DEW HEATER RING
SETUP GUIDE
Models # 94050, 94051, 94052, 94053, 94054, 94055
ENGLISH
The Celestron Dew Heater Ring provides the best dew prevention
solution for your Celestron Schmidt-Cassegrain (SCT), EdgeHD,
or RASA telescope. It integrates directly into the optical tube
assembly, and "lives" with the telescope so you'll never forget it
or need to uninstall and reinstall it. Additionally, since the heating
element is in direct contact with the Schmidt corrector lens, it
provides more effi cient power usage than heating strips that wrap
around the exterior of the telescope tube. For best power effi ciency
during use, there is also an integrated thermistor in the ring.
When used with one of the optional Celestron Smart DewHeater
Controllers, the thermistor provides data to the controllers to
apply just the right amount of power to keep the corrector free
from dew all night while minimizing power usage.
Please read through this entire manual before attempting to install
or use the dew heater rings.

INSTALLATION
WARNING: The dew heater ring comes in direct contact with the telescope's Schmidt corrector lens and
provides mechanical support for this optical element. When installing the dew heater ring, it
will be important not to change the position or orientation of the Schmidt corrector, or optical
performance may be affected. There are 4x set screws that support the edge of the corrector.
Do not attempt to make adjustments to these screws or optical performance may be affected.
Additionally, be very careful not to damage the Schmidt corrector itself when installing the dew
heater ring; make sure you are in a well-lit room and are focused on the task at hand before
you attempt to install the ring.
1. Orient your optical tube assembly (OTA) vertically, so that the front
of the telescope is pointing straight upward. We recommend using
your telescope mount to achieve this orientation. This may require
shortening the tripod legs for a workable height (for German EQ
mounts, see Figure 2) or removing the entire mount and OTA from
the tripod (for fork-mounted telescopes, see Figure 3). It is very
important that the OTA is pointing vertically during installation. This
will help ensure the optics do not shift or move during installation.
