Tube and dew shield: The Access 80 comes with an aluminum tube and dew shield that is finished in Instrument White. Fittings are black anodized aluminum. The dew shield retracts reducing the length of the telescope when being stored. Extending the dew-shield minimizes dewing of the objective at night and serves as a glare shade during the daytime.

Internal tube treatment:  The inside of the main tube assembly is painted "ultra flat black" and is baffled to eliminate tube wall reflections.

2.5" Stellarvue visual/photographic focuser: Our new smooth and stable dual speed, 2.5” focuser provides a full 2.875" of travel. This focuser is perfect for visual use and imaging. The rear of the draw tube is threaded to accept our dedicated reducer/flattener (SFFR-80A). The Stellarvue focuser is a heavy-duty rack and pinion unit designed to carry a higher capacity. It has an ultra-smooth (10:1 Ratio) fine focus control to attain perfect focus every time. An internal brake system allows the user to adjust capacity. All of the features add up to one of the finest dual speed focusers available today.

Aluminum hinged rings: The Access 80 comes with two lightweight, hinged aluminum mounting rings. Each ring has three screws top and bottom threaded for 6 mm. There is one center hole and two holes spaced 38 mm apart. Use the included rail for telescope mounts using the Vixen style rail or use the optional TP6 for mounts that use the larger Losmandy style rail.

Vixen Style Rail and Balance: The Access 80 comes with a Vixen style rail with a center 1/4-20 hole and several holes and a slot to permit positioning rings for the best balance. With the smaller accesories included with the complete visual system they may be used further apart as shown in Fig.1  With heavier accessories position the rings closer together as shown in Fig.2. 

Case: The Access 80 comes with a small, portable airline carry-on case. The case holds the telescope and many optional items including a diagonal, eyepieces and a field flattener.  

Light gathering and magnification power: An 80 mm refractor gathers 131 times the amount of light the naked eye does. Although Dawes limit states maximum power for telescopes under good conditions is about 189 power for an 80 mm telescope, you can exceed this power on a steady night. Check the Recommended Accessories section to make the best choice for eyepieces.

Two year warranty and Stellarvue Service:  We are with you 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.
