Guide for SV705C Connecting with 2inch Field Flattener

• All-in-1 video and audio conferencing solution;
• Full HD Video and Audio;
• Great & Smooth Conference Experience;
• Easy Setup video conferencing;
• Ultra Compatibility.

• 102mm large aperture; large objective lens refractor telescope; high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter;
• f/6.5 short focal ratio; larger field of view; can collect more light; the image is brighter; and the observation target is clearer and easier to observe;
• Dual-speed focusing; fast focus allows you to quickly move the focus wheel to roughly focus on your target; while slow focus adjusts focus more finely for optimal image clarity;
• Integral telescope rings; the tube rings make the telescope more stable and avoid wobbling; and provide a stable support to keep the optical components of the telescope stable relative to each other;
• Easy to assemble and use; the telescope is designed to be user-friendly; it can be set up quickly without additional tools; you can find a lot of fun in assembling.

Note: The main lens have been corrected completely.
