    Top notch Triplet Refractor

    After reading online about the ED FPL-53 triplet Scopes from ES, I knew I had to get one. It was just a question about what kind’ve aperture I wanted for my needs. After speaking with customer support at RCT, they recommended the ED140. I had previously had some experience with a 100mm Refractor, but I wanted to ensure that I didn’t spare any expense on Aperture this time around. Excellent choice!
