Detailed explanation-1: -With a white-light filter on the front of your telescope, the Sun’s light is dimmed to safe levels for imaging. The white-light filter allows you to capture the Sun’s visible surface (photosphere).
Detailed explanation-2: -Hydrogen-alpha filters are narrowband filters. These allow you to view solar flares, prominences, and other associated activity. Unlike other types of filters for astronomical observing, solar filters fit over the front of the telescope, completely covering the aperture.
Detailed explanation-3: -Known as “aperture filters, ‘’ white-light filters fit over the front of a telescope in order to reduce the Sun’s energy to a safe level before it enters the optical system, including your eyes.
Detailed explanation-4: -Telescopes, binoculars, and cameras need solar filters for two reasons: to protect them from intense sunlight and to ensure that you don’t accidentally look at the Sun through an unfiltered instrument. In every case, the solar filter must be attached to the front of your telescope, binoculars, or camera lens.
Detailed explanation-5: -Hydrogen-Alpha (Ha) solar observation is typically done with a dedicated Ha Telescope or a Quark. This type of observation, however, allows for views of the granulation on the Solar chromosphere, along with views of flares and prominences on the Solar limb.
Detailed explanation-6: -Solar filters For white light, a simple “solar film” filter in front of the telescope will do. When photographing the chromosphere, you need rather more expensive kit: an H-alpha filter or a Ca-K. H-alpha filters require careful tuning for optimal results.
Detailed explanation-7: -Try various aperture settings. Use Aperture Priority mode. Partially hide the sun. Move around and take lots of pictures. Try using some filters. Shoot during different times of day. Divide the sun with your camera. Use a tripod and a remote shutter release. More items
