PlaneWave DeltaRho 350 Telescope

Starting Price: $18,500.00
Price as Configured: $18,500.00
Brand: PlaneWave Instruments / SKU: PW-140126Q

PlaneWave’s revolutionary Delta Rho 350 f/3 telescope is designed for unsurpassed wide field imaging and ease of use. Since the primary mirror is fixed in place, collimation is quickly achieved by adjusted the tip and tilt of the secondary mirror. With the Delta Rho 350, your astrophotography experience will be second to none.

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.

Standard Features

Corrected Cassegrain The corrected design yields a flat field free from off-axis astigmatism, coma, and field curvature.
Carbon Fiber Truss Design Minimizes thermal expansion which causes focus shift with changes in temperature.
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 cooling fans blow air inside the back of the telescope. This helps the telescope to reach thermal equilibrium quickly. The fans are controlled by a computer if the optional Electronic Focus Accessory (EFA Kit) is purchased.
Delta-T Ready For added dew prevention, the DR350 is internally wired with polyimide film heater pads and temperature sensor, ready to be controlled with the optional Delta-T controller.
