Abstract
High-quality parabolic mirrors, which are vital components in reflecting telescopes, are typically bulky, costly, and highly fragile. This experiment explores the feasibility of using specular Class B Mylar as an unconventional, lightweight, and cost-effective alternative. This approach could enable new telescope designs by greatly reducing weight and manufacturing expenses, while also opening options for potential adaptability. This approach involves using Mylar, a flexible, reflective style of plastic. The mylar is formed into a concave mirror by stretching a sheet over a chamber and pressurizing one side to force the sheet into the necessary curved shape. Multiple designs are being created and tested to create the curved membrane shape, all of which operate upon the same principle. By controlling the pressure applied to the sheet, the curvature of the mirror can be adjusted, therefore creating an adaptable focal ratio. This adaptability could enable real-time adjustments directly from the primary mirror, potentially enhancing the versatility of any telescope utilizing this mirror design. To evaluate each mylar mirror design, they will all have a standard 8-inch diameter with an approximate focal ratio of f/6. Each design will be placed into a custom-designed modular telescope frame with a standard polished glass mirror as a control. Performance metrics will be both qualitative and quantitative, including optical clarity and the Foucault test. This experiment could lead to new, cheaper methods of observational astronomy for amateurs and researchers alike.
