A. About Dew-Not Dew Heaters

Proudly made in the USA by AFAB, the Dew-Not Dew Remover is a thick film dew 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.

Dew-Not dew heater strips are probably the most power-efficient product of their kind on the market today. This is important if you use batteries to power your telescope and accessories in the field. Some competing dew heater designs use a larger amount of rubber and fabric during manufacture requiring additional power to heat up these elements before any heat is transferred to your telescope. Dew-Not's efficient design is about twice as power-efficient as its nearest competitor, so your battery will last much longer.

Dew-Not strips are manufactured to very high quality standards. Each heater has a velcro strip on one side for attachment. Each heater comes with a standard six foot cord. This cord length is longer than competing designs and provides you with a lot more flexibility in placement. The standard RCA phono-plug male connector used is compatible with Kendrick, Dew-Buster, and most other commercially available dew system controllers.

Protected by over 30 USA and international patents (relating to resistance heaters, methods of their manufacture, and innovative flexible, electrical circuitry), and carrying more than 20 years of constant improvements and enhancements, the Dew-Not Dew Remover is the ultimate in reliability and efficiency.  AFAB has been involved in the design and manufacture of resistive heating elements for over 25 years. Dew-Not's prices are also about half that of another leading competing brand. With Dew-Not, you get an excellent productand save power and money.


B. Selecting a Dew-Not Dew Heater

Dew-Not is available for all popular sized eyepieces and telescopes. To select the right dew heater for your scope, measure the circumference of your telescope tube (or measure the tube diameter - not telescope aperture - and multiply by 3.14) and pick one of the models based on length from the table below. For in-between sizes, choose the next larger size of dew heater.

Special models are also available for use with telescope controllers (DN16) and binoviewers (DN17). The Binoview binoviewer model is comprised of two eyepiece-sized 6" strips in tandem coupled with a 4" long Y-wire to a single RCA plug. The Binoview is the ultimate binoviewer optic dew remover.


C. Recommended Accessories

Optional cigarette lighter adapters can be purchased from other sources that will allow you to power the dew heater from a 12 volt power source. For controlling several Dew-Not strips from a single source, or to vary the power output, you can consider the optional Dew-Not Dual Channel Controller (Model DNC02).

4. INTERNATIONAL ORDERING / SHIPPING

Shipping Cost: Click on the "Shipping and Payments" tab above and select your country to see your shipping choices and cost. If you need a shipping cost estimate for multiple items, please contact us.

Delivery Time:

1) USPS First Class International: Delivery takes about 3-4 weeks after we ship your package. This can frequently take 4-6 weeks or more for several countries (8 weeks for Italy, Argentina, and South Africa; 8-12 weeks for Brazil). THERE IS NO TRACKING FOR FIRST CLASS SHIPMENTS. The information shown in your eBay account is just a customs form number - it is NOT a tracking number as incorrectly indicated by eBay. Once your package ships, we can do nothing but wait until your package arrives. Please do not become impatient and contact us in 2-3 weeks if your package has not arrived. If you don't receive the package in 6 weeks, contact us and we will work with you to resolve the issue. If you don't want to take the risk of this delay, then DO NOT USE First Class mail - use Priority or Express shipping instead.

(2) USPS Priority Mail International: Delivery takes 1 - 2 weeks after we ship your package. This can sometimes take 3-4 weeks to several countries. The USPS provides some basic tracking information for Priority shipping.

(3) USPS Express Mail International: Delivery usually takes 5-10 business days after we ship your package. You will receive a tracking number with which you can track your shipment from USPS.com. Note: If you use this option, you must send us your phone number when you check-out or else your shipment will be delayed. This is required for international postal forms.

Again, these delivery times are NOT guaranteed by the US Postal Service. The most common reason for delays is slow customs inspection and clearance in your country, and can be very long, even for Express mail packages. Upon shipping your order, delivery delays are beyond our control, so do not leave us negative feedback or file a Paypal claim if your package is delayed. Delays are quite common but losses are very rare, so your patience/cooperation will be greatly appreciated.

Customs and Duties: You are responsible for any duties and taxes that may be levied in your country. These are not included in the item price or shipping cost. We have no control over these charges and cannot predict what they may be or if they will be levied upon delivery. Customs policies vary widely from country to country (Some countries such as UK are strict about imposing hefty customs duties). It is your responsibility to check with your country's customs office to determine what these additional costs will be prior to bidding or buying. Customs fees are normally charged by the delivery company or your country's postal service, or collected when you pick the item up. These fees are NOT additional shipping charges.

A minimum restocking fee of 10% will be deducted if there is any evidence of use or wear, dirt, scratches, missing packaging/parts, etc. We may levy a larger restocking fee if the condition warrants it, or even refuse returns entirely if returned in heavily used/abused condition. Shipping fees are non-refundable (for items with free or discounted fixed shipping, the actual outbound S&H cost we incurred will be deducted) and you are responsible for all return shipping costs. Please contact us first before returning an item.

International Orders: No returns/exchanges accepted unless the item we shipped is defective. Please research the product and ask us any questions BEFORE you purchase to make sure you are buying the correct item for your needs.
