Askar FRA500 90mm f/5.6 Refractor
US$ 2,096.29The best seller of the quintuplet series, the FRA500 90mm; It is an instrument suitable for astrophotography.
Thanks to the quintuplet spaced in the air, it provides a flattened field up to 44mm diagonally without the addition of further flatteners/reducers.
- Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
- Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.
- NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
- Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
- Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
- CGE dovetail mounting rail.
- Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.
