Product Details

  • The Starfield ED102 APO doublet offers incredible performance in both imaging visual astronomy. Using FPL53 (Ohara, Japan) and a lanthanum element, chromatic correction rivals more expensive triplet telescopes with the advantage of faster cool down time. Taken to the highest magnification, images and views remain colour free. This fast refractor for lunar and solar system observation and demanding astrophotography applications.

    High-Quality Build and Features

    • 2.5" two-speed rack and pinion focuser, with ball bearings, that is also fully rotatable rotation. Optional Motor focusers can easily be installed. Self-centering rotational lock. No setscrews to come loose. Support for heavy camera loads and accessories.
    • Supports 2" and 1.25" eyepiece accessories
    • HD CNC tube rings and Vixen-style dovetail bar
    • Retractable dew shield retractable for transport. With the dew shield retracted the total length is 24”

    Doublet Apo 102 mm f/7 - FPL53 / Lanthanum Objective

    • Aperture 102 mm / focal length 714 mm / focal ratio f/7
    • Adjustable doublet in temperature compensated cell
    • Image free of chromatic error due to "Extra-Low-Dispersion" FPL53 apo element from Ohara (Japan) and Lanthanum element. Achieving better chromatic correction than comparable apochromats with doublet lenses with lower quality glass.
    • Shorter cooling time than with triplet lenses, thus quicker operation possible
    • Internally baffled to prevent stray light and get the contrast you would expect from performance refractors.
    • 2.5" two-speed rack and pinion focuser that is also fully rotatable rotation. Optional Motor focusers can easily be installed. Self-centering rotational lock. No setscrews to come loose. Support for heavy camera loads and accessories.
