Following the successful introduction of the DeltaRho 350, the DeltaRho 500 is now available to make large field photography even easier. With a fixed primary mirror, the system can be quickly collimated by simply adjusting the secondary mirror. With more than twice the light gathering power of the DeltaRho 350, it has never been easier to get the most out of an astrograph.
From development to production, PlaneWave Instruments' goal was to create a revolutionary large-field telescope with the DeltaRho 500. The DeltaRho 500 is a Cassegrain telescope with the imaging train located at the rear of the telescope, so that even large filter wheels and cameras do not obstruct the light path. This is a real advantage over instruments where the camera and accessories are located in front of the primary mirror in the prime focus, which can severely limit the user's options. The DeltaRho 500 operates at f/3 and 1537 mm focal length, taking you to the next level of astrophotography with large sensors without the limitations of instruments that use the prime focus.
Last but not least, the DeltaRho 500 offers a perfectly flat image field that ensures breathtaking sharpness from corner to corner without any deterioration due to image field curvature. Thanks to decades of experience in telescope construction, the DeltaRho 500 offers easy collimation with just one mirror, as well as stray light suppression through advanced 3D-printed baffles and a torsion-resistant construction developed using finite element analysis (FEA). DeltaRho 500 users can enjoy pin-sharp stars from edge to edge and a 2-degree field of view when using large 16803/4040 (52 mm) camera sensors. This field of view is more than twice as large as that of the CDK 20!
The quartz glass (fused silica) used is a synthetic amorphous quartz glass of the highest purity and one of the most transparent glasses available. Due to its purity, the optical and thermal properties of quartz glass are superior to other types of glass. Its transmission and homogeneity exceed those of crystalline quartz and avoid the problems of temperature instability that crystalline quartz glasses suffer from.
Fused silica has a thermal expansion coefficient six times lower than that of borosilicate glass (Pyrex). It therefore retains its shape with a very high degree of accuracy when it cools. This results in consistent optical performance and an unchanged focal point during temperature changes.
Included in delivery:
