Designed by PlaneWave's CTO David Rowe, the Delta Rho 350 f/3 is an innovative widefield telescope for unsurpassed deep sky astrophotography. With rock-solid fused silica mirrors, carbon fibre construction and an advanced baffled 60mm corrected image circle, the Delta Rho 350 is the capable of capturing the most stunning astrophotographs possible.

The Cassegrain focus f/3 astrograph has an aperture of 350mm (14") and has a focal length of 1050mm. Additionally, the Delta Rho 350 provides a huge 60mm corrected image circle so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos.

Being a fast imaging system, the Delta Rho has a fixed primary mirror, similar to the CDK series. In addition, the new PlaneWave-designed ultra-short derotator and focuser includes a tip/tilt adapter, making tilt adjustment very easy. 

Collimation is extremely straightforward, needing only simple adjustment of the three secondary mirror collimation screws. Multiple cooling fans on the telescope's backplate and sides of the optical tube allow the mirrors to quickly reach thermal equilibrium.



Note: The Delta Rho 350 requires extra crating (not included in the price) - this is roughly $550. Additionally, the Series-5 Rotator and Focuser are not included.

Features

  • Carbon fibre tube minimizes thermal expansion, which causes focus shift as temperature changes during an imaging session. Carbon fibre also reaches ambient temperatures quickly and is extremely lightweight and rigid to help ensure excellent imaging data is produced.
  • Dovetail Expansion Joint allows for the difference in thermal expansion between carbon fiber and aluminium. The expansion joint allows the aluminium dovetail to expand and contract without stressing the carbon fiber lower truss.
  • Cooling fans are strategically placed on the backplate and sides of the tube to quickly cool the mirrors to ambient temperature.
  • Advanced precision positioned, lightweight baffle tubes minimize vignetting and maximize image contrast. 
  • Compatible with the new Series 5 rotator and focuser (not included), which require only 70.6mm of space. This leaves 71.64mm of backfocus for further accessories. Both the Series 5 rotator and focuser require the Series 5 Controller (not included).

Note: The Delta Rho 350 is only compatible with the Series 5 Controller, not the previous Delta-T and EFA system. The Series 5 combines the functionality of both.

The Delta Rho 350 can be configured to use the PrimaLuceLab ESATTO 3.5" robotic microfocuser with the addition of our Testar-engineered adapter as show in the below images.
