    StellarVue Access 80mm Super ED/2.5" SV Focuser

    SV-80A-25SV StellarVue Access 80MM Super ED/2.5"SV Focuser

    An affordable example of a Super Apochromatic Refractor, the StellarVue Access 80mm is composed of a unique composite of materials intended to cut down on the cost without sacrificing any quality whatsoever- and we'd say they pulled it off! The objective was designed so as to contain an apochromatic doublet which uses a combination of FPL53 and Lanthanum which works to keep your image contrast high. Each and every lens is aligned by the manufacturer before they ship it out- ensuring that you'll be receiving color-free visual performance without any kind of price mark up as a result of it! Meanwhile, the 2.5 inch focuser is a work of craftsmanship in it's own right- it's smooth and steady dual speed performance provides a full 2.875" of travel- perfect for use in imaging or visual work. The heavy duty rack and pinion unit in question has a surprisingly smooth 8:1 ratio focus to ensure perfect focus and control every time, as well as it's superior, heavy duty design ensuring smooth and stable drawtube travel every time.
    The StellarVue Access 80mm also comes equipped with a Dewshield finished in Instrument white with black anodized aluminum fittings; this dewscope is retractable as needed, and extending it both serves the purpose of shielding your scope from overnight dewing, but also helps protect it from Sun-glare during the day.
    Meanwhile, the inside of the tube is painted black and treated so as to prevent any internal tube wall reflections, further increasing performance by doing so! To further increase the value of this item, it is packaged with two lightweight, hinged aluminum mounting rings. Each of these rings has three screws on the top and three on the bottom, and the threaded holes in them are 6mm. There's one central hole, and then a pair spaced 38mm apart.

    • Does the focuser have two thumb screws to hold a diagonal in or just one ?

      It does have two thumb screws for the 2", but only one for the 1.25" eyepiece holder.

    • First question is this still in stock? Second ... The Dove tail it comes with will it fit my Celestron VX Mount? If not what is needed for it. Third ... The case is included? Finder scope bracket yes or no? Thanks

      I just physically looked and the Used Meade 115 is in stock. It comes with a standard Vixen Dovetail, which will fit the Advanced VX mount. The case is included, but I do not believe the finder scope bracket comes with it. Sean

    • Hello. Would this work well with a AT72ED? If so, what spacers would I need to reach 55mm with canon T3i? Thank you.

      This reducer will likely work well, as your scope is an ED doublet within the parameters that this reducer works best. All you need to get to 55mm is a standard Canon T-ring (11mm), and your Canon DSLR (44mm).
