TeleVue AP 60/360 TV60 OTA

Description

Packing down to just 254mm for airline carry-on transport and expedition astronomy, the TeleVue AP 60/360 TV60 OTA is a compact travel apochromatic refractor optical tube assembly built for mobile observers. Sized with a 60mm (2.36 in) aperture and a 360mm focal length at an f/6.0 focal ratio, this portable refractor delivers a 1.93 arcseconds resolving limit and reaches magnitude 11.4, functioning as an expedition telescope, a quick-look lunar instrument, or a high-resolution birding spotting scope.

The optical system features an air-spaced extra-low dispersion doublet objective utilizing special dispersion fluorite-equivalent optical glass, coated with proprietary TeleVue multi-coatings with an unobstructed 0% central profile. Measuring 254mm in retracted length with a 70mm outer tube diameter, the compact body supplies 125mm of back focus from the 1.25-inch drawtube. Fitted with a smooth 1.25-inch helical microfocuser mechanism, this 1.45 kg (3.20 lbs) optical tube illuminates a 35mm image circle optimized for APS-C format sensors and visual diagonal use.

Key Features of TeleVue AP 60/360 TV60 OTA

Engineered for maximum optical performance in a pocket-sized chassis, this 60mm ED refractor pairs fluorite-equivalent glass with a dual-drawtube helical focusing system. Its lightweight 1.45 kg build, integrated tripod mounting block, and soft padded carry bag make it practical for field excursions and international travel.

Fluorite-Equivalent Doublet Glass & Optical Contrast

The air-spaced doublet objective uses fluorite-equivalent optical glass to control chromatic dispersion, delivering color-pure views of lunar crater rims and terrestrial wildlife plumage. The unobstructed optical train preserves high contrast, supporting practical magnifications from 8.6x up to 120x.

Helical Microfocuser Control & Quick-Setup Mounting

Focusing is accomplished via a two-stage system featuring a sliding rapid drawtube for coarse focus and a fine helical thread mechanism for precise adjustments. The integrated mounting plate features a standard 1/4-20 thread for direct attachment to photo tripods, while a padded Cordura bag protects the 1.45 kg optical tube assembly in transit.

• Helical 1.25-inch microfocuser with sliding drawtube for fast coarse focus and fine-threaded tuning
• Integrated adjustable mounting block with 1/4-20 thread for direct photo tripod attachment
• Custom soft padded Cordura carry bag providing lightweight transit protection
