Optical Tubes

Sky-Watcher Evostar 72 APO

Sky-Watcher Evostar 72 APO Review: Recommended OTA

The Sky-Watcher Evostar 72ED isn’t the best small ED refractor available, but it’s certainly well-designed mechanically and has functional enough optics for astrophotographers to make use of it.
Explore Scientific AR127 Refractor

Explore Scientific AR127 Refractor Review: Not Recommended OTA

The Explore Scientific AR127 is a good mid-sized achromatic refractor, though it’s nowhere near as versatile as a more expensive ED doublet or triplet on account of its chromatic aberration.
Explore Scientific AR152 Refractor

Explore Scientific AR152 Refractor Review: Not Recommended OTA

The Explore Scientific AR152 certainly delivers if you want a big, fast f/ratio achromatic refractor, although why exactly you’d purchase such a thing is a different question given the compromises involved.
Apertura 6″ f/9 Ritchey-Chretien OTA

Apertura 6″ f/9 Ritchey-Chretien Review: Recommended OTA

Apertura’s 6” Ritchey-Chretien is a nice scope for galaxy imaging, but isn’t ideal for beginners.
Celestron EdgeHD 9.25

Celestron EdgeHD 9.25 Review: Recommended OTA

Celestron’s EdgeHD 9.25 is a great scope for visual astronomy and imaging, albeit at a rather high price and with limited use cases.
Celestron C6 XLT

Celestron C6 XLT Review: Recommended OTA

Celestron’s C6 XLT is one of the best Schmidt-Cassegrains in Celestron’s lineup and arguably the most versatile. It’s a travel scope, planet killer, astrograph, and works well for deep-sky viewing too.
Celestron EdgeHD 8

Celestron EdgeHD 8 Review: Recommended OTA

Celestron’s EdgeHD 8 is an even more versatile telescope than the original C8, with a design great for almost every type of astronomical viewing or imaging.
Explore Scientific ED80

Explore Scientific ED80 Essentials Review: Partially Recommended

Explore Scientific’s ED80 Essentials Triplet refractor is one of many small apochromatic refractors meant for astrophotographers in a crowded market. However, it’s not exactly the best for a number of unfortunate reasons which would be easy for the manufacturer to fix.
Sky-Watcher Skymax 150

Sky-Watcher Skymax 150 Review: Recommended OTA

Sky-Watcher’s Skymax 150 optical tube is a great scope for planetary imaging or viewing, or as a more general-purpose “grab n’ go” or travel scope - though for the former, some caveats exist.
Sky-Watcher Skymax 127

Sky-Watcher Skymax 127 Review: Partially Recommended OTA

Sky-Watcher’s Skymax 127 is a great “grab n’ go” or travel telescope, though it’s a bit limited compared to a slightly larger aperture offering and has some rather strange design flaws.
Orion StarBlast 62mm Travel Telescope

Orion StarBlast 62mm Travel Telescope Reviewed: Not Recommended

The Orion StarBlast 62mm Compact Travel Refractor Telescope isn’t particularly well-suited for both imaging or visual applications, though it is capable of both and of course tremendously compact.
Orion 180mm Maksutov-Cassegrain Telescope

Orion 180mm Maksutov-Cassegrain Telescope Review: Recommended OTA

Those who are interested in having a small, light, and portable planetary setup without having to use a Barlow lens or a long telescope should definitely consider the Orion 180mm Maksutov-Cassegrain Telescope, especially if they are looking for high-quality optics and a small central obstruction.
Celestron RASA 8”

Celestron RASA 8” Reviewed: Recommended OTA

The Celestron RASA 8” is an excellent astrophotography telescope provided you understand its limitations, use case, and complex design.
Explore Scientific 127ED OTA

Explore Scientific ED127 Essential Reviewed: Recommended OTA

The Explore Scientific ED Essentials 127ED isn’t the best imaging telescope out there but provides excellent views at the eyepiece and is a serviceable, if heavy, astrograph too.
Sky-Watcher Evostar 80ED

Sky-Watcher Evostar 80ED Review: Recommended OTA

The Sky-Watcher Evostar 80ED is an excellent telescope for visual astronomy as well as astrophotography without breaking the bank or requiring a bulky and expensive mount to be used.
Orion ED80

Orion ED80 Telescope Review (Now Discontinued)

A decent ED doublet refractor, the Orion ED80 was great optically but its mediocre mechanics made it a harder sell than some competing instruments, particularly for imaging use.
Celestron C9.25 XLT

Celestron C9.25 XLT Reviewed: Highly Recommended!

While certainly a bit of a niche telescope (as with any Schmidt-Cassegrain) the Celestron C9.25 XLT is probably the best SCT on the market and has outstanding optical performance.
Celestron C11 XLT

Celestron C11 XLT Review: Recommended OTA

The Celestron C11 XLT is a big scope with huge capabilities. However, it’s not for everyone.
Celestron C8 XLT

Celestron C8 XLT Review: Recommended OTA

While certainly a bit of a niche telescope (as with any Schmidt-Cassegrain) the Celestron C8 XLT is probably the best SCT on the market and has outstanding optical performance.
Orion Apex 127mm Maksutov-Cassegrain

Orion Apex 127mm Maksutov-Cassegrain Reviewed: Partially Recommended OTA

The Orion Apex 127 Maksutov-Cassegrain telescope was a great choice for astronomers on the go who wanted a lightweight, portable scope for viewing bright targets, though it didn't offer the best value for the money.
Orion 8" astrograph

Orion 8” f/4 Astrograph Telescope Review (Now Discontinued)

The Orion 8” f/4 Newtonian Reflector Astrograph was a decent imaging telescope and provided me great views at the eyepiece as well. Sadly, Orion went out of business in 2024.
Explore Scientific AR102

Explore Scientific AR102 Reviewed

The Explore Scientific AR102 is a decent telescope, though as an achromatic refractor it’s limited in utility as well as overall value for the money.
