In this project i have used 60mm achromatic doublet lens with 25 mm metal eyepiece. Scope has a 3 inch by 3 inch secondary mirror. Casing is made of 25 & 12mm rubber wood. Lens is housed in a 70mm Aluminum tube. Here the image of the sun is projected on a white plastic sheet. Scope works on Alt-Azimuth wooden mount, movements are quite smooth as aluminum cradle runs on Teflon pads. There is a small maintenance hatch for focusing the image.

This is a useful scope for schools & colleges for Astronomy presentations. Projection method is safe & effective way to enjoy sun's features.
