Controlling Flexure Issues -

I added an additional 3-point ring to the TMB80/480 in order to steady/handle the extra weight of the CCD and/or reducer-flattener.  This is a 160mm ring that I had sitting around and will be replaced by more appropriately sized 90mm ring whenever the backorder gets here.  I replaced the Delron tips with a 1/4" fiberglass rod to make this quick-fix work. 

I have also updated my NP-127 with a 3rd ring support and now experience NO flexure.  I have even managed 30min exposures on my 10" LX200R while guiding with my NP-127 locked down in this manner (on a tandem bar).
