Standard TS600 configuration with Riccardi 0.75 Reducer and CAA Rotator + rotating filter |
|||
all measures in mm
Main Features:
- BASIC configuration for TSO90/600 APO 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),
- M54 TS-Optics Filter Changer for 2" or 1.25" filters
- Advantages: The filter rotates with the camera. Therefore, any contamination of the filter can also be compensated for using flat calibration frames.
- Disadvantages:
- The camera tail is no longer universally compatible with other applications and requires more extensive modification for that purpose.
- The distance between the Riccardi reducer and the camera doesn‘t exactly
match the required value of 76.2mm, but the filter is rotating with the camera compared
to CID130. - Fixation of the camera tail to the telescope at the M48/M54 Rotator Changer
is a bit tricky with only 2 accessible screws !

Camera Tail Calculation
Table: TS600ASI2600x0.75CAAN
Calculated Focus points (based on 0.0029 mm/step)
- without 50mm tube extension:
- OLeN filter: ~ EAF step position 21250, focuser position= 61.82mm
- No Filter: ~ EAF step= 20972, focuser position=60.82mm
- Including 50mm tube extension (better weight balance!):
- OLeN filter: ~ EAF step position 3890, focuser position= 11.82mm
- No Filter: ~ EAF step= 3731, focuser position=10.82mm
Measured focuser position includes 2“ OLeN filter!
Rule: Add ~200 steps or 1.19mm for 2”filter!
