Overview
At 80mm aperture and f/7.5, this EACONN refractor gives you a genuine step up in light-gathering over the smaller 60mm scopes cluttering this price range. The fully coated optics help maximize contrast, which matters most when you are scanning the Moon's craters or trying to split Jupiter's cloud bands from a backyard. The two included Kellner eyepieces deliver 30x with the K20mm and 66x with the K9mm, both reasonable magnifications for a scope of this focal length.
Pushing much beyond 66x on a 600mm focal length will soften the image, so keep expectations realistic for deep-sky work. This is a lunar and planetary instrument first. The 5x24 finder scope is modest but functional for bright targets.
At 0.84kg the tube is genuinely portable, and the included backpack makes transport straightforward. The alt-azimuth mount with scale markings helps with basic positioning, though it lacks the smooth slow-motion controls found on pricier mounts. For a first telescope aimed at the Moon, Saturn's rings, and double stars, this is a solid and honest option at $89.99, backed by a strong base of nearly 2,000 user reviews averaging 4.4 out of 5.

Amazing telescope to use for beginners! Easy to assemble, really good lens and amazing view! Totally worth getting for such a low price!
Let the night sky adventures begin!!! Impressive performance, this EACONN telescope makes a near perfect gift for the person who has everything. There's a whole new world out there to see. This telescope is far better than expected and great value for the price. It's been a game changer. Really cool...
Based on the reviews of children enjoying this telescope and the price point i wasn’t expecting much. I was pleasantly surprised when the telescope arrived. It is larger than I expected, has an adjustable 3 level tripod, a phone mount to take photos, includes a travel case and is a great entry level...
