Kendrick Dewcap for ETX-90

Kendrick 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 Kendrick's 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. The 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 one of the Premier heaters  we offer. 

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.
