Why choose the SV239?
- Dual-sided mounting: Vixen/Synta and Arca-Swiss profiles offer greater flexibility between compatible mounts and clamps.
- More room for balancing: the 185mm rail and elongated slots support adjustment of mounting position.
- Lightweight construction: anodised aluminium combines low weight with a hard-wearing finish.
- Flexible mounting holes: UNC 1/4-20 and UNC 3/8-16 interfaces accommodate compatible equipment and fasteners.
Check your setup before ordering
This is a dovetail mounting plate, not a clamp. Confirm your mount or saddle accepts the intended Vixen/Synta or Arca-Swiss profile. Also check the spacing, threading and dimensions of the mounting points on your telescope rings, camera or accessories. Other equipment pictured for illustration, if any, is not included.
