secondary mirrorless GSO 8" F4 CONSTRUCTION
Images added to a gallery album owned by Bill Phenix in Member's Album
This project was started a few weeks ago with the intention of removing the secondary mirror from my scope. i used a celestron 8 inch f5 tube and replaced the f5 mirror with a GSO 8 inch f4 mirror. A new mirror cell had to be built so i used the stellafane design as shown in the pics. i was fed up with the secondary dewing up and knew that the heat produced from the camera would eliminate this. 7% increase in light since no secondary. less diffraction since camera is much smaller than the required size of secondary. collimation is a dream, just remove the camera and look through the hole. focusing is done by gently moving the camera. i will be doing some rough tests tonight and will post images in the future. the images shown is of the scope nearly finished, i have to block the hole where the focuser used to be. -
