Airy Disk APO 140mm f/6.5 Triplet ED FCD-100 Apochromatic Refractor
Large opening for the small home observatory
The Omegon 140mm Apochromat is a telescope for astrophotographers and visual observers looking for the highest image quality and a large instrument. Thanks to the size of the optics, it collects a lot of light and is ideal for small observatories or amateur astronomers with a fixed location. If you are not afraid of some larger equipment, then this telescope can also give you wonderful astro photos in less light-polluted areas. The higher resolution also makes this telescope an expert for close double stars. Visual deep-sky observations with high contrast also work particularly well with the 140 f/6.5. The triplet lens is particularly sharp and uses the high-quality FCD100 ED glass manufactured by Hoya in Japan with extremely low color deviation, which enables pin-sharp planetary observations and impressive astro photos.
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
- 3.5 inch hybrid focuser with 1:10 reduction: Connect even heavy accessories up to 10 kg
- 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.
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 reduction 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.
