Confusing Catadioptric Cassegrain Telescopes

1. Celestron NexStar Evolution 8

The NexStar Evolution 8 combines compact design with powerful performance, making it a standout in the world of catadioptric telescopes. Its 8-inch (203.2 mm) Schmidt-Cassegrain optical system offers a 2,032 mm focal length (f/10) and supports magnification up to 480×. The package includes two Plössl eyepieces: a 40 mm (51×) and a 13 mm (156×).

With StarSense AutoAlign technology, setup is straightforward – calibration is automated. The telescope also features built-in WiFi, allowing users to control it through Celestron’s SkyPortal app, available on both iOS and Android. Astronomy expert Gemma Lavender highlights its detailed sky tour capabilities.

The onboard computer holds a database of 40,000 celestial objects, making it easy for users to locate and track targets. Plus, the LiFePO₄ battery provides over 10 hours of operation, perfect for lengthy observation sessions.

Priced at $2,262, the NexStar Evolution 8 offers premium optics paired with user-friendly controls. For those interested in astrophotography, an optional wedge enables long-exposure imaging. As Space.com notes:

"Operation of its WiFi technology is seamless, while the computerized GoTo mount boasts exceedingly high performance".

Up next, the Celestron Advanced VX 8 EdgeHD delivers enhanced aperture and clarity for those focused on imaging.

2. Celestron Advanced VX 8 EdgeHD

The Celestron Advanced VX 8 EdgeHD pairs Schmidt-Cassegrain EdgeHD optics with a reliable equatorial mount. With an 8-inch (203.2 mm) aperture and a 2,032 mm focal length, it delivers sharp, clear star images across the entire field by reducing field curvature and off-axis distortions. Its folded-path design ensures high-quality visuals throughout.

This telescope offers three f-stop modes: f/10 (native), f/7 (with a reducer), and f/2 (using Fastar/HyperStar). The optical tube includes mirror locks to maintain focus during long exposures and HEPA-filtered vents to speed up cooldown times.

The Advanced VX mount, compact yet sturdy, supports up to 30 lbs (13.6 kg) of equipment and includes features like:

Dual saddle plate for CG-5 and CGE-style dovetails
All-Star Polar Alignment for quick setup
Nine slew speeds, reaching up to 4° per second
NexStar+ database with over 40,000 celestial objects
Ports for hand control, autoguiders, and dual AUX connections

TelescopicWatch reviewer Zane Landers highlights its limitations:

"The Celestron Advanced VX 8" EdgeHD may seem tempting as an all-in-one versatile imaging and visual telescope, but the Advanced VX mount is just not up for the job of long-exposure astrophotography and simpler/cheaper setups exist for visual and planetary imaging use."

With a light-gathering power 843 times greater than the human eye and a limiting stellar magnitude of 14, the package includes a 40 mm eyepiece, a 1.25″ star diagonal, and a 9×50 finderscope. StarBright XLT coatings enhance light transmission, while Celestron’s PWI Telescope Control Software adds precision and advanced mount modeling.

Priced at $2,899.99, this setup is great for visual and planetary imaging but isn’t ideal for deep-sky, long-exposure astrophotography. The mount head (17 lbs/7.7 kg) and tripod (18 lbs/8.2 kg) are easy to transport, and the adjustable stainless-steel legs (44–64″) ensure stability.

Next up: the Sky-Watcher Skymax 150 PRO offers high aperture in a compact design.

3. Sky-Watcher Skymax 150 PRO

The Sky-Watcher Skymax 150 PRO is built with a Maksutov-Cassegrain design, offering precise optics in a compact setup. With a 150 mm aperture and an 1,800 mm focal length (f/12), it provides sharp, high-contrast views, making it an excellent choice for detailed planetary observations. Its compact size and long focal length strike a good balance between portability and performance.

The mirrors are coated with RAQ™ for up to 94% reflectivity, while the corrector plate features MHTC™, which reduces chromatic aberration. This combination results in sharper planetary views compared to standard Schmidt-Cassegrains with similar focal ratios.

The telescope’s tube is made of sturdy aluminum, ensuring durability. Included accessories – such as a 2″ 28 mm eyepiece, a 9×50 finderscope, a 2″ diagonal, and a V-style dovetail plate – provide everything needed for basic observing sessions.

Up next: the Intes MN61, a compact option with high-quality optics for deep-sky exploration.

4. Intes MN61

The Intes MN61 stands out as a solid choice for deep-sky enthusiasts, offering a well-crafted Maksutov-Newtonian design. This setup combines a front corrector lens with a Newtonian mirror, delivering sharp and detailed deep-sky views. It features a 61 mm aperture, a 700 mm focal length (f/11.5), and high-quality optics housed in a compact 17-inch tube.

The telescope’s RAQ-coated mirrors provide 94% reflectivity, while the multi-coated meniscus corrector lens reduces chromatic aberration. Together, these features ensure high contrast, making it great for observing planets and the Moon [6]. Like the Skymax and Celestron models, its lightweight and compact design make it easy to use both at home and in the field.

Priced at $1,499, the package includes a sturdy German equatorial mount, a 25 mm Plössl eyepiece, and an 8×50 finder scope. Weighing just 22 lbs, it’s one of the more portable telescopes in its category [6]. The precise tracking and stable mount also make it a strong option for both visual observation and astrophotography.
