Brixner Telescope Lens Optical

Light from the object being viewed is collected by the concave primary mirror and reflected to a smaller, secondary plane mirror (sometimes called the "flat"). The flat is inclined at 45 degrees to the axis of the Brixner telescope and reflects light to an eye lens which forms an image.
Others will make use of the power they now have to check, test, and analyze new telescope designs. The design and raytrace programs available as an option to this book will give you the tools you need to begin with a basic design and work systematically until you have created an optimized optical system that meets your personal design criteria. You'll be able to try new types of glass, design a telescope around that corrector shell you have parked in the basement, even compare the performance of many different eyepieces on your Brixner telescope.
