Advantages:

  • Our thermally insulating material will not crack or break
  • The black lining absorbs scattered light, improving the contrast performance of your telescope
  • The dew shield is flexible, and it rolls up for transport and storage
  • Non-electric, so it doesn't generate heat or induce thermal currents that might disrupt image quality
  • Best of All... It Works !!

The Insulated Dew Shield will delay the onset of dew
It will keep dew from forming much longer than metal or plastic dew prevention devices.

Absorbs Scattered Light
They have black felt totally covering the inside to absorb any extraneous light.

Placement of the Dew Shield
Half of the shield is placed around the optical tube, and half extends beyond the objective lens.

The trick is to keep the tube temperature above the dew point
Metal and glass radiate heat faster than air, so the temperature of the telescope tube and lens always gets below the ambient air temperature. The Insulated Dew Shield slows the radiation of the heat enough to allow hours of dew free observing.

The Dew Shield will not remove dew that has already condensed on the telescope.
The time to put the dew shield on your telescope is at the start of your observing session.

Every Dew Shield is handcrafted individually
Please allow us time to make one especially for you!
