I finished my 9.2 inch truss tube recently. Did all my figuring based on ronchi images and star testing. Ronchi appeared same as computer generated images. Star test shows slight overcorrection or slight tde. Ronchi shows no tde so it is probably overcorrected. 

Went and observed with my newly coated mirror last night and i was impressed but i know the mirror isnt perfect. Bright stars will have a glow around the fov. Stars are pinpoint. Intrafocal images are fuzzy while extrafocal looks great. Moved my telescope across the sky and found a globular cluster. It was beautiful and at 275x the stars were many in the core. Not sure what cluster it was as my astronomy skills are rusty. It was a beautiful site and a satellite streaked across the globular cluster and gave me the chills. Finally i am observing again and its simply awe inspiring.

Thank you all for the help and i will update my webpage soon. I am working hard on getting my 14.5 inch quartz mirror ready for my father for okie tex star party. I dont know if ill be done in time but maybe i can do the figuring of the quartz mirror at okie tex under the dark skies using the star test!
