ADC Limited Trial Program

Telescope Engineering Company would like to announce a new 30-day ADC (Atmospheric Dispersion Corrector) trial for TEC customers that may be interested in purchasing an ADC, but unsure if it fits their needs.

Once a $4,000 security deposit has been received, TEC will ship an ADC to your home at no additional cost with a set of adapters to test for 30 days. TEC will then hold the security deposit during this time. At the end of the 30 days, simply return the ADC and adapters to TEC and let us know if you’d like to place a formal order. If you decide to place an order, TEC will keep the deposit and deduct it from the total amount due. ADC orders are usually fulfilled 4-7 weeks from placing an order. If you decide that the ADC is not for you, however, TEC will return your security deposit once the ADC has been received and checked for damage.

Please understand that this is a personal unit and will not be available to rent for longer periods, nor for immediate sale. Return shipping will be the applicant’s responsibility.

The ADC will be inspected upon receipt from the previous trial applicant. If any damage is detected on the unit or the adapters, TEC reserves the right to deduct the cost for repairs from the security deposit or to keep the deposit in the event that a replacement is needed.

To apply, please select the ADC 30-Day Trial through our order form under “Accessories” and fill out the contact and shipping details. We will contact you within 72 hours of receiving your application.

In the event that multiple people request to take advantage of this offer, a waitlist may be started.
