Skywatcher Telescope Esprit 150ED Triplet Apo Refractor 150 mm f/7 with Corrector
Skywatcher Telescope Esprit 150ED Triplet Apo Refractor Telescope 150 mm f/7 with Corrector核心参数
The new 3-elements apo refractor telescope offers maximum sharpness on the axis. The Triplet FPL53 Super ED objective produces a very sharp image free of colour aberations. The APO has a doublet field flattener to get a flat field - full 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 included flattener all adapters are included 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.
Our new Riccardi Reducer are now available for this Apochromat too. Tests shows the high quality from the reducer with this telescope too.
