A non-focal reducing Field Flattener which gives improved results for photography with triplet and doublet refractor telescopes of between F5.5 and approximately F6.25 focal ratio.
The Lightwave 0.6x focal reducer gives an 0.6x reduction in F-Ratio for faster exposure times, as well as a correspondingly wider field for astro-photography. Designed primarily for refractor telescopes of F6 or longer focal ratios.
The ADC corrects for atmospheric dispersion (rainbow effect) producing sharper images of object closer to the horizon.
TAKAHASHI EXTENDER-CQ 1.7X (FS-60CB)
This field flattener/reducer screws directly into the rear focuser rotator of your refractor, converting it into an astrograph with a flatter photographic field than the existing lens system alone.
This field flattener is designed to work with the Altair Astro 80mm F6 Super ED Triplet APO, and has an M48 rear thread adapter for connecting your DSLR or CCD camera.
TAKAHASHI REDUCER CR 0.73X
CELESTRON .7X REDUCER C800HD
Being designed specifically for the TOA-130N and TOA-150B, RMS spot diameters of 1 micron on-axis are achieved.
The new FC/FS Multi-Flattener 1.04X is designed as a universal replacement to previous flatteners in the FS and FC series of fluorite doublet telescopes.
TAKAHASHI EXTENDER-ED 1.5X
The Takahashi Epsilon 1.5X extenders provide increased focal length without sacrificing optical performance.
