Overview
At 70mm aperture and 400mm focal length, this refractor gives beginners a genuine look at the night sky without overwhelming complexity. The two included eyepieces, 12.5mm and 20mm, provide magnifications of 20x and 32x, which is a reasonable range for a first scope. At these magnifications, you can expect clear views of lunar craters, the phases of Venus, and possibly the moons of Jupiter on a steady night.
The fully coated optics help maximize light transmission, which matters more as targets get dimmer. The f/2 focal ratio is quite fast for a refractor, which can introduce some chromatic aberration on bright objects like the moon, so colors may appear slightly fringed at the edges. The included 5x24 finder scope makes locating targets considerably easier for beginners.
Terrestrial use is equally practical, and the adjustable tripod handles both seated and standing positions. The phone adapter is a fun addition for capturing quick snapshots of the moon. Weighing just over 3kg and priced under $60, this scope suits families looking for a low-commitment entry point into astronomy rather than a long-term performance instrument.

A great telescope for the beginners. Simple to use, it has clean lens and good accessories. Gave us a goosebump seeing craters on the moon! It took us a few tries to adjust the lens, but once we did, it’s exciting to looking at the moon and stars every clear night. The image quality is incredible. T...
First, the most important thing: the optics are fantastic! Sky is crystal clear, under ideal conditions, through the 20mm eyepiece. I was blown away that a $30 telescope could be that sharp. Either we won the lottery with out particular scope or this thing has way better optics than it has any right...
