I also noticed terms like “doublet” and “triplet” being used, so I investigated further. When the very first frame appeared on the back of my DSLR display screen, my jaw hit the floor. At that time, I had no idea that this telescope would be my ticket to a lifelong ride in the world of astrophotography. At the time of writing, I’ve owned this telescope for almost 7 months. He had recently posted another exquisite photograph using the ED80, that showcased the incredible imaging capabilities of this triplet APO. I fitted a Skywatcher remote focusser but it did need a bit of Engineering to do it. True APO optic and are diffraction limited at.25PV or better. The dual-speed, Crayford-style focuser is ultra-solid and tightly locks my DSLR camera into place while imaging. 100 minutes of exposure time with a Nikon D5100, First shot of M31 with my ES ED80. When not in use, it all packs away securely in the padded metal hard-case. While this scope can’t resolve the finer details as well as those larger instruments can, it was still a very impressive sight considering the small aperture and short focal length. Explore Scientific ED80 Review When I first began taking pictures of deep-sky objects through my telescope, they were shaky images with bloated football stars and poor focus. My early deep sky images using an Explore Scientific ED80 Triplet APO. This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion … The model available from Explore Scientific had the specifications I was looking for, at a price I was comfortable with for my newfound hobby. I think that once you get used to the pinpoint stars and sharpness of an Apo, it’s hard to accept anything less. The diagonal also features compression rings rather than screws to hold your eyepieces in place, so you won’t marr your eyepieces using it. The visual performance of this scope is excellent, especially when viewing bright planets or the moon. FACEBOOK: LINKEDIN: TWITTER: INSTAGRAM: ©2019. Overall, construction seems solid with a great finish. Everything was solid out of the box. Explore Scientific ED APO 80mm f/6 Essential - part of the Explore Scientific Essential series. They say the best telescope is the one you use the most, and my ED80 has been used for more hours under the stars than I care to admit! Deep sky objects within its reach show fantastic contrast. The HOYA extra-low dispersion (ED) glass is a trait found in a much more expensive refractor telescope. Be it with a DSLR or my lunar imager (ZWO ASI120MC-S), it delivers incredible images and reveals subtle detail that only my larger 8 SCT can come close to matching. The moon – 58% waxing gibbous shot with a Nikon D750. The Explore Scientific ED80 Essential Edition is a value oriented member of the 80mm apochromatic refractor class priced only slightly higher than competing doublet refractors. From the moment that first exposure of the Orion Nebula appeared on the camera screen of my Canon 450D, I was in love with the image quality produced by the Explore Scientific ED80. The colour and contrast produced was just unmatched by those larger scopes. I tightened them up, only to have them loosen up again after a couple more uses. Moving it as far forward as I can, it also blocks the focuser rotation (for image framing) from being able to be rotated more than a few degrees in either direction. It would appear there’s a slight issue here with the allowed tolerances for the threading. I am so happy with the performance of the 80mm version, that upgrading to the Explore Scientific ED102 Carbon Fiber version was a no-brainer. 1 hour 45 minutes of integration time shot with a Nikon D5100. Collimation of such an instrument is a delicate task that’s not easily achieved. The diffraction-limited optics are appreciated when exploring the lunar terrain or using a high-powered eyepiece to view Saturn’s rings. A common question I get is about the finderscope bracket on the Explore Scientific ED80. It’s not a show stopper, but it’s something that definitely could have been done better. The Explore Scientific ES80 "Essential Series" refractor uses a premium Hoya FCD-1 ED glass element and state-of-the-art optical multicoatings in its apochromatic air-spaced ED triplet optics.
