PlaneWave RC20 Telescope
Price as Configured: $57,500.00
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.

Ritchey-Chrétien (RC) Optics
Fused silica RC optics made by PlaneWave for excellent on-axis performance using only a hyperbolic primary and secondary mirror with no refractive optics in the light path.
Carbon Fiber Truss Design
Minimizes thermal expansion to prevent focus shift with changes in temperature.
Dovetail expansion joint
Accommodates the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminum dovetail to expand and contract without stressing the carbon fiber lower truss.
