The large focuser can be rotated around the optical axis without changing the focus position. The standard MEF-3 Microfocus makes focusing easier with a 1: 7 reduction.

Since the FSQ only has a focus path of around 3 cm, an exact adjustment of the light path to the equipment to be connected is necessary. The back focus is 178 mm, so extension sleeves are ready. The following extension sleeves (we have specially provided screw-on extension sleeves to prevent the risk of tipping) and adapters are available on Tivoli and enable the connection of (almost) all conventional cameras for astrophotography:
- Extensions M72 to M72 thread: 2 x 52 mm
- 2 x 17 mm
- Adapter M72 to Wide-T
- Wide-T to Canon EOS adapter
- Wide-T to T2 adapter
- Adapter M72 to 2 "connection
The FSQ-106 ED is mounted on a 3" rail using original Takahashi pipe clamps and can be used on any mount you have brought with you, or on one of the TIVOLI mounts (with the exception of the ASA mounts).
