Dew on Refractors and Telrad in Victoria
All,
This is a question specific to owners of 4-5" Refractors and owers of Telrads in Victoria/ Melbourne.
Over the past years, have you seen a requirement for a dew heaters for the Telrad and for your 4-5" refractro optics?
I am considering to equip myself with dew heaters for Telrad and 4" Apo ahead of the autumn and winter season.
Thanks for feedback.
