About this product
Model: flexiheatdewshield-3
Part Number: AZ-805
Standard unheated dew shields prolong the onset of dew formation. Depending on your location, a simple dew shield may be all that is required. However, in moist climates a regular dew shield might not be enough.
Astrozap Flexi-Heat Dew Shields feature an integral dew heater that directs heat to your optical tube assembly, eliminating any chance of dew formation.
It also shields your telescope's optics from stray light.
How does it work?
The source of heat is a thick film heater manufactured for operation at 12 volts. Sixty-six percent of the surface area is heat emitting - this means more even heat distribution and no localized hot spots or burnouts often associated with resistance wire heaters. Best of all, it won't create heat wave disturbances.
Astrozap Flexi-Heat Dew Shields are made from durable yet light weight ABS plastic and lined with black felt to help increase contrast. A 2-inch sewn neoprene rubber “Mega Grip” material wraps snugly around the telescope optical tube assembly, keeping the dew shield in place, and eliminating any chance of dew formation!
Supplied with a six foot phono-plug cable.
Will I need a Dew Controller?
When using a Flexi-Heat Dew Shield on a telescope with an aperture around 10" or larger a simple 12V Dew Heater Supply Cable can be used to connect the tape to a suitable 12V power-supply. When connected this way the heater is essentially running on full-power. This won't harm the heater but with smaller telescope apertures it might result in the optic being warmer than necessary which can effect the view and waste energy. The solution then is to use a Dew Controller which regulates the heat (also enables you to use multiple dew heater tapes). Astrozap Dew heater tapes are compatible with most good dew controllers, including those manufactured by Lynx Astro.
Two year no fault replacement warranty.

Top quality heated dew shield 20 March 2023 | Jorge
I purchased this Dew Shield for my Sky-Watcher 127 Mak, to be connected and controlled by the new Astro Essentials 4 Port Dew Controller, sold by FLO. The Dew Shield build is top quality, the materials feel very durable and strong. The velcro is really strong and easily maintains the shield's round shape around the telescope tube. The fit is really snug, there is no noticeable movement. Really impressed! Service from FLO was fast and efficient, as always.

I bought this as this one was the closest size in this range to the one I needed for my Ioptron RC6, and although just a tiny bit off of perfect, it will do the job nicely, without spending a fortune.
Quality product that works as described. 28 April 2021 | John
Excellent service from a reliable company. Product bought to prevent due build up. Apart from extreme situations it works very well. Please remember that you will need an external power source.
