Explore Scientific ED102 102mm f/7 FCD100 Triplet Telescope in Carbon FiberHauling an aluminum refractor tube to a dark site or up to a rooftop observatory adds weight that compounds with the mount, tripod, and accessories. The Explore Scientific ED102 FCD100 Carbon Fiber delivers apochromatic triplet performance with HOYA FCD100 glass in a carbon fiber tube that sheds weight, resists temperature driven focus shifts, and looks the part at a fraction of what comparable 4 inch carbon fiber APOs cost from competitors.

Hauling an aluminum refractor tube to a dark site or up to a rooftop observatory adds weight that compounds with the mount, tripod, and accessories. The Explore Scientific ED102 FCD100 Carbon Fiber delivers apochromatic triplet performance with HOYA FCD100 glass in a carbon fiber tube that sheds weight, resists temperature-driven focus shifts, and looks the part — at a fraction of what comparable 4-inch carbon fiber APOs cost from competitors.


Key Features
  • HOYA FCD100 Extra-Low Dispersion Glass – FPL-53 equivalent optics virtually eliminate false color, delivering sharp, true-to-life views of planets, double stars, and deep-sky targets in both visual and imaging use
  • Air-Spaced Triplet Optical Design – Three-element configuration achieves 1.14 arcsecond resolution and diffraction-limited performance with high contrast across the field
  • Carbon Fiber Tube Construction – Significantly lighter than aluminum alternatives and far more thermally stable, reducing focus shift during long-exposure imaging sessions and speeding up cool-down time at the observing site
  • 2.5" Hexagonal Dual-Speed Focuser – Rock-solid rack-and-pinion design with 10:1 fine focus ratio supports up to 10 lbs of imaging gear with zero flex or image shift
  • EMD Enhanced Multi-Layer Coatings – Proprietary broadband coatings maximize light transmission and contrast for faint deep-sky targets
  • Versatile f/7 Focal Ratio – Long enough for high-magnification lunar and planetary detail, yet pairs well with a field flattener for sharp, flat-field deep-sky imaging
  • Retractable Carbon Fiber Dew Shield – Blocks stray light and slows dew formation during extended sessions without adding bulk
  • 99% Reflective 2" Diagonal Included – Premium dielectric diagonal maximizes light throughput right out of the box, so you can start observing without additional purchases

Ideal For
  • Astrophotographers on mid-range mounts who want sharp, well-corrected optics that perform on a HEQ5, Celestron AVX, or similar payload — the 9.5 lb carbon fiber OTA leaves plenty of weight budget for cameras and guide scopes
  • Visual observers stepping up from doublets looking for clean, color-free views of planetary detail, tight double stars, and crisp star clusters without the chromatic aberration that plagues two-element designs
  • Grab-and-go astronomers who want serious apochromatic performance in a compact, lightweight package that sets up quickly and reaches thermal equilibrium fast
  • Budget-conscious buyers who want genuine FCD100/FPL-53 triplet APO quality without paying the $2,500–$3,000 that competing 4-inch triplets demand — this scope delivers the optical performance at roughly half the price

Accessories & Compatibility

Note: A finder scope and carrying case are not included. The pre-installed 2N1 finder scope base accepts most standard finder scopes and guiding systems.

Poor quality control - maybe outlet store leftovers
Size: 11.5, Color: Burgundy Polished Full Grain
The two shoes were not the same size. They were both labeled 11 1/2 but one shoe was larger than the other and the fit was poor. I returned the first pair and ordered a replacement. This time the shoes were close to the same size but too loose and the left one has sewing issues. I've bought Johnston & Murphy for years because of the quality. These were to replace an existing pair of burgundy penny loafers that have finally worn out (even after several heal/sole replacements). That is the expected quality. I suspect Nashville Shoe Warehouse may be handling shoes that didn't measure up for the quality; more like an outlet mall than getting the J&M quality I've come to expect. Update: went to Johnston & Murphy site to buy "direct" from the manufacturer. There were several recent reviews where the shoes were long and didn't fit properly. Genesco - please step up the manufacture / crafting of these classic shoes to the level of quality they used to have.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.
