Our STANDARD
dewcaps are constructed of black ABS plastic and are all felt lined for
maximum absorption 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.
