Stellarvue 70mm APO-TRI/2.5" R/P Focuser/D1029ED DIAG/CASE



This fine piece of equipment is named as the Stellarvue 70mm F-6 Apo Triplet; featuring the latest version of the Stellarvue 2.5" dual speed rack and pinion focuser, this telescope set is a fine piece of craftsmanship for those planning to survey the night sky. It was designed using the sharpest and highest contrast 70mm lens that Stellarvue has to offer, in conjunction with the aforementioned high quality focuser. This is no mass produced scope crafted with inferior glass nor sloppy mechanics- but a premier 70mm Apochromat from Stellarvue, designed and crafted to exacting standards.

The aforementioned lens is a 70mm F-6 with a full focal length of 420mm, fully multi coated. It's a three element objective lens utilizing the Ohara FPL-53 center element- and lens focuses light precisely and in addition, the extreme broadband coatings on each surface enhance performance even further. The visual result is a stunning display of vivid bright stars on a velvet black background of the night sky- contrast beautiful and dichotomous. These coatings transmit more than 99% into the visual spectrum and far above and below that- utterly eliminating reflections seen on ccd images. Combined with the relatively fast speed and high strehl optics, this all comes together to make the 70mm Apo Stellarvue's widest field imaging telescope, and leaves the visual performance absolutely stunning.

Included in this package is the D1029ED deluxe 2" diagonal, as well as a thickly padded airline travel carry-on-case for ease of transit. The diagonal further increases performance, while the carry-case goes out of it's way to ensure ease of movement when taking the scope to any site from which you might wish to observe.

The SV70T furthermore comes with an aluminum tube and dew shield finished in fine Instrument White, with Black Anodized aluminum fittings. The dew shield is designed to be able to retract when being stored- allowing you to reduce it's length notably to make it easier to fit away- meanwhile, extending that same dew shield minimizes overnight dewing of the objective, and provides a glare-shade during the daytime.

Let us continue on to mention the long labored over 2.5" Stellarvue visual and photographic focuser. Many years in the making, this latest design within that line is smooth and stable; a dual speed, 2.5" focuser providing an ultra smooth fine focus control at an 11:1 ratio, so as to ensure perfect focus is attainable everytime with a minimum of work. Ideal for both visual and imaging use due to it's design, this focuser provides a full 2.875" of travel. An internal break system further enhances the design by allowing the user to adjust capacity as needed. All together this can be summed as one of the finest dual focusers available today. And indeed- summing all these features together, we find one of the finest 70mm Apochromatics available today!
