PlaneWave 20 Inch RC Optical Tube
The PlaneWave Instruments PW20-RC is a 20-inch (0.51 m) f/6.8 Ritchey-Chrétien (RC) Astrograph telescope. The PW20-RC has a dual carbon-fiber truss design, with 3 cooling fans ejecting air from the back of the telescope. The instrument weight is 140 lbs (64 kg) and comes standard with a back plate retaining ring ready to accept the focuser of your choice.
PlaneWave Instruments is pleased to offer the PW20-RC, a 20 inch (0.51 m) telescope with Ritchey-Chrétien optics. 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.
