Sky-Watcher Pro 80ED APO overview

  • 1Description

The ProED 80mm f/7.5 Doublet APO Refractor from Sky-Watcher features a doublet apochromatic lens system with Extra-low Dispersion (ED) glass and Sky-Watcher's proprietary photon anti-rejection Metallic High-Transmission Coatings (MHC) on all air-to-glass optical surfaces. This combination of glass, lenses, and coatings virtually eliminates chromatic aberrations for clear and bright high-contrast images with true color rendition. This is a versatile optical tube assembly (OTA) that is well suited for wide-field astronomical observation of prominent nebulae, star clusters and galaxies, or can be used as an astrograph for sky photography, a terrestrial spotting scope or telephoto lens.

A mounting cradle-ring clamps over OTA and allows the user to adjust the orientation and position of the scope relative to the mount to optimize viewing comfort and balance, while avoiding interference with other equipment. The scope is offered without a mount or tripod, but a Vixen-style dovetail plate makes it compatible with any alt-az or equatorial mount with a Vixen-style saddle.

Its two-speed Crayford-style focuser helps make fine-focusing fast and precise without backlash. The ProED comes with several accessories to help you get observing faster and easier. First, are two long eye relief eyepieces that produce 30 and 120x magnification, a 90° star diagonal for more comfortable viewing, and a large 8x50 erect-image finderscope to make finding your celestial objects faster and easier. Finally, Sky-Watcher provides a foam-lined aluminum carrying case to safely store and transport the OTA.

    Sky-Watcher Pro 80ED APO reviews

    ProED 80mm f/7.5 Doublet APO Refractor (OTA only) is rated 4.3 out of 5 by 4.
    Rated 5 out of 5 by from First night...Blown away My intent was to capture full disc sun and moon shots with my Orion All In One camera and the reducer/corrector for this OTA. After contacting Sky-Watcher They informed me that setup would not work, but an Orion .5x focal reducer should achieve my desired shot with the camera and this OTA. Tho just barely I'd had this in my wish list for several months and it went on sale So I finally pulled the trigger and it arrived 2-9-17. One day before a Lunar Eclipse. Took it out that night (tonight) and the words I have I can't write in this public space...I'm beyond ecstatic to say the least. A solar filter and I'm ready for the Solar Eclipse in August.

    Rated 4 out of 5 by from Excellent scope. The ED glass on this scope has no chromatic aberration that I could detect. Prime focus unmodified DSLR images had zero blue fringes around good round stars. Focus is very tight, no distortions I could see and photographically there was only very slight coma towards the field edge and this seen only by really blowing up the image. The crayford focuser is excellent. It is smooth and can take the camera and diagonal weight without shifts. I could not move it even with a push by hand. The dual speed action is perfectly judged, the knobs conveniently large for gloved hands. The included 2 inch dielectric diagonal is huge and would guarantee no vignetting and will accommodate the widest field eyepieces. Nice right angled finder. Two included eyepieces are good. Aluminum case is a nice touch. A great scope and as good as anything retailing for twice the price.

    Rated 5 out of 5 by from Beautiful Scope! Scope arrived super fast and well packaged. You get a lot of extras with this scope which is really nice. (Love the aluminum case!) This scope is well designed and really is a beauty. I had read reviews about the focuser being lower quality but I have found this not to be the case. Focusing is super smooth and the optics are top notch. You really can't beat the price! I am completely satisfied with my purchase and cannot wait to start using this for astrophotography. Well done Skywatcher and B&H!

    Rated 3 out of 5 by from Not for me. The OTA was too heavy. The included eyepieces and case seemed to be pretty nice and the optics were good. The RACI was low quality. I had trouble balancing the OTA with a 2 eyepiece. The focuser was not smooth at all, which was the primary reason that I ultimately returned this OTA and bought a different one. This is decent budget OTA, but not what I was anticipating.
