Our take on the National Geographic Sky View 70 - 70mm Refractor Telescope

The Sky View 70 is an entry-level 70mm achromatic refractor on a full-size adjustable tripod. It ships with two Kellner eyepieces (25mm and 10mm) and a 3x Barlow, giving 16x, 40x, 48x and 120x combinations, plus a smartphone adapter for simple lunar and planetary photos. The 70mm aperture is enough for craters, Jupiter's cloud belts, Saturn's rings and the brightest clusters and nebulae, but not faint deep-sky objects. It suits beginners and casual family viewing; compared with larger 90mm-plus refractors and tabletop Dobsonians it gathers less light and its mount is lighter, but it is simpler to set up and includes the phone adapter many rivals leave out.

Questions and answers

What can I see with a 70mm refractor?
The Moon in good detail, Jupiter's cloud belts and moons, Saturn's rings, and the brightest clusters and nebulae. Faint galaxies and most deep-sky objects are out of reach.
What magnifications does it offer?
The 25mm and 10mm Kellner eyepieces give 16x and 40x; adding the 3x Barlow yields 48x and 120x. The highest setting is best on the Moon on steady nights.
Can I take photos with my phone?
Yes. The included smartphone adapter holds a phone over the eyepiece for simple Moon and planet shots. There is no tracking, so long exposures will blur.
Is it good for a child or complete beginner?
Yes. Setup is simple and the tripod is light. An adult should help with alignment and with the high-power eyepiece combinations.
Does it need batteries or a power source?
No. It is fully manual, with no motor drive or electronics, so it works anywhere without power.
How does it compare with a 90mm refractor?
A 90mm gathers more light and shows more planetary detail, but weighs more and usually costs more. The Sky View 70 is lighter and simpler to start with.

At Amazon, for $39.99, 20% under what the other stores charge, as of our latest check.
