Svbony MK105 Modular Accessory System

This is a modular accessory system designed specifically for the Svbony MK105 Maksutov telescope.

The system is built around a base mount installed on the telescope tube, with interchangeable threaded accessories.

1 Base Mount (Core Component)

• No rubber bands, tape, or temporary solutions required

• Quick installation and removal

3 Solar Filter Holder

• Threaded attachment

The deep cylindrical seating helps prevent accidental detachment.

4 Protective Cap

• Threaded connection to the base

• Protects the front optics from dust and debris

• Secure fit without falling off

• Can remain installed when no other accessory is mounted

Designed for transport and storage protection.

⚠ IMPORTANT – Solar Observation Safety

Observing the Sun without a certified solar filter is extremely dangerous and can cause permanent eye damage.

• Never point the telescope at the Sun without a proper front-mounted solar filter

• Always inspect the filter material for damage before use

• Do not use if the filter is scratched, torn, or loose

• Ensure the filter holder is fully secured before solar observation
