The ED80 80mm f/6 Essential Apochromatic ED Triplet Refractor Telescope from Explore Scientific features a triplet apochromatic lens system with Extra-low Dispersion (ED) glass and Explore Scientific's proprietary anti-reflection EMD fully multicoated optics. This combination of glass, lenses, and coatings virtually eliminates chromatic and spherical aberrations for clear and bright images without distortion across the entire field of view, with true color rendition. This is a versatile optical tube assembly that can be employed as a simple grab-and-go primary telescope, as a large finderscope mounted to a larger scope such as a Dobsonian, or set up on a dual-mount rig for astrophotography/astroimaging.

A mounting cradle-ring clamps over optical tube assembly (OTA). The cradle-ring assembly 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 rack-and-pinion focuser helps make fine-focusing fast and precise. A 90° star diagonal is also included for more comfortable viewing. The mirror has dielectric coatings for a 99% light transmission for minimal light loss when using it.

Excellent Telescope

By Norman
Rated 5 out of 5

I bought this scope because it was highly recommended for astrophotography. I'm just getting started but I've been very pleased with it so far. The tube is small but solid. It's easy for one person to put on the mount. Early photos have been very good considering my experience level. Because of it's light weight balancing the scope on the mount is very easy. I wish they had a vixen mount for the finder scope rather than the Meade, but an adapter is easy to get online. All in all an excellent scope.

The first scope arrived damaged and was previously used as was evident by the indentations on the dovetail bar. I did not, however, receive the free Celestron Elements ThermoCharge Power Pack that was supposed to be included with purchase. The return/replacement was easy to set up with free fedex shipping. I also notified the service rep. that I did not receive the free product. The second scope arrived in good condition and the optics are terrific. Excellent scope and B & H also price matched the manufacturer's price drop. The new scope is excellent. B & H's service getting the replacement scope for the damage/used one was great also, but I never did receive the free Celestron Elements ThermoCharge Power Pack.

Great telescope for beginners

I am very satisfied with this scope. Great value! You can't find a triplet APO at a better value. It is important to note that this ideal for beginners learning astrophotography. There is some level of vignetting and field curvature but I'm using the Explore Scientific 2 field flattener and it solves the problem. My only issue with this scope was the short dovetail shoe. If you attach your camera train on the back, it is impossible to balance the scope on the mount. I attached a longer dovetail bar at the bottom of the shoe and that solved the problem. I was amazed at the images that I was able to capture with this scope given its price point. Highly recommended for beginners.

Highly recommended

A huge disappointment.

By Mahesh K.

I bought this scope for wide field astrophotography few months ago. But optical performance is way below I expected. I will list pros and cons as below- Pros- 1) Strudy built. 2) Triplet ED design so goo colours and almost no chromatic aberration. 3) Good quality 2 speed focuser and 2 inch diagonal. Cons- 1) Extreme field curvature and vignetting- This is the main disappointment with this scope. It is quite expected to have some field curvature at this much short focal length specially at this price, but this is too extreme. More than half of the distance from the edge to the center of the field is affected by field curvature so making most of the field of view is unusable. Even with field flattener/0.8 focal reducer from televue (TRF 2008) helps very little in flattening the field. This goes against my whole concept of using the scope for wide field astrophotography. 2) No finderscope. You have to buy it separately which is about the price of a pair of good binoculars. 3) Not coming with a carrying case as it's older model. 4) Short dovetail shoe. When balancing with camera and other imaging accessories attached, only one screw of the dovetail cradle of the mount can be used to hold the scope, as the scope has to be move way forward in the dovetail cradle.

question

What are the advantages of this versus a Canon 400mm f/5.6L?
Asked by: Arun H
Vignetting to start with, even at f5.6 your stars will defract with a camera lense. The scope aperture is not the same as lense aperture. For astrophotography the FCD version is really nice, very little vignetting and you can get away without running a gradient reducer in post. I liked it so much I also bought the 102 FCD CF. I'm using a hypertunned Celestron AVX and I'm able to get 10min subs with no streaking.

question

If you attach a DSLR camera on the telescope, what is the field of view?
Asked by: Anonymous
You can do a google image search of different objects imaged with an 80mm F6 and see exactly what it will look like. The scope is flawlessly built and definitely research grade as stated. I absolutly cherish mine!
