Solar Telescope Online

Part of the telescope array in our observatory is a 60mm Lunt Solar telescope with a hydrogen-alpha filter.  The solar telescope has the ability to view the Sun directly, and an Atik Infinity CCD camera captures the images.

The hydrogen-alpha filter is an integral part of the telescope, and filters out all light except for a very narrow slice of the visual spectrum centered on the frequency of light associated with electrons in atoms of hydrogen dropping from a high energy level back to their original orbits in the atom.  The hydrogen-alpha wavelength is 656 nm.

When you look at an image of the sun through a hydrogen-alpha filter, solar prominences, flares, and convection cells become visible.  The latest image on the Wall Township Public Schools Observatory page features a close-up of the solar disk and a moderate-sized solar flare visible at the lower-right corner of the image.

More solar images will be posted as they become available.  We are also planning on a live video stream from the solar telescope, which should be available soon.
