PlaneWave Instruments is pleased to offer the RC24, a 24 inch (610mm) 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 RC series to meet the custom needs of the scientific community. The RC24 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.
Ritchey-Chrétien (RC) Optics: 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. (An optional field correcting lens group can be added to improve off-axis performance.)
Carbon Fiber Truss Design: open truss tube design with carbon fiber frame minimizes thermal expansion which causes focus shift with changes in temperature. Carbon fiber truss design also promotes quick thermal cooling and provides a rigid, lightweight structure.
Dovetail expansion joint: allows for the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminum dovetail expand and contract without stressing the carbon fiber lower truss
Cooling Fans: three fans blow out of the optical tube pulling air though the telescope and by the primary mirror. This helps the telescope to reach thermal equilibrium quickly. The fans are controlled by a switch on the optical tube or can be controlled by a computer if the optional Electronic Focus Accessory (EFA Kit) is purchased.
