Our mobile telescopes

Besides our fixed main telescope, the CDK20 from Planewave, our telescope family currently includes the following telescopes:

We have a total of three of these telescopes in different sizes ranging from 8″ to 11″ and up to 14″.

The C14 on the GM4000 QCI

Compatible mounts CGE-PRO, CGX-L, EQ8-R PRO

The C14 is our largest Schmidt-Cassegrain telescope. Before the CDK-20, the C14 was our primary fixed telescope. The C14 cannot be used for solar observations.

In our family of telescopes, this is the fastest telescope with the largest field of view and is therefore most commonly used for wide field observations. The Baader UFC (Universal Filter Changer) is available for this telescope with narrow band high speed filters as well as a complete set of SOLAN/SDSS filters.

Compatible mounts CGE-PRO, CGX-L, EQ8-R PRO

Our apochromatic refractor offers a large field of view. For this telescope we have both a solar filter and a Herschel prism for solar observations.

The Solar Max II on the Advanced GT
Manufacturer Coronado
Series Solar Max II
Aperture 60mm
Focal length 400mm
f/Ratio 6.6
