SVBONY Reflectors FCAW9140A Editorial Review
The SVBONY SV181 Rack and Pinion Focuser is a 1.25 inch Newtonian Reflector Focuser suitable for use with a homemade dob. It features all-metal hardened steel Construction, an oversize drawtube, silver steel knobs, a brass eyepiece locking system, and a spring tension mechanism. However, reviews report it may have a bit of play when focusing, and the tension mechanism can be difficult to adjust precisely. The focuser appears to be well-built, sturdy and reliable, however, there are reports that it is not any better than the plastic stock focuser that comes with a budget scope without mounting screws.
