  • Thousand Oaks 1"x 15" Heater Band (.94amp) for 2.5" to 4" Telescopes, used with 4-Channel DDHC Digital Heater Control Unit

    Dew heater bands are used to prevent condensation on optical surfaces in cooler weather. The most common source of moisture is dew, however; moisture from your own eye can also condense on an eyepiece in extremely cold weather. When is comes to dew, the best defense is a good offense. Simply maintaining the temperature of your optical surfaces above the dew point will prevent condensation from happening. The most problematic optical surfaces, listed in order of their susceptibility are as follows:1) Corrector Plates on Schmidt-Cassegrain Telescopes, 2) Meniscus lenses on Maksutov Cassegrain Telescopes, 3) Objective lenses on Refractors, 4) Eyepiece eye lenses in very cold weather. Thousand Oaks heater bands are wrapped around the outside of the area to be heated, such as around the metal c... [Read More]

  • Solomark Collimation Eyepiece for Newtonian Telescopes and Refractors - Cheshire 1.25"

    The SOLOMARK Cheshire eyepiece has a broad rim on which it rests when it is inserted into the telescope's focuser. This provides an exact alignment of the Cheshire so that the collimation result will be accurate even if there is play between the Cheshire and the focuser. Newtonian telescopes: Insert the Cheshire like a normal eyepiece into the telescope focuser. Turn the porthole on the side towards a light source and look into the pinhole of the eyepiece. Once the crosshair and the reflection of the secondary mirror are concentric the telescope is properly collimated. Refractors: When looking through the Cheshire you will see as many reflected discs as there are glass-to-air surfaces. (Example: An air-spaced doublet refractor will show four reflected discs, of which usually two are bright... [Read More]
