When we install many instruments (for example telescope with guide scope in parallel) on the mount, it can happen that they are too close together, and that some element touches the others. That's why we created the PLUS 10mm spacers that can be fixed between two mechanical elements (such as a plate and the support rings), keeping the functionality of the...
