I’ve built an aluminum plate for my equatorial mount to allow it to carry the main telescope and the guide scope for autoguiding purposes. In autoguiding, it is important to minimize flexing between the imaging telescope and the guide scope, thus, a plate with suitable thickness helps address this problem. This DIY plate measures 12 cm by 20 cm by 1 cm and made from a solid aluminum plate from a local metals supply shop. Holes have been drilled on the plate to allow attachment of various loads such as DSLR cameras and different telescopes.
