Hi Duane,


I've started using my dew heater strap and wonder what effect it could possibly have on my planetary imaging efforts. On my last outing I gave up after 4 hours of trying to image Mars it was wobbling like a jelly. My friend Mick Hyde who lives about a mile away and lives in similar surroundings managed to take some great shots with the exact same gear minus the dew heating but inconclusively about 30 minutes after I'd packed it in for the night.


Any comments anyone?

What about dew heater straps on scopes, will these cause problems? I have a dew buster with 

a temp sensor, which is supposed to keep things just warm enough to keep dew off (if used 

correctly), but I'm not sure. This is pretty hi-res imagery, should i be taking greater 

precautions against local heat turbulence?
