Capturing the most stunning astrophotographs possible is something PlaneWave is passionate about. From design to manufacture, our goal with the DeltaRho 350 was centered around creating a game changing wide field telescope. The DeltaRho 350 is a Cassegrain optical design which means the imaging train is secured at the back of the telescope and does not block the light path compared to prime focus designs, which severely limit users ability to operate with filterwheels, or large cameras.

The DeltaRho 350 is an incredible breakthrough in telescope technology and ease of use. Operating at f/3 and 1050 mm focal length, the DeltaRho is a wide field telescope that is sure to revolutionize your astrophotography!

Additionally, the DeltaRho 350 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the DeltaRho 350 is an exceptional diffraction-limited telescope. DeltaRho 350 users can experience pinpoint stars edge-to-edge and a 170 x 170 arcminute field of view when using large 16803/4040 size camera sensors. This field of view is nearly 3 times as large as our CDK14! When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!

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.
