Kendrick Dewcaps

Standard Dewcaps

Standard Dewcaps Our Standard Dewcaps are constructed of black ABS plastic and are all felt lined for maximum absorbtion 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 one of our heaters around the corrector plate ring on the inside of the dewcap.

Ironically, dewcaps 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. Our Standard Dewcaps 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 and you have the choice of using either our Premier heaters or the low wattage FireFly heaters.

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 our dewcap, you must make sure that the corners of the cut are rounded otherwise the corner could split on you. See an explanation on how to do this at the Dewcap modification link below.

ZAPCAP Heated Dew Caps

ZAPCAP Heated Dew Caps Our ZAPCAPS are constructed of the same black ABS plastic as our standard dewcap line, are all felt lined and are attached by wrapping it around your telescope just below the lens or corrector plate ring. The two outside ends are then pressed together using the sewn on velcro. The ZAPCAPS have a built in low wattage heater that makes good contact with your telescope to keep it free of moisture. The heater is inside a rubberized sleeve and it is this sleeve that provides a friction fit and keeps the ZapCap in place.

We have ZapCap dewcaps to fit all the most popular telescopes. If you do not see a size that will work with your size telescope or need some kind of custom work done ot it to make it fit properly, contact us. We will make a dewcap or modification for you at a fair and reasonable price.

Q. Are they good quality? Will they last?
A. We always do our best to provide the best value for money as we can. We use top quality materials, and take pride in our build quality.

Q. Are the heated dewcap power cords flexible in the cold?
A. In non summer like temperatures, the power cords will stiffen up as they get cold. If there is a demand from our customers for flexible cabling in cold conditions, we will provide it as an upgrade option.

It is not recommended that this dewcap be used without a controller.
