Add to Wish List Compare this ProductThe new 3-elements apo refractor offers maximum sharpness on the axis. The Triplet FPL53 Super ED objective produces a very sharp image free of colour aberrations. You can optionally get a doublet field flattener to get a flat field - fully corrected - for astrophotography. The flattener offers a generous back focus allowing the use of filter wheels or off-axis-guiders. The focuser offers 1:11 microfocusing and 360° rotation for perfect framing.
For photography with the flattener we can offer you all adapters are up to the Canon EOS adapter. For the using of accessories like an off axis guider or different cameras we can make you a special offer.
