Airy Disk APO 106mm f/6.6 Triplet ED FCD-100 Apochromatic Refractor
The 106mm Apochromat telescope is a dream come true for both astrophotography enthusiasts and visual observers who are seeking the utmost in contrast. With it’s slightly over 4-inch aperture, this telescope offers both portability and exceptional brightness.
The high quality triplet lens delivers a remarkably sharp image thanks to the utilizations of Hoya’s FCD100 ED glass, known for it’s minimal color aberration, crafted in Japan. This combination ensures the ability to capture razor-sharp planetary observations and produce breathtaking astrophotos.
The advantages at a glance:
Triplet apo lens with FCD-100 ED lens, designed around green as main color. Great color correction, well controlled in red and blue. Edge sharp. Field Flattener Correctors with adjustable backfocus up to 70mm. Amazing for visual observation, spot diagrams under images. Easily transformed into a super photo rig by unthreading the eyepiece holder(M63x1) and attaching the dedicated 0.75x or 0.92x FF.
Dedicated 0.75x Fieldflattener/Reducer for Fullframe
Larger than fullframe using our 0.92x FF
More about FCD100:
Thanks to technological innovation, Hoya has successfully optimized the mass production of FCD100. An optical glass with an extremely low dispersion, which even comes close to fluorite. By combining it with an optical glass with a high refractive index, it has been possible to achieve an unprecedented innovative chromatic aberration correction.
3.5" focuser for full-frame sensors
With this huge focuser, all your problems are a thing of the past - at least those that affect the illumination of your camera. Because you can use any camera from APS-C to full format and get perfect results thanks to the interaction of lens and focuser.
The focuser works on the basis of a hybrid technology consisting of rack and pinion (helical grooves) and ball bearings. This means: The focus can be set as soft as butter and precisely, but the load capacity and stability is high. Now you can even mount heavy cameras and equipment up to 10kg in weight.
M63 thread connection (internal): In addition to the classic 2-inch (with 1.25-inch reducing adapter) connection for eyepieces and cameras, this instrument also offers a 63mm thread so that you can easily and stably fix a flattener or reducer.
The handle with two uses
Simply clever: With the practical carrying handle, you always have your apo in your hand. Whether during transport or during assembly on the mount. In addition, the handle also serves as a mounting rail for accessories attached in parallel. So everything has its place: Use a guiding scope and guiding camera, for example.
