The FOA-60 from Takahashi is a new compact apochromatic fluorite doublet refractor. This telescope features a 60 mm aperture and a 530 mm focal length.
The spacing of the doublet elements is such that the correction of the spherical abberations is similar to that found in the much larger TOA series. This innovative design results in a Strehl ratio in excess of 96% for the base unit.
- Fluorite doublet apochromat
- Air-spaced doublet. Fluorite in the front
- Hard multicoatings
- 60 mm objective lens
- 530mm focal length
- f/8.8 focal ratio
- Dew shield OD: 80mm
- Optical tube OD: 68mm
- Length of optical tube: 500mm
- Weight: 1.5kg (3.30 lbs)
- Compact design for relatively long focal length, making it ideal for transport
- Outstanding visual and photographic performance, providing a 44 mm diameter image circle for full frame imaging
- Available with a 1.7x extender and a 0.93x flattener (each sold separately)
Note: Mount, tripod, tube holder and finder not included.
