The DF66 Astronomical Telescope System is a photo-visual telescope that combines a high-performance astronomical telescope featuring a 66mm effective aperture doublet fluorite apochromatic objective lens with a high-performance corrector lens based on advanced optical design.
This combination achieves both high-quality visual and photographic performance.

Self-Introduction

Hello, I am Tetsuya Abe, Representative of Abe Precision Optics LLC.

From 1987, I worked for 21 years at PENTAX Corporation (formerly Asahi Optical Co., Ltd.) engaged in optical design. In 2008, I became independent and established Abe Optical Laboratory, where I have continued to dedicate myself to optical design.

Leveraging technologies honed at optical manufacturers, such as diffraction-limited optics and super-apochromatic design, I handle optical design for diverse equipment including semiconductor lithography and inspection systems, medical devices, digital cameras, projectors, and telescopes/binoculars.
In the astronomical telescope field, I was responsible for the PENTAX SDP series, XL/XW eyepiece series, and BORG FL series telescopes, all of which have received high acclaim.

Furthermore, I am an avid astronomy enthusiast who loves both visual and photograph of stars, a passion that began when I first saw Jupiter through a school telescope in fifth grade.
That said, I remain an amateur at both visual and photograph. However, from the dual perspectives of both an astronomy fan and an optical designer, I constantly ponder what kind of optical system would be optimal for visual and photograph celestial objects like these.

What I Aim to Achieve with This Project

While many manufacturers release 6cm-class astronomical telescopes, I feel few products achieve a high level of performance in both visual and photograph.

The DF66 system boasts high visual performance thanks to its doublet apochromatic objective lens using fluorite crystal lens.

Additionally, when combined with dedicated corrector lenses, it delivers high performance astrograph and also provides a wide image circle with 645 digital cameras.

While it can't compete on price with other manufacturers' products, the DF66 system's high performance should satisfy even veteran astronomy enthusiasts.
Its compact tube is also ideal for mobile observing and overseas expeditions.
For beginner astronomy fans, the price may be a significant hurdle, but once getting hands on it, it should be able to use it for many years to come.

I hope many astronomy fans will experience the DF66 system.
