Ideally suited for astronomy and astrophotography, the green Tele Vue TV-76 76mm f/6 APO Doublet Refractor Telescope is designed to be an easy grab-and-go option for celestial observing, or a lightweight spotting scope alternative for birdwatching and other terrestrial uses.
It employs Japanese-made optical glass set in an apochromatic doublet lens configuration, designed to Al Nagler's exacting standards, to produce flat views with accurate color fidelity and improved contrast, without fringing or halos. Complementing the lens design, are broadband fully multi-coated optics that are specifically index matched to the lens glass to maximize light transmission across the entire visual spectrum and to ensure accurate color rendition, improved contrast, and clarity. A large 2" dual-speed focuser is used to bring lunar details, planetary features, or distant objects into tack-sharp resolution.
Tele Vue offers this TV-76 stripped of accessories and without a mount or tripod for users who have their own equipment and support systems and who are looking to add a competent, yet portable, optical tube assembly to their kit, or for those who wish to build a completely custom rig.
Optical Tube Assembly
- Ideal for astronomy, astrophotography, and birdwatching/digiscoping
- 76mm aperture draws in light for observing the moon, planets, and bright deep sky objects such as stars and clusters, while remaining lightweight and portable
- Fast f/6 focal ratio makes it ideal for celestial observing and astrophotography
- 480mm focal length produces a moderate magnification potential while ensuring a short optical tube for easier handling and portability
- Nagler-designed 2-element apochromatic doublet lens configuration eliminates spherical aberrations that cause distortion at the edges of the field of view, and corrects chromatic aberration for accurate colors without fringing or halos
- Precision Japanese-made optical glass specifically chosen for its purity and high light transmission properties
- Index-matched broadband fully multi-coated to complement the optical glass and ensure maximum light transmission across the entire visual spectrum, to ensure accurate color fidelity and improved contrast and clarity
- Visual resolution: 1.5 arcsec, Dawes Limit
- Sliding metal dew shield helps to keep objective lens clear of condensation
- Screw-on objective lens cover eliminates the possibility of cap coming off during transport and storage, ensuring lens remains protected when not in use
