PlaneWave Instruments PW20-RC, a 20 inch (0.51 m) telescope with Ritchey-Chrétien optics (f/6.8 RC optical tube, fused silica mirrors, focuser not included, Delta T ready). PlaneWave’s CDK astrographs have become the telescopes of choice for universities, industry, and astrophotographers around the world, and now PlaneWave offers the PW-RC series to meet the custom needs of the scientific community.

The PW20-RC in its native format (no field flattening lenses) uses only a primary and secondary mirror with reflective coatings. This can be useful when making observations primarily on-axis and wide field imaging is not a concern. The PW20-RC has a dual carbon-fibre truss design, with 3 cooling fans ejecting air from the back of the telescope. The instrument weight is 64 kg and comes standard with a back plate retaining ring ready to accept the focuser of your choice.

NOTE: Shipping cost will be determined after the order is made and must be paid for before the telescope will ship. A shipping quote can be obtained on request.
