Easier for beginners, certainty for professionals! The completely redesigned and revolutionary collimator version 3.0 for your telescope. The market continues to develop towards short focal lengths and highly sensitive cameras with extremely small pixel sizes. This increases the requirements for a clean telescope alignment. The Ocal collimator is an innovative tool, which facilitates the adjustment in a completely new way. Each Ocal collimator has an internal motor that moves the CMOS chip linearly. Via the software, the focus can thus be ideally adjusted to the individual areas of the alignment. So you can focus on any area in the telescope without touching the setup or imagetrain. Colored centering circles can be selected and adjusted via the included software. The software also controls the line width of the circles as well as the contrast and exposure of the live image. Last but not least, a fade cross can be switched on and rotated via software. In this way, all areas that are important for the adjustment can be brought into focus and concentrically aligned very precisely. With the alignment of the crosshairs, the exact linear alignment of the trap can be assessed. Scope of delivery: OCAL 3.0 Connection cable 2x adapter Closing cap
