Stellarvue 102mm f/11 "Planet Killer" Achromat Telescope
Stellarvue calls this classic refractor their “planet killer achromat.” In order to create a refractor with such a infamous title, they started with a very accurate, fully multi-coated 102mm f/11 Fraunhofer achromatic objective, and then mounted it in a Stellarvue Stardust White, fully baffled tube. This SV102 comes with dual rings, a retracting dew shield and thread on cap, and a heavy-duty Stellarvue 2.5" rotatable, dual speed focuser with 2" and 1.25" adapters.
Specs & Highlights...
Objective Lens: 102mm, 1100mm focal length, air-spaced doublet Fraunhofer achromat, broadband full multi-coatings for extremely high contrast.
Tube Assembly: A fully baffled, precision machined optical tube assembly made of aluminum.
Dew Shield: 4-7/8" diameter dew shield made of aluminum, retracts for portability.
Focuser: 2.5" Stellarvue visual/photographic focuser: Many years in the making, the Stellarvue smooth and stable dual speed, 2.5” focuser provides a full 3.2" of travel. This focuser is perfect for visual use and imaging. The rear of the draw tube is threaded to accept the dedicated SFF7-25 photographic field flattener for most cameras and the SFF3-25 for large chip cameras. The focuser comes with two compression ring eyepiece adapters that are 2” and 1.25” respectively. 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. The focuser is fully rotating with a wide groove for smooth and precise rotation. All of the features add up to one of the finest dual speed focusers available today.
Mounting Rings: Dual black anodized, hinged, aluminum mounting rings. Rings have five 6mm threaded holes top and bottom. Holes include one center hole and two holes spaced 1.5” and 60mm apart.
Dimensions: 105mm main tube diameter. Telescope is 39.25" long with dew shield retracted, 44" with dew shield extended.
Weight: 11.8 lbs with hinged rings and Vixen rail.
Finder & Case: OptionalImage shows optional equipment. This telescope comes with OTA, 2.5" focuser (2" focuser depicted), dual mounting rings, and eyepiece adapters.

Product QuestionsQuestion by: waggle on Jun 16, 2014 11:02:00 AMHello Waggle,
A 6" or larger Dobsonian should clearly show Saturn's rings and Jupiters bands and moons. The image will be relatively small, however, because you can only use so much magnification before the image becomes blurry. A good rule of thumb is for every inch of aperture, you should be able to use 30-40x magnification in ideal seeing conditions. So a properly collimated 6" Newtonian/Dobsonian should be able to achieve optimally 180x to 240x magnification. You'll need a higher power eyepiece, (6-9mm) however, to get those larger views on the best nights, otherwise a 12mm eyepiece would be just about right.Answer by: galileoson (Admin) on Jun 17, 2014 12:00:50 PM
