NEW: PlaneWave DeltaRho 500 f/3 Teleskop

After successfully introducing the DeltaRho 350, the DeltaRho 500 is now available for transcending the challenges of-ultra wide field imaging. With a primary mirror that is fixed in place, collimation is quickly achieved with a simple adjustment to the tip and tilt of the secondary mirror. With more than twice the light-gathering power of the DeltaRho 350, maximizing the performance of your astrograph has never been easier.

From design to manufacture, PlaneWave Instruments goal, with the DeltaRho 500 was centered around creating a revolutionary wide-field telescope. The DeltaRho 500 is a Cassegrain Optical Design with the imaging train at the back of the telescope to prevent obstruction of the instrument. This offers a real advantage against prime focus designs, which can severely limit users’ ability to operate with filter wheels or large cameras. The DeltaRho 500 operates at f/3 and 1537 mm focal length, which brings the next level of astrophotography with large sensors and without the limitations of prime focus devices.

Last, but not least, the DeltaRho 500 provides a perfectly flat field, which ensures stunning clarity from corner-to-corner images without field curvature degradation. With decades of telescope design experience, the DeltaRho 500 offers the simplicity of single-mirror collimation, stray light control of advanced 3D printed baffles, and structural performance created through finite element analysis (FEA). DeltaRho 500 users can experience pinpoint stars edge-to-edge and a 2-degree field of view when using large 16803/4040 (52mm) size camera sensors. This field of view is over twice as large as our CDK 20!
