Introducing PlaneWave’s revolutionary Delta Rho 350 f/3 telescope. The Delta Rho 350 is designed for unsurpassed wide field imaging and ease of use in the field. 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!

Corrected Cassegrain focus optical design
Aperture – 350 mm
Focal length – 1050 mm
Focal Ratio – f/3
60mm Image Circle > 3 degrees
Fixed Primary Mirror and Secondary Mirror
Backfocus – 5.6” (142.24 mm) from mounting surface
Built in primary and secondary dew heaters with temperature sensors
*L-350 mount seen in product photo is sold separately

Description

Capturing the most stunning astrophotographs possible is something our team 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 produces no off-axis coma and no off-axis astigmatism. 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.
