Hi all,
With winter coming soon, that means dew! Currently i have no way to prevent dew on my setup,and my primary mirror gets quite dewy, so i did some research and apparently heating the primary is a terrible idea. What i want to do apparently is have a fan on, letting air flow onto the primary.
But...
The scope i have, the Takahashi MT-160 has a closed tube at the end. It does have a rubber black cover that seems to be removable, or at least cuttable. (see attached pic)
Would this work, and would it even help?
