Explore Scientific ED80 Triplet Essential Series Imaging Package - Not Available

The Explore Scientific ED80 Triplet Imaging Package comes complete with the 80mm APO telescope, dedicated field flattener for CCD/CMOS astrophotography, and a hard carry case. This is a true three-element apochromatic telescope capable of producing research-level image quality.

DSLR USERS, PLEASE NOTE the included field flattener will NOT work with your DSLR and standard T-Ring, as the back focus is 45mm. If you use a Canon or Nikon DSLR, you will need to purchase one of the follows field flatteners separately:

Field Flattener for Nikon users: ES-FFEDAPO-NI

Field Flattener for Canon users: ES-FFEDAPO-CA

Fine optical quality, deluxe 2-speed focuser, and 99% dielectric 2" diagonal make this telescope an extreme value!

Explore Scientific 80mm f/6 Essential Series Triplet Refractor Features...
  • The Explore ED80 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 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 heavy-duty 2" dual-speed focusers.
  • The included 2" diagonal has a precision-polished mirror with enhanced 99% dielectric coatings.
  • 2" Explore Scientific Field Flatter ES-FFEDAPO-00 included
  • To attach your Explore Scientific Air-Spaced Triplet telescope to a variety of mounts, we have included the "Vixen-style" dovetail. The "Vixen-style" plate fits mounts made by Explore, Meade, Celestron, Vixen & others.

Nice scope but field flattner is defective.

Received this package a couple of months ago. Very nice scope and case with accessories. The problem is the field flattner was defective. The bezel that goes around the top was missing. Basically this allows the flattner to fall straight thru the focuser into the OTA assembly. Tried contacting OPT several times with no response. Contacted ES customer service and received an immediate response and an RMA to send it to them. Received it back and it's still not fixed. Attempted contact with ES have gone unanswered from that point on. So basically I have a field flattner that does me no good so I'll most likely replace it with another vendors version. Would have highly recommended this if it was handled to a better degree. As it stands now I'm pretty much done with OPT. This was their second chance that I've given them. Seems under the new ownership they have been lacking at best and incompetent at worst. ES is now on my never again list also.

Great Scope and accessories for imaging

I recieved the telescope with all accessories as promised promptly. The telescope is well built and came with the accessories necessary for viewing and imaging with a short tube, i. e. two extenders, a flattener and a very nice diagonal. The case is very nice and substantial with plenty of extra room for extra accessories. I wish all telescope manufacturers and vendors would provide at least some accessories necessary to address back focus issues with their telescopes. I have purchased 5 telescopes over the past few years as I tackled the huge learning curve with astrophotography, and have always had to figure out what is needed to get the scope in focus with my ccd and DSLR , then hunt down and order extenders, flatteners/focal refucers etc. This scope came with everything I need! I have only used the scope once for imaging so far ... took photos of the recent total lunar eclipse. Great quality images!
