![]() 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. ![]() ![]() You can read more about Barlow Bob and see some of his other articles at Barlow Bob’s Corner #1 – The Sunspotter Solar Telescope The following two articles have been provided by Barlow Bob, founder & organizer of the NEAF Solar Star Party and regional event host & lecturer on all things involving solar spectroscopy. ![]()
