About the Kendrick Standard Dew Caps
Note: Kendrick sells dew caps (shields) in a variety of lengths to fit around the outside diameter of a telescope. Please measure around the outer edge of your OTA and then choose the correct outside diameter for your scope. Please ask one of our sales staff if you are unsure of the proper size. Thanks.
Kendrick Standard Dew Caps, AKA Dew Shields, are constructed of black ABS plastic and are all felt lined for maximum of moisture and baffling of stray light. The cap is attached by wrapping it around your telescope just below the front lens or corrector plate ring. The two outside ends are then pressed together using the sewn on velcro. A rubber strip is supplied that must be attached along the bottom of the dewcap where there is no felt. This provides a friction fit so that the dewcap stays in place once attached. It also allows enough room to attach a dew heaters around the corrector plate ring on the inside of the dewcap.
Ironically, the Kendrick Standard Dew Shield will not prevent dew from forming on your telescope. They only delay it, typically by 20 to 40 minutes after dew point has been reached. A dewcap will provide greater contrast while observing by cutting down on the amount of stray light that enters the front of your telescope due to street lights, skygolw, etc. We highly recommend the use of a dewcap if you have a SCT for this reason alone.
Q. Can I use a Standard Dewcap with a Kendrick Heater?
A. Yes you can. The Kendrick Standard Dew Caps come with a .5" thick rubber strip along the bottom. This provides plenty of room to wrap a heater around your telescope and then wrap the Standard Dewcap around the heater, enclosing the heater inside the dewcap. This changes the Standard Dewcap to a heated dewcap with the addition of a dew heater controller (sold separately).
Q. Can I modify the dewcap to accomodate dovetails and other hardware?
A. Yes you can. All you need is a utility knife. If you do modify the Kendrick Standard Dew Cap, you must make sure that the corners of the cut are rounded otherwise the corner could split on you.
