  The SVBONY Helical Focuser allows for precise focusing of eyepieces or cameras, making it ideal for achieving sharp, clear images during both planetary and deep-sky astrophotography.

• Perfect for Guide Scopes and Cameras

  This focuser is specially designed for use with guide scopes like the SV165 mini guide scope, ensuring accurate focus for guiding and imaging with both eyepieces and cameras.

• Dual T2 Thread Compatibility

  The female T2-thread on the telescope side and male T2 thread on the camera side provide versatile compatibility for attaching various accessories, including 1.25" equipment, without the need for additional adapters.

• Fixed Orientation During Focusing

  The SVBONY Helical Focuser keeps attached accessories in a fixed orientation during focusing, ensuring that your eyepiece or camera stays steady and doesn’t rotate, making your setup more stable and easier to adjust.

  Once you achieve the desired focus, the clamp screw locks the position in place, ensuring your focus remains fixed for long exposures or tracking without needing readjustments.
