Vai al moduloSelf-centering 2" laser collimator with Crosshair beam for precision collimation of Newtonian and Schmidt-Cassegrain telescopes — Hotech's SCA technology eliminates the off-axis problem at its root
The problem all other collimators ignore
The focuser clamp screw pushes any standard collimator off the optical axis on one side. The Hotech SCA-2C solves this with SCA technology: an internal rubber membrane expands uniformly when the locking ring is turned, centering the collimator precisely on the 2" focuser axis.
Crosshair model: crosshair for primary and secondary mirrors
The Crosshair model adds 4 reference lines for more precise centering of both mirrors — especially when the telescope is severely decollimated. The 45° target plate with laser-etched grid is included as standard.
Professional quality construction
CNC-machined body, minimal weight, included CR123 3V lithium battery. Delivered in an elegant hard case.
