The Explore Scientific 127mm f/6.5 Achromat Refractor is a large-aperture, entry-level five-inch refractor telescope (optical tube only) that delivers bright, detailed views of the Moon, planets, and star fields. Its air-spaced doublet achromatic optics and generous 127mm aperture gather plenty of light for rewarding visual astronomy at a great value.

Who it's for

Intermediate stargazers who want big refractor aperture for the Moon, planets, and wide-field views without a premium-apo price (a sturdy mount is required; sold separately). New to the hobby? See our beginner's telescope guide.

Frequently asked questions

What mount do I need?
At 127mm this is a sizable tube — use a sturdy alt-azimuth or equatorial mount rated for its length and weight for steady views.

Will I see color fringing?
Achromats show a little color around very bright objects like the Moon and Venus. It's a normal trade-off for the excellent value and aperture.

Is a mount included?
No — this is the optical tube only. Add a mount, diagonal, and eyepiece to observe.
