Our mobile telescopes
Besides our fixed main telescope, the CDK20 from Planewave, our telescope family currently includes the following telescopes:
Schmidt Cassegrain telescopes from Celestron
We have a total of three of these telescopes in different sizes ranging from 8″ to 11″ and up to 14″.
C14
| 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 |
| 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.
C11
| 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 |
| Compatible mounts | CGE-PRO, CGX-L, EQ8-R PRO |
We have a solar filter for the C11 so it can be used for solar observations.
C8
| 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 |
| Compatible mounts | Advanced GT |
As for the C11, we also have a solar filter for the C8.
Refracting telescopes
130mm Apochromat from Teleskop-Service
| Type | Apochromat |
|---|---|
| Manufacturer | TS-Optics |
| Aperture | 130 mm |

| Lens type | FPL53 triplet |
| Spatial resolution | 0.89″ |
| Weight | 11kg |
| 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.
