Heater Tapes Information
ASTRO ENGINEERING Manufactured from quality materials to shrug off the rigours of the coldest and dampest observing conditions, BC&F Anti-Dewing System heater tapes are the foundations of a versatile and flexible system that will deliver years of faithful service. The heater tapes have been designed to respond to changes in the power setting as rapidly as possible. A thin layer of synthetic heat-resistant fabric allows the heat from the wire element to be transferred quickly and efficiently to the equipment to be protected. When the power is turned down, the heat will dissipate quickly ensuring that the telescope maintains top performance. The surface not in contact with the equipment is covered in soft insulating Velcro™ velour. The heat goes were it’s needed, on to your optics not warming up the air! |

Kendrick Dew Remover System
The Kendrick Dew Remover System was developed to meet the need in the astronomical community for an effective dew removal and prevention system. This system has heaters for almost all the optical components used in amateur astronomy. The photograph shows a C8 fitted with a complete dew remover system. The controller is mounted on the fork and supplies four separate heater elements. |

 | AC368 Complete Anti-Dewing Kit for 4” scopes Ref: AE-AC368
ASTRO ENGINEERINGBased around the “Mini Controller” (AC377), this complete temperature-controllable anti-dewing system is the best way to keep dew away from your 4” (tube) diameter or less telescope optics all night long. The kit comprises the AC377 Mini Controller with six temperature-control steps and a 400mm (AC353) standard heating tape. The controller needs to be plugged in to a suitable 12 to 13.8V DC power supply available separately. The tape is a standard model and is plugged into the controller lead, and is then simply attached around the front of the optical tube with an elasticated Velcro strap. When assembled the total lead length is 2.8m (110”). The kit also includes a splitter plug to allow the use of an eyepiece anti-dew heater (see item AC350 or AC351). Note: the combined heater tape rating must not exceed 1.2amps which is the maximum continuous load of the Mini controller. The controller can be plugged into the Portable Astro Power Station (see AC338), and at a typical low to mid-range heat setting the Power Station will keep your optics dew free for over 8 hours! The kit requires a suitable 12 to13.8VDC power supply to function (not included in the price).ORDER NOW WHILE STILL IN STOCK AS THIS ITEM IS BEING DISCONTINUED BY ASTRO ENGINEERING

 | AC369 Complete Anti-Dewing Kit for 3” scopes Ref: AE-AC369
ASTRO ENGINEERINGBased around the “Mini Controller” (AC377), this complete temperature-controllable anti-dewing system is the best way to keep dew away from your 3” (tube) diameter or less telescope optics all night long. The kit comprises the AC377 Mini Controller with six temperature-control steps and a 350mm (AC352) standard heating tape. The controller needs to be plugged in to a suitable 12 to 13.8V DC power supply available separately. The tape is a standard model and is plugged into the controller lead, and is then simply attached around the front of the optical tube with an elasticated Velcro strap.

 | AC377 Mini Heater Controller Ref: AE-AC377
ASTRO ENGINEERINGIf the lens cell of your telescope is under 140mm (5.5”) the “Mini” may be all the heater controller you need. Although the Mini will only handle 1.2amp maximum continuous load, this is more than enough to power, say a primary heater tape AC353 and also the AC350 eyepiece heater. Alternatively it could also power the AC351 2” eyepiece tape as the ampere ratings are based on maximum continuous loading – if the controller is used at less than full power, which it normally is, some flexibility in amp matching can be allowed. The Mini Heater Controller runs from a 12 to13.8V power supply, has a single six step power output setting and can be split to drive two heater tapes with the addition of an AC297 splitter jack. The Mini has a 1.8m (71”) output lead and has an integral cigar lighter plug for power input. With red LED “on” indication. Includes full instructions. Requires 12 to 13.8V power supply and heater tape to function, not included in the price.ORDER NOW WHILE STILL IN STOCK AS THIS ITEM IS BEING DISCONTINUED BY ASTRO ENGINEERING
