Frequently Asked Questions

How long will it take to get my scope?

The typical delivery time for an AG Optical Systems telescope ranges from 3 to 10 months depending on the type of astrograph you order. While AG Optical Systems attempts to deliver each telescope as soon as possible, we are dependent upon suppliers who have production schedules over which AG Optical Systems has no control.  One thing of which you can be sure is that AG Optical Systems is constantly striving to reduce delivery times and will keep you well-informed should any delays occur.

How do I place an order?

AG  Optical Systems requires a 50% deposit of the total value of the product you order.  Once we receive this deposit we will begin the process of building your scope.  When the telescope is completed and ready to ship, AG Optical Systems will contact you with the balance due on the telescope.  The telescope will be shipped when AG Optical Systems receives the balance due on the order.  Do not assume you have placed an order until you explicitly  request the item and have received an invoice from AG Optical Systems that lists the item.

Can an iDK telescope be used visually?

Yes.  Any iDK telescope can be used for visual observation using common eyepieces and eyepiece adapters.

What is the AG Optical Systems Thermal Control System?

The AG Optical Systems Thermal Control System consists of a PC application, primary mirror cooling fans, primary mirror heater, secondary mirror heater, and three temperature sensors.  Based on user defined settings, the system will automatically trigger cooling fans and/or heaters to speed the cooling of the primary mirror while preventing the formation of dew on the primary mirror and secondary mirror. 

Who makes your optics?

We use US manufacturers for our corrector elements to ensure consistent and reliable quality for these critical components.  Our mirrors are manufactured by Ostahowski Optics.  Ostahowski Optics has decades of optical manufacturing experience and is well-known for producing high quality optics for public and private sector markets.

How will my telescope be shipped?

AG Optical Telescopes that are 12.5" and smaller are shipped in heavy duty, foam-lined cardboard boxes.  The telescope is carefully wrapped in a heavy bubble wrap and securely packed in the box.  We typically use FedEx Ground service unless the customer requests another delivery service.

AG Optical Telescopes larger than 12.5" are shipped in an extremely study, professionally made wooden crate built specifically for each telescope type.  Each crate is foam-lined while the telescope itself is securely wrapped with several layers of bubble wrap.  AG Optical Systems uses well-established freight shipping companies to securely transport your telescope to whatever destination is required.

How do you test the optics in my telescope?

AG Optical Systems has a multi-step testing process to ensure that the optics you receive will perform to a high standard.  Our first step is to source our optics only from well-established, professional optical suppliers who have shown that they can deliver consistently a high-quality optic.  Interferometric testing was used on early prototypes of each telescope type to prove out the design and manufacturing process.  Production optics are testing using high-quality reference elements and various tests to include null testing of the entire optical system at focus.  AG Optical Systems has a large collimating telescope with a high quality optic that we use to check every telescope that we manufacture.  We star test each telescope and use Ronchi testing to assess the system level performance of each telescope before releasing it to the customer.

Does AG Optical Systems sell telescopes overseas?

AG Optical Systems sell telescopes overseas only through our authorized European dealer.
