Review ASTROTECH Astro tech Ed Triplet Refractor Mint

The Astro-Tech AT80ED-TR plet Refractor is a high-performance, Triplet Apochromatic telescope designed for dedicated astronomers and astroimagers seeking optimal image quality and resolution. This particular model, with its 80mm objective lens, offers an excellent balance between light grasp and compactness.

The heart of this telescope lies within its triplet apochromatic design, featuring an H-Omega flint glass triplets on each side of the schmidt-cassegrain secondary mirror. This innovative design eliminates chromatic aberrations, ensuring precise, true-to-life color representation in all celestial objects.

The primary mirror, crafted from high-quality Corning 7051 Optical-Grade Pyrex glass, boasts a paraboloidal shape focused on delivering exceptional optical precision. This mirror faithfully transfers light and data from the objective lens to the secondary mirror, creating an exceptionally clear, sharp, and high contrast image.

The secondary mirror, constructed with high-density aluminum, possesses a small, robust, and evenly figured shape. This design also ensures minimum scatter and light loss, ultimately contributing to a clearer, more defined image. The secondary mirror has a reflective coating made of Aluminum, which has high reflectivity in the visual wavelength, allowing the maximum amount of light to be reflected.

The AT80ED-TR triangle-tube tubes consist of 6061-T6 aluminum, offering both structural rigidity and minimal thermal expansion for increased imaging stability. This 4-element design includes tension clamps and locking collars to securely hold the secondary mirror in place.

The telescope boasts an adjustable focus system, including a 12-inch 1.25-inch Crayford-style focuser, which provides an impressive 10:1 reduction ratio and a generous 65 mm clear aperture. This focuser enables fine-grained focusing with little to no backlash and is ideal for visual observations or astrophotography applications.

The AT80ED-TR comes with a Vixen-style dovetail for secure installation on a mount or fork arm. Additionally, this refractor comes with a 2-inch auxiliary focus drawer, allowing the accommodation of 2-inch eyepieces. Furthermore, this telescope includes a generous 1.5-inch star diagonal, enhancing the field of view and creating a comfortable viewing experience, whether observing at high magnifications or wide fields of view.

The Astro-Tech AT80ED-TR triplet refractor showcases superb light-gathering ability, color correction, and contrast levels. It promises awe-inspiring views of celestial wonders like deep sky objects, planets, and the Moon, with its unparalleled sharpness and incredible detail.

The Astro-Tech AT80ED-Triplet Refractor is a popular choice among amateur astronomers for its excellent optical performance and affordable price. Here are some pros and cons of investing in this telescope:

1. High-quality optics: The AT80ED-Triplet Refractor features a triplet apochromatic design that corrects for chromatic aberration, resulting in sharp and clear images.

2. Lightweight and portable: With a weight of only 9.5 pounds, this telescope is easy to transport and ideal for astrologers who prefer observing from various locations.

3. Wide field of view: This telescope offers a generous 48-degree field of view, providing ample coverage for exploring vast regions of the night sky.

4. Affordable: The AT80ED-Triplet Refractor is competitively priced compared to other telescopes that offer similar optical performance.

5. Easy to use: Its simplicity makes it an excellent choice for beginners, requiring minimal setup time and effort to achieve satisfying observing sessions.

1. Limited magnification: With its 80mm aperture, the AT80ED-Triplet Refractor might not offer the same magnification capabilities as larger telescopes. This could affect the ability to observe fainter, more distant objects.

2. Needs additional equipment: To make the most of this telescope, you'll need to invest in various accessories like a good quality eyepiece and a mount for stable observation.

3. Some users report problems with collimation: Although a common issue with many Newtonian-type telescopes, some users have mentioned that the AT80ED-Triplet Refractor may require frequent collimation adjustments for optimal performance.

The Astro-Tech AT80ED-Triplet Refractor is a worthy investment for those seeking a high-quality, portable, and affordable refractor telescope. Its excellent optics, wide field of view, and ease of use make it popular among astronomers, both beginners, and experienced observers. However, it may not provide the same magnification capabilities as larger telescopes, and some users have reported issues with collimation. With the necessary accessories and proper maintenance, this telescope can offer many hours of satisfying skywatching experiences.

For those looking for a versatile, high-performance, and portable telescope at an affordable price, the Astro-Tech AT80ED-Triplet Refractor is an excellent choice. It is suitable for a wide range of observing interests and experience levels, making it a wise investment for any astronomer.
