This telescope lives for the planets.

An f/10 focal length built to magnify. Where fast scopes sweep wide, this one holds a single planet rock-steady at high power — a telescope for the patient observer on a steady night.

Sweet spot 150–250×Loves steady seeing
The view people remember

Jupiter and its four moons.

Cloud belts stripe the disk and the Galilean moons shift positions night to night — on a steady evening the Great Red Spot rotates into view.

02In plain English

What These Numbers Mean

203mm · f/10 · 2032mm FL · Alt-Az GoTo
Aperture
203 mm (8 inch)
Eight inches of mirror gathers about 840 times more light than your eye. That is enough to split tight double stars, resolve the cores of globular clusters, and show cloud bands on Jupiter alongside the Cassini division in Saturn's rings.
Focal length
2032 mm
Two metres of focal length naturally favours planets, the Moon, double stars, globular clusters and small galaxies. Wide nebulae such as the North America Nebula need a focal reducer or a different telescope entirely.
Focal ratio
f/10
A slow f/10 delivers high-magnification, high-contrast views of the Moon and planets with forgiving eyepiece requirements. The cost is a narrow field and dimmer deep-sky views than a fast scope of the same aperture.
Optical design
Schmidt-Cassegrain
The folded light path packs 2032 mm of focal length into a tube about 43 cm long, which is the only reason an 8 inch telescope can sit on a single fork arm. The sealed tube stays clean and holds collimation, in exchange for a real cooling period.
Finding system
SkyAlign GoTo
Point the scope at any three bright objects and SkyAlign works out the whole sky, then slews automatically to more than 40,000 targets. You can find galaxies without knowing a single constellation.
Mount
Motorised single-fork alt-az
The motor tracks objects so they stay centred at high power, which is a real advantage over a manual Dobsonian. The single-arm fork on a tripod adds some vibration, and alt-azimuth tracking rules out long-exposure astrophotography.

Editor’s Take

The 8SE put GoTo in a lot of first-time hands and is still the default do-everything computerised scope. GoTo means the mount finds and tracks for you: align on two bright stars, pick a target, and its motors slew there and follow it. The 8-inch Schmidt-Cassegrain ("SCT") folds a long 2032 mm focal length into a compact tube on a single-arm alt-az fork, so you get serious aperture for high-resolution Moon, planets and real deep-sky detail, carried out in two pieces. As a point-and-explore visual scope, few first telescopes are as beloved.

Community

Used in these setups.

Real builds from the community that include this product.

White-Light Sun Watcher

Featured

Solar observing in white light. A full-aperture filter fits over the front of the C8 and rejects all but a whisper of the sunlight before it enters the telescope, leaving a crisp white disc with sunspot groups, granulation and the darker limb. It is the only target that is up when you are, and the only one that changes visibly from day to day.

Planetary Imaging Setup

Featured

High frame-rate planetary imaging. The C8 gives 2032mm of focal length and the 2x Barlow doubles it, putting the image at roughly f/20 — about where the ASI662MC's 2.9-micron pixels stop throwing away detail. The camera runs fast and clean, which is what lets you keep only the sharpest frames.

Planetary Specialist

Featured

High-magnification configuration for Jupiter, Saturn and Mars. The C8 SCT supplies the long focal length; the 12mm, 7mm and 2x Barlow give you 169x, 290x and 338x so you can match the magnification to the night instead of hoping one eyepiece fits every sky.
