Airy Disk APO 96mm f/6 Triplet ED FCD-100 Apochromatic Refractor APO
A compact apochromat for powerful images This APO with a 96mm aperture offers
This APO with a 96mm aperture offers astrophotographers and visual observers excellent optics and high-quality mechanics. An almost 4-inch aperture with good resolution makes it wonderful for both astrophotographers and visual observers alike. Thanks to the high-quality triplet lens system, this telescope is one of the best of its kind. One reason for this is the Hoya ED glass FCD100 made in Japan with its exceptionally low dispersion. Discover the charm of the sky with it!
The advantages at a glance:
- Triplet apo lens with FCD-100 ED lens: High-quality apochromatic lens with pure color and high-contrast imaging
- Inner screens against reflections for even better contrast in observation and astrophotography
- 2.5 inch hybrid focuser with 1:10 reduction: Connect even heavy accessories up to 10 kg
- Carrying handle and rail in one: Practical for transport and for mounting additional accessories such as a guiding scope
- Everything has been thought of: This telescope comes with CNC tube rings, GP mounting rail, finder shoe and extendable dew cap. A telescope for astrophotographers to get started!
Made for perfect astro photos
The apochromat has arrived in modern times, because the imaging of this telescope is nothing short of excellent. Thanks to the ED Triplet Apo lens with air gap, it relies on a particularly high-contrast and color-free image. At the center of your astrophoto machine is the FCD-100 glass from Hoya of Japan, which is known for its low color deviation. Treat nebulae and planets to a very high magnification: the images remain clear and sharp even then.
A telescope for all astro enthusiasts who value a high-quality image.
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.
Large 2.5" focuser: Precise and stable
The improved 2.5 inch hybrid focuser makes observation and photography even more convenient and precise. This focuser is based on the Crayford principle, but with an additional guide rail in the form of a toothed rack with helical grooves. The combination of these techniques makes the focuser particularly precise and yet stable.
Easily connect whatever you want, from adapters to large eyepieces or heavy camera gear: it can carry gear weighing up to 10kg. Once the focus is set, it stays in place with every movement of the telescope.
360 degrees rotatable: With the rotatable and lockable focuser, alignment with the photo object is very easy.
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.
