Additional Info
The Stellarvue SV105 was designed as an outstanding 4” class apochromatic imaging scope. While it serves as a very good vidsual scope, when combined with our dedicated field flattener, imaging performance is excellent. Numerous images posted on the Internet show how deep this lens can reach, revealing faint details and extended nebulous regions.
Fully multi-coated apochromatic triplet objective: Using a 105 mm f-7 apochromatic triplet objective, this telescope provides reflector-like color correction. To further enhance contrast, extreme broadband multicoatings are used on all six air-to-glass surfaces. This boosts contrast, making the stars appear vivid and the background velvet black. These coatings transmit light above and below the visual spectrum. This is important to minimize reflections seen on ccd images.
Instrument White aluminum tube and dew shield: The aluminum tube and dew shield is painted in our unique, textured Instrument White finish. Black anodized aluminum fittings give this telescope a very high-end, classic look. The dew shield retracts reducing the length of the telescope when being stored. When the telescope is used, this dew shield may be extended to minimize dewing of the objective at night and to serve as a glare shade during the daytime.
Internal tube treatment: The main tube interior is painted ultra flat black inside and is properly baffled to eliminate any tube wall reflections. Reflections in the optical path are further reduced using edge blackened objective elements. All of these methods are used to preserve the outstanding contrast of this exceptional apochromatic lens.
3" Stellarvue dual speed focuser: The 3" focuser has more than 112 mm of travel. This focuser is perfect for visual use and imaging. It has ultra-smooth coarse/fine focus knobs (10:1 Ratio) and an internal brake system.
Aluminum hinged rings: The SV105 comes with two 4.1" aluminum mounting rings. Each ring has five screws top and bottom. Threaded holes are 6mm. There is one center hole, two holes spaced 1.5" apart and two holes spaced 60 mm apart. Use the optional TP-10 rail for telescope mounts using the Vixen style rail or use the optional TP6 for mounts that use the larger Losmandy style rail.
What else do you need? In addition to the supplied accessories, you will need a star diagonal or erecting prism, eyepiece(s) and a mount. You may also want to purchase our C9S case (offered above at half price) and a reflex or optical finder scope
Light gathering and magnification power: The purpose of a telescope is to gather light and magnify the apparent size of the object being viewed. A 105 mm refractor gathers 225 times the amount of light of the naked eye. This will reveal faint objects in space. Magnification power (the increase in relative size of the object being viewed) is dependent upon the eyepiece being used. Different eyepieces provide different magnification powers. Since this telescope uses a highly accurate, hand figured objective lens and is triple tested in the USA, these telescopes are free of coma and astigmatism seen in many import telescopes. This provides sharper details when viewing at higher powers. Dawes limit, which is the stated maximum power for telescopes under good conditions is about 250 power for a 105 mm telescope. But don't be surprised when you exceed this power on a steady night. This is a true apo triplet capable of very high power when conditions permit. Check the Recommended Accessories section to make the best choice for eyepieces.
Two year warranty and Stellarvue Service: 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 nominal fee years after it goes out of warranty should you accidentally drop it. Buy a Stellarvue with confidence. Our customer care is legendary.
