With these risers, you raise your entire telescope by 65mm above the dovetail bar, which allows full rotation of the focuser and allows the telescope to balance properly. Risers also prevent off-axis guiders and filter wheels from pressing against the ground when the telescope is not in use.
The attachment kit enables the ZW-Optical EAF motorised focusing system to be connected and makes focusing child's play. The EAF system enables focussing via the computer with temperature compensation.
The Bahtinov mask is named after the inventor Pavel Bahtinov. This focussing aid enables clear focusing of astro images in the focus of your telescope or with a camera lens.
Place the mask on the telescope and point it at a bright star.
Switch on the camera and observe the constellation on Live View or on the computer.
f the image is not exactly sharp, the centre line is shifted. Adjust the focuser until the central line runs exactly through the centre of the star.
You have now achieved optimum sharpness. Remove the mask from the telescope again and you can start exposing the image.
