Our mobile telescopes

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

Have a total of three of these telescopes with varying dimensions. Starting at 8″ over 11″ up to 14″.

The C14 on the GM4000 QCI
Type Schmidt-Cassegrain
Manufacturer Celestron
Aperture 356 mm
Focal Length 3910 mm
f/Ratio 11
Spatial resolution 0.33″
Length of the tube 78 cm
Weight 20,4kg
Mirror coating StarBright™ XLT multicoating
Fastar compatible No

The C14 is our largest Schmidt Cassegrain telescope. It can be mounted on either the CGE-Pro or the CGX-L mount from Celestron. Before we got the CDK-20, the C14 used to be our main fixed telescope. The C14 cannot be used for solar observations. The setup and operation is basically equivalent to the C11. The setup of the CGX-L differs only in a few points from the CGE-Pro. However, the CGX-L is somewhat easier to handle than the CGE-Pro.

The C11 on the CGE Pro
Type Schmidt-Cassegrain
Manufacturer Celestron
Aperture 279.4 mm
Focal Length 2800 mm
f/Ratio 10
Spatial resolution 0.41″
Length of the tube 61 cm
Weight 12,5kg
Mirror coating StarBright™ XLT multicoating
Fastar compatible Yes

The C11 can be mounted on both Celestron's CGE-Pro and CGX-L mounts. We have a sun filter for the C11, so it can be used for solar observations. The setup and operation of the C11 and the CGE-Pro is described in a separate article. The setup of the CGX-L differs only in a few points from the CGE-Pro. However, the CGX-L is somewhat easier to handle than the CGE-Pro.

Type Schmidt-Cassegrain
Manufacturer Celestron
Aperture 203.2 mm
Focal Length 2032 mm
f/Ratio 10
Spatial resolution 0.57″
Length of the tube 43.2 cm
Weight 5.67kg
Mirror Coating StarBright™ XLT Multi-coating
Fastar compatible Yes

The C8 comes with the Advanced GT mount from Celestron. As for the C11, we also have a solar filter for the C8. The setup and operation of the C8 and the Advanced GT is described in a separate article.

Type Apochromat
Manufacturer TS-Optics
Aperture 130 mm
Focal Length 910 mm
f/Ratio 7
Lens type FPL53 triplet
Spatial resolution 0.89″
Weight 11kg

Our triplet apochromatic refractor offers a wide field of view. The scope is usually used with the CGX-L. The setup and operation is almost identical to the C11. The APO can also be used with the CGE-Pro.

The Solar Max II on the Advanced GT
Manufacturer Coronado
Series Solar Max II
Aperture 60mm
Focal length 400mm
f/Ratio 6.6
Bandwidth < 0.5
Blocking filter BF10
Other Richview tuning
:: Double Stacked
:: Sol Ranger Sunfinder

The OSST can be mounted on the Advanced-GT mount from Celestron. More details about the OSST, its setup and operation can be found in a separate article.
