Hiyahs! Grinding the 10 inch beast goes on , but im making progress. Am starting to think about making a telescope to put it in eventually and saw an article in the latest Sky & Telescope about curved spiders. Looks simple to make and i get the theory about spreading the diffracted light around evenly. Up till now i have been thinking about doing a wire spider. Anyone got any comments on the relative advantages / disadvantages of each type??
