Great first astrophotography telescope

Overall this is a great triplet refractor telescope. You do need a field flattener for imaging, but not needed for visual observing. There is very little chromatic aberration. The views are crystal clear and contrast is great. The focuser gives fine control for sharp focus and it stays that way for the night. To achieve focus with a DSLR you are going to use one or both of the included spacers. I use one spacer. This gives a focus with the DSLR at about 40mm focuser travel and about 5mm with the included star diagonal for visual observing. The problem with using a spacer is it does not fit in the bag nor the box anymore without modifying the foam padding for the box.The telescope comes with a proprietary finder scope base only. The aftermarket community has different base plates for the standard dovetail style everyone else uses. At this price point, a finder scope should be included. A red dot would be good for this scope due to its wide field of view.

ED 80 is a winner!

By GREG C.

Great scope with excellent views.

With the Essential ED80 80mm Air-Spaced Triplet Apochromatic Refractor, Explore Scientific has crafted a top-tier telescope that combines traditional design with modern technology. This high-quality refractor features an air-spaced triplet optical design housed in a robust, adjustable lens cell, ensuring durability and precision.

The heart of this telescope lies in its optics. Crafted from genuine Hoya extra-low dispersion (ED) Dense Fluor Crown (FCD1) glass, the lenses offer superior sharpness and color correction. These elements are shaped and polished by experienced craftsmen, forming the foundation of this true APO refractor. All Explore Scientific Air-Spaced Triplet APO Refractors are diffraction-limited at .25PV or better, guaranteeing high-quality, bright, and high contrast images with minimal light scatter.

The ED80 refractor is further enhanced by EMD (Enhanced Multi-layer Deposition) Coatings. This proprietary coating, applied in multiple layers to all optical surfaces, eliminates light scatter and maintains high image contrast. This, combined with the installation of multiple baffles in the optical tube, ensures that unwanted stray light is masked and deflected, enhancing the contrast even further.

The telescope also features a deluxe two-speed Crayford-style precision focuser. This focuser, standard on this model, allows for fine adjustments and a lock to obtain and hold perfect focus. This feature is particularly useful on clear nights when you want to push the magnification to the limits and explore celestial bodies like Saturn's Rings in greater detail.

In summary, the Essential ED80 80mm Air-Spaced Triplet Apochromatic Refractor from Explore Scientific is a high-quality, durable telescope that offers superior optics, enhanced contrast, and precise focus control. Whether you're a seasoned astronomer or a beginner, this refractor is a valuable addition to your stargazing equipment.

Explore Scientific ED80 Features

  • The Explore ED80 Essential Edition telescope comes with a white aluminum tube with black accents
  • Explore Scientific Air-Spaced Apochromatic Triplets have true APO optic and are diffraction limited at .25PV or better
  • Genuine ED glass from Hoya Japan is used on all ED APO Triplets at Explore, for superb quality and light throughput
  • Enhanced Multi-Layer Coatings (EMD) are deposited on optical elements to boost contrast and eliminate light scatter; and contrast is further enhanced with the installation of matte black knife-edge baffles in the optical tube assembly
  • While refractors seldom require additional collimation after initial factory adjustment, the lens cell design allows for consumer collimation. Sending your ED80 Triplet off to the factory is always an option, but is not required
  • 80mm models come with a heavy-duty 2" dual-speed rotatable focuser
  • The included 2" diagonal has a precision-polished mirror with enhanced 99% dielectric coatings. A 1.25" compression ring adapter is part of this package
