48" Dob project
In June of 07 we started a project to build a 48" Dobsonian for Jimi Lowrey in Ft. Davis TX. The 'scope is finished and has been installed at Jimi's observatory.
Jimi's comment: "This primary mirror is hittin on all cylinders" sums up the optical performance very well. With the Paracor in the focuser, stars are pin points with 4 crisp diffraction spikes on brighter stars. The color we saw under the full moon sky is a good indication of the light grasp and contrast that the optics will provide on a good dark night.
We will present an article in the June issue of Astronomy Technology Today detailing the project from start to finish.
