[ATM] Wire Spiders
Dear ATMers:
I am putting together a 10" f/7.2 Newtonian from my own mirror and a 1/25
wave fused quartz diagonal. I am planning to use a PLOP type mirror support
cell.
I would like to try to use wire spiders to hold the secondary. Any advice on
type and thickness of wire, angles of geometry and tensioning devices? I'm
using a 12" aluminum main tube from Hastings Irrigation.
