SVBONYExtension Tube M42x0.75 on Both Sides Length T2 Extension Tube Kit Length 5mm 10mm 15mm 20mm

Q: will this product fit the SV305 pro?

I'd contact SyBony directly - they make both the SV305 camera and this helicoid. The "1/25in" spec is common for telescope eyepiece accessories including cameras, but this version (they make others) of the helicoid has 42x0.75mm threads (T-mount) on both sides, implying another model or an additional adapter.

Q: what is the outside diameter?
