The A70Lf 2.8" / 70mm Refractor Telescope Kit with Porta II Mount from Vixen Optics is an excellent choice for a first telescope; a light, well-made optical tube combined with a great beginner's mount specially configured to work well for both terrestrial and celestial applications. The A70Lf offers the same quality glass and workmanship that Vixen optics incorporates into their larger instruments. As an achromatic refractor optical design, it is capable of rendering high resolution planetary, lunar, and deep-sky visual images.

The Vixen Porta II mount is built to support a 20 lb payload, and equipped with two fine adjustment handles for whole circle slow-motion in both directions. It is provisioned with a sturdy set of legs that adjust from 35-51". Slow motion flexible handles minimize vibrations to keep the view sharp. The A70Lf with Porta II Mount arrives with a 6x24 finderscope, a pair of 1.25" eyepieces, a diagonal, tube rings, and a dovetail plate that mounts directly into the mount. This is not a beginner's scope to use once or twice and then store in the garage. This is a serious optic for the curious budding astronomer and the already hooked doorstep sky watcher.

Includes two Plössl eyepieces; 20mm & 6.3mm
Lightweight optical design great for backyard astronomy
Included finderscope of 6x24mm with a field of View of 5°
Erecting 31.7mm image diagonal connects eyepieces to telescope
Light gathering power of 100x. Adapter thread of 42mm / for T-Ring
Aluminum 2 section adjustable tripod extends from 35.4 to 51.1" or 90 to 130 cm
Tube rings and dovetail plate quickly attaches the A70Lf to the Vixen Porta II mount
Dew / sun shield inhibits moisture, dust and unwanted ambient light on the objective lens
Simple yet sophisticated altazimuth mount suited to stargazing and earthbound use alike
Friction control system: flexible vertical and horizontal slow motion handles with 120 tooth wheel gears and whole circle movement
Multicoated optics on at least one lens surface reduces light loss and glare due to reflection offering a brighter, higher-contrast image
Porta II Mount with locking extension legs, accessory tray, flexible handle slow motion control, adjustment tool set, and removable mount head
