Stellarvue Premium 70 mm APO Triplet Refractor
- Brand: STELLARVUE
This is the Stellarvue 70 mm f-6 apo triplet featuring our latest version of the Stellarvue 2.5" dual speed, rack and pinion focuser (FSV-25A).
This is the Stellarvue 70 mm f-6 apo triplet featuring our latest version of the Stellarvue 2.5" dual speed, rack and pinion focuser (FSV-25A). This instrument uses the sharpest and highest contrast 70 mm lens Stellarvue has ever offered. The focuser is set up to accept an optional dedicated .8X photographic field flattener/reducer converting the telescope into a 336 mm f-4.8 astrograph. This telescope also comes with heavy duty dual rings and an airline carry-on sized travel case. This is not a mass produced scope using inferior glass and sloppy mechanics. This is a truly premier 70 mm apochromat.
The Stellarvue SV70T-25SV features a 70 mm f-6 (420 mm focal length) fully multi-coated, 3 element objective lens with an Ohara FPL-53 center element.
Each lens focuses light precisely and in addition the extreme broadband coatings on each surface enhance it even further. Using it visually, the stars appear vivid and the background, velvet black. Since these coatings transmit more than 99% in the visual spectrum and far above and below it, reflections seen on CCD images are eliminated. The relatively fast speed and high strehl optics make the 70 apo our widest field imaging telescope and the visual performance is simply stunning.
Tube and dew shield: The SV70T 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: Many years in the making, the 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 2.5" focuser 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 SV70T comes with two heavy duty, hinged aluminum mounting rings. Each ring has three screws top and bottom. Threaded holes are 1/4-20. There is one center hole, two holes spaced 1.5" apart. Use the included rail for telescope mounts using the Vixen style rail or use an optional TP6 for mounts that use the larger Losmandy style rail.
Case: The SV70T comes with a thickly padded, C70 airline carry-on case. The case holds the telescope and many optional items including a diagonal, eyepieces and a field flattener. Outside dimensions: 17" x 13.5" X 8". Inside dimensions: 14" X 10" X 5.5".
