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″ |

| 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 |

| Useable field | 52 mm |
| Weight | 19,5kg |
| Mirror coating | StarBright™ XLT multicoating |
| Compatible mounts | CGE-PRO, CGX-L, EQ8-R PRO |
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.
Refracting telescopes
130mm Apochromat from Teleskop-Service
