Light gathering and magnification power: A 180mm refractor gathers 661 more times the amount of light than the naked eye. Although Dawes limit states maximum magnification power for telescopes under good conditions is about 420 power for a telescope of this size, this high-Strehl APO refractor can exceed this power on steady nights. Check the Recommended Accessories section to make the best choice for eyepieces.

Two year warranty and Stellarvue Service:  We are friends for life. Stellarvue telescopes and accessories are covered by a two-year warranty. But it does not stop there. Since we are a telescope maker, we can repair your telescope for a very nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue Telescope with confidence.

Optical Imaging Accessories:

Field Flattener: To image with this telescope at 1260 mm f-7, use the new Stellarvue SFFX-2 photographic field flattener. This giant 4" diameter flattener will provide an enormous flat field with an image circle of about 90 mm! This massive flattener uses 100 mm diameter lenses and screws directly to the rear of the Feather Touch focuser (you will need an adapter to mount this flattener to the Moonlight focuser). 

Reducer Flattener: To image at 945 mm f- 5.25, use the SFFR.72 photographic field flattener/reducer. It produces a full frame (43 mm) field. We are currently developing an even larger reducer/flattener for big chip cameras. 

Save $200 when you order one of the above optical imaging accessories with the telescope. Order both and save $400. Merely select the items at the top of the page when you order. We will align them with your telescope prior to shipping and charge you only $499 each when the telescope ships.
