Stellarvue SV80ED Nighthawk Next Generation Deluxe Doublet Refractor OTA

Description

This is the deluxe version of our venerable 80ED telescope. It features a two section cnc aluminum tube that is binoviewer ready. The sharpest doublet optics combined with the most accurate dual speed Feather Touch focuser and our precision cnc clamshell make this the best 80ED telescope on the market.

This is the premium version of the venerable Stellarvue 80ED Refractor telescope. We  took out all of the stops to make this the best of the series. This model has  four unique features:

• Feather Touch 2" reverse Crayford focuser. This is the best 2" focuser  on the market. Not a modified Chinese focuser but an American made, patented  focuser made by Starlight instruments
• Rotating cnc machined collet. This allows for more precise focuser  rotation, maintaining better alignment
• Precision threaded two section main tube. This allows for wider field  viewing when using bino-viewers
• Stardust Blue finish
  

Stellarvue Objective Lens: Like all Stellarvue 80ED refractors, the hand figured ED lens provides extremely high  contrast. To further enhance this high level of contrast, extreme broadband  multicoatings are used on all four 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.

Stardust Blue tube and dew shield: The tube and dew shield are made  of aluminum machined on an computer numeric controlled milling machine. All  aluminum parts that attach to the tube and dew shield are black anodized. The dew shield retracts  reducing the length of the telescope to about 17.5" 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. To  eliminate reflections in the focuser drawtube there are nine anti-reflection  ridges to block reflected light. Reflections in  the optical path are further reduced using an edge blackened objective. All of  these methods are used to preserve the outstanding contrast this instrument  provides.

Focuser: We use the Starlight Instruments reverse Crayford focuser -  the best in the industry. We use the new version  F2025DSBCRcr dual speed reverse Crayford which features 2.5" of travel,  an ultra-smooth 10:1 ratio dual speed mechanism, compression ring with two thumb  screws and ultra-low backlash system.

Focuser Rotator: The  focuser is fully rotating. To rotate the focuser, simply loosen the knurled collet in front of the focuser.

Machined aluminum clamshell mounting ring with Vixen Dovetail:   The SVR80ED  uses our unique, American made, precision CNC (computer numeric controlled)  machined aluminum mounting ring. This clamshell ring has several 10-32 threaded  holes on the side and top accommodating finder scopes, a guide scope or other  accessories. Our clamshell is precision machined and has an "easy-one-touch"  single knurled knob for tighten and loosening the ring. This permits faster and  more convenient balancing of the telescope tube.   The underside of the mounting  ring has a Vixen style dovetail rail with safety grooves. This rail fits most  telescope mounts on the market such as the Vixen, Celestron CG5 or Meade LXD-55. If you plan to mount  this telescope on a larger mount that uses the Losmandy rail our TP6 (Losmandy sized) plate  attaches to the bottom of the Vixen rail with two  screws.

Supplied accessories: The 80ED comes with our C7 side reinforced, foam lined,  airline carry on case. This case will hold the  telescope, star diagonal, reflex finder and numerous eyepieces. In addition to the supplied  accessories, you will need a star diagonal or erecting prism, eyepiece and a  tripod or mount.

Light gathering and magnification power: The purpose of a telescope is to gather light and magnify the apparent size of the object being viewed. The 80ED gathers 131 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 dependant upon the eyepiece being used. Different eyepieces provide different magnification powers. Since our 80ED 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 186 power for a 80 mm telescope. 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.
