Guide to Refractor Optics – Choosing the Best Telescope for …

1. Apertura 90mm Refractor Review

Pin

The Apertura 90mm is a high-quality apochromatic triplet refractor designed for both visual astronomy and astrophotography. Its 90mm (3.54") aperture and 540mm focal length offer an excellent balance of light-gathering power and portability. This design prioritizes clear, unobstructed light paths and sharp star images.

At its core is an FPL-53 apochromatic glass objective lens, which minimizes chromatic aberration. This means stars remain sharp and free from distracting color fringing, a common issue in many other refractors. Below, we dive into how these features translate into practical performance.

The telescope features a dual-speed 2.5" rack-and-pinion focuser with a 10:1 fine adjustment capability. This allows for precise focusing, which is especially important for high-magnification observations. Additional features include a rotatable focuser for aligning cameras, a retractable dew shield, a 1x field flattener for full-frame sensors, and a built-in 2" filter thread.

"This is the single best refractor I have used in my astrophotography career… the build quality is exceptional… a perfect refractor in all instances." – Teagan G., High Point Scientific Gear Expert

With its f/6 focal ratio, the Apertura 90mm is versatile enough for wide-field views of deep sky objects as well as detailed observations of the Moon and planets. Its limiting magnitude of 12.5 allows it to capture faint celestial objects under dark skies. Weighing 9.8 pounds, the optical tube assembly requires a sturdy mount, but its solid construction makes it worth the investment.

A 4.8-star rating highlights its excellent color correction and compatibility with full-frame sensors, making it a great choice for those who want premium performance without the bulk of larger instruments. The Apertura 90mm stands out as a strong performer in the refractor telescope category.

2. Celestron Inspire 80AZ: Entry-Level Option

The Celestron Inspire 80AZ pairs an 80mm aperture with a 900mm focal length, delivering reliable optical performance for both stargazing and daytime viewing. Designed with beginners in mind, it’s easy to use and offers a solid starting point for newcomers.

This telescope’s f/11 focal ratio is particularly suited for detailed views of the Moon and planets, though some slight color fringing may occur. The included 20mm (45x) and 10mm (90x) Kellner eyepieces provide versatile magnification options for different viewing scenarios.

The Inspire 80AZ comes with several useful accessories. Its StarPointer® Pro red dot finderscope makes it easier to locate objects in the sky. A smartphone adapter allows you to capture images, while the built-in red LED flashlight is handy for maintaining night vision. The telescope is simple to set up – no tools needed – and comes with an adjustable tripod that extends from 32" to 51". The Alt-Az mount offers smooth movement and precise control with its clutch mechanism.

Priced at under $300, the package also includes Celestron’s Starry Night Software, the SkyPortal App, and an erect image diagonal, making it suitable for both celestial and terrestrial observations.

The Sky-Watcher Esprit 100ED is a refractor telescope designed for deep-sky imaging. With a 100mm aperture, 550mm focal length, and f/5.5 focal ratio, it delivers exceptional optical performance for astrophotography enthusiasts.

This model uses Schott-BK-7 and FPL-53 ED glass elements, paired with Sky-Watcher’s Metallic High-Transmission Coatings™ (MHTC). These features reduce chromatic aberration and improve light transmission, ensuring sharp, high-contrast images. Additionally, an internal knife-edge baffling system helps eliminate stray light and reflections. The package also includes several imaging accessories to enhance its functionality.

The 3.4" rack-and-pinion focuser features a Helinear track for precise adjustments with minimal image shift. Its rotating design allows for flexible framing, making it ideal for various astrophotography setups.

Accessories included with the telescope:

• A 2-element field flattener for sharp star images
• An M48 camera adapter compatible with Canon DSLRs
• An 8×50 right-angle finderscope
• Tube rings with a Losmandy-style D series dovetail
• A padded hard case for secure storage and transport

Astrophotographers have praised the Esprit 100ED for its performance. In October 2024, Michael B., an experienced astrophotographer, reported flawless results using the telescope with ZWO 294 and ZWO 2600 OSC cameras, particularly with the ZWO 294 right out of the box. For optimal results, maintain a 63mm backspacing distance from the field flattener’s last lens element when using astrophotography cameras.

The telescope has received a 4.6/5 star rating from users. While its image quality and sturdy build are often highlighted, some users have mentioned that the included rings could provide better support for the optical tube assembly (OTA) at certain angles.

4. Orion GoScope III 70mm: Travel Model

The Orion GoScope III 70mm is a lightweight refractor telescope designed with portability and ease of use in mind. With a 70mm aperture and a 400mm focal length (f/5.7), it delivers sharp views, whether you’re stargazing or observing landscapes during the day.

This telescope is perfect for travel, weighing just 4.25 lbs and coming with its own backpack for easy transport. The adjustable aluminum tripod ranges from 17.75 inches to 43.5 inches, allowing for comfortable viewing in various positions.

Included accessories make it even more user-friendly: two anti-reflection coated 1.25-inch Kellner eyepieces (20mm for 20x magnification and 9mm for 44x magnification), a 45-degree correct-image diagonal, a 5×24 finder scope, and the Orion MoonMap 260 for detailed lunar exploration.

Users have praised its convenience and performance:

"Best bang for the buck travel telescope complete with backpack. My only complaint would be average eye piece and flimsy tripod. But what can you ask for more at this price. It’s a fantastic beginner telescope." – Min P.

To get the most out of this telescope, start with the 20mm eyepiece to locate your target, then switch to the 9mm for a closer look. It’s particularly well-suited for observing the Moon and planets, making it a great choice for beginners or as a portable second telescope.

In August 2019, a user named Roger improved its performance by pairing it with a Celestron Photographic & Video Tripod and an Orion Tritech LT-1 Travel Tripod, enhancing both lunar and stellar observations.
