Celestron CGEM II 800 Schmidt-Cassegrain Telescope

Product overview

The Celestron CGEM II 800 Schmidt-Cassegrain Telescope pairs an 8-inch Celestron SCT optical tube with the CGEM II computerized German equatorial mount. It is a capable GoTo telescope package for visual observing, lunar and planetary imaging, and intermediate deep-sky astrophotography.

Who Is This Product Best For?

This system is best for intermediate astronomers who want a versatile 8-inch telescope with a stronger mount than smaller entry-level packages. It suits visual observers, planetary imagers, and astrophotographers who want a long focal length SCT platform.

Why Choose This Product?

• 8-inch Schmidt-Cassegrain optical tube provides strong light gathering in a compact design.
• 2032mm focal length is useful for planets, the Moon, galaxies, and compact deep-sky objects.
• CGEM II mount offers GoTo tracking, autoguider support, and a solid equatorial imaging platform.
• StarBright XLT coatings support good visual contrast and imaging throughput.
• A versatile telescope package for both visual observing and imaging.

Recommended Uses

• Lunar and planetary observing
• Planetary imaging
• Visual deep-sky observing
• Small galaxy and planetary nebula imaging
• Backyard or semi-portable GoTo setups

Compatibility and Accessory Notes

Use appropriate SCT adapters, a camera, guide system, and power supply for imaging. A focal reducer can be useful for wider-field imaging, while Barlows are useful for planetary imaging.

Important Limitations

Long focal length deep-sky imaging requires accurate polar alignment, guiding, and careful balance. This is not the easiest first astrophotography telescope for wide-field targets.

Frequently Asked Questions

Is this good for beginners?

It is manageable for a motivated beginner, but best for intermediate users.

What is it best used for?

It is best for lunar, planetary, and compact deep-sky observing or imaging.

Is it for visual observing or astrophotography?

Both, with accessories required for astrophotography.

Does it require additional accessories?

Imaging requires a camera, adapters, guiding equipment, and stable power.

When should it not be recommended?

Do not choose it as a simple wide-field beginner imaging rig.

Our Recommendation

Ontario Telescope recommends this package for customers who want a strong 8-inch SCT on a capable mount. Choose it for flexibility; choose a shorter focal length refractor or astrograph for easier wide-field imaging.
