TSO600/90 APO configuration with Riccardi 0.75 Reducer and CAA Rotator and ASI 2600MC AIR + non rotating filter |
|||
all measures in mm
Main Features:
- BASIC configuration for TSO90/600 APO telescope with ZWO ASI2600 MC AIR camera
- Telescope: TSO 90/600 APO
- Camera: ZWO ASI2600 MC AIR
- Others components:
- ZWO CAA Rotator,
- TS-Optics M63 0.75 Riccardi Reducer / Flattner with 76,2 mm backfocus,
- M54/M48 rotation and change adapter (for a easy camera detachment),
- M45 TS-Optics Filter Changer for 2" or 1.25" filters
- Disadvantage: The filter does not rotate with the camera and must therefore be thoroughly cleaned before shooting flat calibration and light frames.
- Advantages:
- As the filter holder no longer rotates and the filter slot points 45° upward, the filter cannot accidentally fall off.
- The filter slider is more easily accessible even during operation.

Focus points:
- OLeN filter: ~ EAF step position 21250, focuser position= 61,82mm
- No Filter: ~ EAF step= 29000, focuser position=60,82mm
Important: When using filters, add 1/3 of the filter thickness in mm to the standard backfocus length!
e.g: Optolong I-eXtreme filter with 2mm thickness adds 0.67mm or 231 EAF steps to the backfocus.
