The other method of H-alpha viewing involves a special narrow band filter. For those interested in building one, the basic details are described in the January 1969 issue of Sky and Telescope magazine. It is rather bulky, and thus is used mainly in a heliostat-fed horizontal solar telescope. The instrument has the advantage of rapid tunability not only around H-alpha, but in other spectral lines which show emission, such as the K-line of Calcium. One method of doing this involves using a spectrohelioscope, an image-scanning spectroscope using pairs of moving slits to allow monochomatic viewing of the sun.

Regardless of your hobbies or professional needs, the Internet offers a whole array of applications and programs that you could use in order to complete your projects.H-ALPHA FILTERING SYSTEMS: Unlike continuum “white light” observations of the sun, observing the chromosphere requires a very narrow bandwidth filter centered on the Hydrogen Alpha spectral line (6562.8 Angstroms), which not only reduces the intensity of the sunlight to a safe level, but eliminates much of the photosphere’s contribution to the image. It's a neat and small application that allows you to grab images of the Sun. They're taken by the SOHO satellite and you can save them to your computer easily. The application sports a really small and easy-to-use graphical interface with multiple tools and features at hand. It doesn't come with any customization options, but you wouldn't really need them since the layout is quite intuitive and all tools are displayed at hand. However, it could have used some tips and instructions for getting accustomed to the application faster. You can use multiple tools for getting images, the Continuum section loads the Michelson Doppler Imager view of the Sun, you simply need to select the section in order to view the image. You can also access the US Naval Observatory website to get more information. It allows you to view images taken at a specific date and time, simply adjust the parameters in order to get the image that you want. You can also have the application load the Michelson Doppler Imager view of the Sun, together with the tool for viewing sunspots. The latter displays images that are similar to what you would see through a telescope equipped with a solar filter. It also comes with the option to view an image of the Sun taken with the Extreme Ultraviolet Imaging Telescope at a wavelength of 171, 195, 284 or 304 angstroms. You can also view the Sun's corona taken using the Large Angle Spectrometric Coronagraph.Īll images displayed inside the application can be saved on your computer. All in all, Sun Spotter is a very useful application for grabbing images of the Sun and saving them on your PC.Caution: Never look directly at the sun without proper protection.

The Sunspotter is one of the handiest astronomy outreach tools I have ever used. It is sturdy, striking in appearance, and perfect for use with small groups of all ages. It’s simple to transport and set up - it even includes a built-in handle, and its own instructions are printed on the side. "Is it safe?" That's the question always asked when you are observing the Sun, and the Sunspotter is hands down one of the safest solar "telescopes" out there. There is no filter to worry about scratching, no direct line between the Sun and your eyes. The Sunspotter projects a magnified image of the Sun onto a piece of paper, and the image is large and crisp enough that even fairly small sunspots are visible.
Of course, for solar eclipses the incoming shadow of the Moon is very apparent and easy to observe with a group! Since it uses pieces of paper clipped onto its projection area, visitors can even take turns quickly drawing the disc of the Sun and its spots while in use. The Sunspotter’ s largest drawback is also a notable strength.

It is a fully manual observing system so there is no automatic "tracking" of the Sun. Its field of view is wide enough that you don't need to move it constantly. SUN SPOTTER SOLAR TELESCOPE PROFESSIONAL.
