In an attempt to reduce the flexure between my main scope and the guide scope, I have added a counterweight to the secondary mirror. The secondary mirror for the Meade LXD75 f/4 SN8 is rather large and hangs off the front corrector. I mounted a brass piece to the back of the secondary support and have a threaded shaft coming out of it with some small lead weights on the end. Fearing I might dump the threaded shaft and damage the corrector, I built a dew cap to protect it.
