I rebuilt my 12 inch f/6.1 mirror into a lightweight Dobsonian. Total weight is about 16 kilo's. I made a wire spider for it and an aluminium 6-point mirror...

Sorry, I don't know if they are available in Europe or not. But in North America, ArmorAll Protectant (the band name) works great. Also, any car wax with...
Experiment carefully with these things. Wax can greatly reduce friction, and your telescope may then not stay properly pointed. For example, you might try...
I've used silicone spray before. It seems to have some sort of solvent in it, and as it eventually dries (that will take some time), it gets sticky. -John...
