Hi
Been waiting weeks for a clear night to finally do some long exposure imaging (having finally sorted out balance issues). Dew has not been a problem lately... so I set up the scope and leave it running and running... only to find out that after the first 30 minutes - it was all dewed over!
And to make it worse - once I put the dew heater on: the cloud rolls back!
*big sigh* I will get it all together one night...
