![]() ![]() The Sunspotter is placed on the swivel stand, to create a simple mount to manually move the solar telescope to track the movement of the Sun. A television swivel stand sits on this platform. A two-foot-square thick piece of sturdy plastic or plywood is placed on the table, to create a stable platform. Upon arrival at a solar observing session, I set up a small canvas camp table on level ground. However, to use it longer requires the ability to track the motion of the Sun across the sky. The Sunspotter was created for use in a classroom for a short period of time. The Sunspotter appears to have been created by Al Nagler, in a seventh grade wood shop class, while the other students made salad bowls. Perhaps the manufacturer should consider selling this product in a furniture gallery store. This wooden folded- Keplerian telescope is constructed using techniques found in a fine piece of furniture. When you reverse the telescope in the cradle, you can observe the Sun from 30 to 90 degrees. You can observe the Sun from 0 to 30 degrees. The triangle-shaped wooden telescope sits in a semicircle cradle. You can observe features on the Sun, in all wavelengths of light, as they would appear in a small refractor. It is reflected off of three mirrors into the 12.5 mm FL field lens.Ī 3.5-inch image of the Sun, magnified 56 times, is projected on to a white viewing screen. After you align it with the Sun, light passes through the 61.7 mm objective lens, stopped down to 57.0 mm. The Sunspotter creates an image of the Sun by eyepiece projection. A group of people of all ages can observe the solar image at the same time. Sunlight passes through a lens and is reflected off three mirrors and passing through an eyepiece that projects the solar image on to a small piece of paper. This unique solar telescope projects an image of the solar surface on a small piece of paper. The Sunspotter product is the safer solar telescope for observing sunspots. The Astronomical League even has a Sun Spotters Observing Award. You can confirm this rate of rotation and observe that the number of sunspots change over the Solar Sunspot Cycle. The Sunspotter (image from The Sunspotter Solar Telescope can be used to safely recreate Galileo’s solar observation. However, there is now a safer way to observe the Sun. He might have lost his sight by observing the Sun through his telescope without a safe solar filter. Unfortunately, he lost his sight caused by illness. The church stated that God was perfect – therefore, the Sun was perfect, without blemishes. This statement angered the Roman Catholic Church during the Renaissance. Galileo demonstrated that the Sun rotated by observing sunspot movements and argued that, based on these imperfections on the surface of the Sun, that the Sun was not perfect.
