DeltaRho 350 Optical Tube Assembly

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 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!
