Fifteen times the aperture in focal length
Sixty millimeters of lens at nine hundred millimeters of focal length is f/15. That one ratio explains most of this telescope.
A two-element achromat bends blue light slightly differently from red, and the shorter the tube, the more that shows as a violet fringe on bright edges. At f/15 the fringe is faint enough to ignore on the Moon, Jupiter and Venus.
The long focal length also gives high magnification with ordinary eyepieces, and it makes cheap eyepieces look better than they are. The cost is a narrow field and a tube close to a yard long.
Everything is 1.25 in
The three eyepieces and the diagonal are listed at 1.25 in (31.7 mm), the standard barrel size of modern amateur astronomy.
That matters more than any figure on the box. Kits with 0.965 in (24.5 mm) fittings lock their owner into a dead size; this one accepts any eyepiece, Moon filter or Barlow sold today. See eyepiece barrel diameters for why.
The magnification claim
The listing says up to 338x. That is the 4 mm eyepiece (225x) through the 1.5x erecting lens.
A 60 mm aperture is conventionally held to about 120x at the outside, and less on an unsteady night. Past that the image gets bigger and dimmer without showing more. The 20 mm eyepiece, at 45x, is where this telescope looks its best; the 12.5 mm, at 72x, is the planet eyepiece.
The weight, and the mount that comes with it
The whole kit is listed at 2.5 kg (5.5 lb), tripod and accessory tray included. It can be carried outside in one hand, which is the property that decides how often a first telescope gets used.
The mount is a simple alt-azimuth head: up-down and left-right, nothing to align. The maker publishes no slow-motion controls, so the tube is nudged by hand. At 72x and above, nudge, let go, and wait a second for the view to settle.
Who it suits
A first telescope for the Moon and planets, for a child with an adult nearby, or for a balcony where a heavier instrument would never come out. Anyone hoping to see faint galaxies should look at a wider aperture on the reflector shelf instead.
