A micro focuser is a reduction gear that allows for sensitive focusing. Many focusers already have such a reduction gear or can be retrofitted with one.
Microfocusing is very convenient for visual observation and absolutely essential for astrophotography.
The Tecnosky Fast-Reverse micro focuser is compatible with most Tecnosky refractors that have a rack and pinion focuser. Unlike other motor focus units, which are often connected to the rotation axis of the focuser, the Tecnosky Fast-Reverse is mounted directly on the axis of the focuser, generating a high torque that is capable of moving cameras and accessories weighing up to 5 kg.
The great feature, however, is that you can disconnect the motor focuser from the axis of the focuser with a simple twist, leaving manual focusing free. Switching from electronic to manual mode is quick and safe, and there is no longer any need for an inconvenient and often expensive hand controller!
The Fast Reverse motorisation is connected to the PC via a USB or Bluetooth cable and controlled via the ASCOM software: Here, the use of a high-quality gearbox results in a very precise and repeatable "V-curve" during autofocusing. A smartphone app will also be available soon, allowing the motorisation to be controlled via mobile phone. Optional adaptors are available so that the Fast-Reverse can also be mounted on most commercially available focusers.
Only the motorisation unit is supplied – the respective flange or connecting bracket must be purchased separately depending on the focuser used.
Features:
- High-torque motorisation
- Option of manual operation of the focuser
- USB and Bluetooth connection
- ASCOM compatible
- Can also be used with smartphones
- 12V power supply
