PlaneWave Instruments is pleased to offer the PW20-RC, a 24 inch (0.61 m) f/10.6 astrograph 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 PW24-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 PW24-RC has a dual carbon-fibre truss design, with 3 cooling fans ejecting air from the back of the telescope. The instrument weight is 108.9 kg and comes standard with a back plate retaining ring ready to accept the focuser of your choice. Delta-T Ready – Now the PW24-RC comes standard with built-in dew heaters for both primary and secondary mirror.

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.
