ED102 f/7 714mm APO

The Starfield ED102 APO doublet offers incredible performance in both imaging an 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.

This 714mm f/7 offers high performance that you would typically see in higher priced triplet telescopes.

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 dew shield retracted the total length is 26”

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.
Supports 2" and 1.25" eyepiece accessories
