The June meeting of the Longmont Astronomical Society will by on Thursday, June 16th at the IHop Resturaunt, 2040 Ken Pratt Blvd., Longmont, CO. A group of us will meet for dinner around 6 pm at the resturaunt, you are welcome to join us! The general meeting will begin at 7 pm.
The speaker will be Randy Cunningham of AstroSystems http://www.astrosystems.biz Randy will demonstrate some short f/ratio truss Newtonian telescope components. Short focal length telescopes present several challenges, most are related to the need to achieve greater relative accuracy of collimation, or optical alignment, and holding it.This requires new tools and techniques for collimating, optical support components that give easy, accurate alignment and hold it, and a support structure utilizing optimized materials and engineering to meet these demands.
