80mm (3.1”) f/600 ED Apochromatic Refractor
The new EVOSTAR DS-PRO Series ED Apochromatic refractors in their stunning Black-Diamond livery, house premium optics of the same quality and performance level as our now legendary Equinox series, making them superb instruments for both imaging and visual observations.
Apochromatic Refractors, due to their unobstructed, text-book like diffraction patterns, produce the sharpest, highest quality optical imaging available, bar-none, aperture for aperture, of any telescope optical system.
These high-end telescopes all feature a doublet objective lens. One element is made from premium Japanese Ohara FPL-53 Extra-Low Dispersion (ED) glass, which virtually eliminates chromatic aberration to deliver true colour reproduction. Top quality glass is utilized for the Crown element.
Each air-to-glass lens surface has exotic anti-reflection metallic coatings applied, to ensure optimum light through-put of approaching 99.5%!!
The proprietary Sky-Watcher “Metallic High-Transmission Coatings” (MHC) are the finest photon anti-rejection coatings in their class.
An in house Zygo interferometer test & report is available with this telescope. Click here to read about the interferometer test in more detail. There are various packages available on this model. Please select from the packages above.
The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. We will aim to provide 0.95 Strehl or higher.

I have used this with my 2600MM, and the results have blown me away. I canít believe the quality of the glass for the price. The depth of detail I picked up in Melotte 15 was very good-even for the focal length of just over 500 (using with the 0.85 reducer and FF) exceptional quality, and exceptional service from the guys at RVO, always. Will always be back for all of my astro needs! Youíre the best!
