same dew issues at the moment. As per the other comments, I'm surprised it's your primary which seems to suffer though. I've had a few good sessions spoiled by dew on the secondary, but the primary is usually OK.A quick waft with the hairdryer fixes dew on secondary or guide scope lens - I guess the primary would be slower to clear cos you cant really blow the front surface. Heating the back might risk overheating.I am working on a heater - will post when/if sorted. The mark 1 version is due completion soon, but a few issues already so may wait for the Mk 2 before posting!I have to say I heat the front on mine - carefully and from a distance. All seems OK Link to comment Share on other sites More sharing options...
