Celestron Travel Scope™ 80 Portable Telescope w/ Smartphone Adapter

80mm f/5 Refractor Optics: 131x More Light Than the Eye

The heart of the Travel Scope 80 is its large 80mm primary lens, which provides significant light-gathering power for bright, clear views. This aperture produces a limiting stellar magnitude of 12 and a Dawes resolution of 1.45 arc seconds, allowing you to resolve fine details on planets and split close double stars. The 400mm focal length results in a fast f/5 focal ratio, delivering a wide field of view that is perfect for framing large star clusters like the Pleiades (M45) or scanning the star-rich fields of the Milky Way.

4.2 lb Grab-and-Go System with Backpack

Designed for portability, the entire Travel Scope 80 kit weighs only 4.2 lbs. The optical tube, pre-assembled tripod, and all accessories fit neatly into the included custom backpack, making it an ideal companion for camping trips, hiking, or simply storing in a closet for a quick backyard session. The manual alt-azimuth mount is intuitive for any user; a simple pan handle lets you move the scope up, down, left, and right to track objects smoothly. The full-height tripod is adjustable from 22" to 52", ensuring a comfortable viewing position whether you're standing or seated at a picnic table.

Start Imaging the Moon with the Included Smartphone Adapter

This kit includes everything you need to start observing and even capture your views. The included smartphone adapter allows you to connect any smartphone to the 1.25" eyepieces, turning your telescope into a powerful telephoto lens for imaging the Moon and planets. The kit comes with two eyepieces, a 20mm for wide-field views (20x) and a 10mm for higher power (40x). A key feature is the 45° erect image diagonal, which provides a correctly oriented, right-side-up view, making the Travel Scope 80 an excellent spotting scope for daytime terrestrial observation of wildlife or landscapes.

Celestron Travel Scope 80 vs. 70mm Refractors: The Aperture Advantage

While many beginner telescopes feature a 70mm aperture, the Travel Scope 80 offers a significant step up in optical capability. The key difference is light-gathering ability and resolution, both of which are dictated by the size of the primary lens.

• Brighter Images: The 80mm lens gathers 131x the light of the human eye, which is approximately 30% more light than a 70mm telescope. This translates directly to brighter, more detailed views of faint objects like the Orion Nebula (M42).
• Higher Resolution: With a Dawes limit of 1.45 arc seconds compared to the roughly 1.66 arc seconds of a 70mm scope, the Travel Scope 80 can resolve finer details. This allows for more distinct views of Jupiter's cloud bands and the Cassini Division in Saturn's rings when seeing conditions permit.
