The focuser is attached to every telescope near the focal point of the light-gathering optics. As the name suggests, eyepieces can be inserted into the focuser. For astrophotography, focusers hold cameras and bring them into focus. This is why they are also referred to as focusers instead of eyepiece focusers.
The UltraLight focuser is suitable for these telescope types: SC, RC (only with M90 x 1 connection), Skywatcher brand Newtonians.
Our expert comment:
To connect the Artesky UltraLight V3 focuser to an RC telescope, the appropriate adaptor (item 74230) is also required.
