Description
Solar Observation
Solar protection.
During the solar observation, the eyepieces use special filters for cutting off the (IR / UV) ultraviolet and infrared rays as well as certified solar filters.
NEVER LOOK AT THE SUN WITH NAKED EYES. RISK OF BLINDNESS.
The duration of the solar observation is about 60 minutes and you will experience it live with the owner of Rhodes Observatory, Stergos Manolakas. The observation begins with the introduction and explanation of the solar telescopes and filters as well as a summary of solar phenomena. We analyze the light in the colors of the spectrum and then we start observing the sun. After the observation we start photographing the sun together with a special camera.
Then process the images of the photosphere, the chromosphere and all the solar phenomena on the surface of the sun. With this process, many details become visible and perceptible that during simple observation with the telescope are very difficult for the eye to perceive. When finished, we send you by e-mail the processed photos as a souvenir of the solar observation. We would like to inform you that the star of the day is alive and the phenomena can vary in terms of their activity.
Observation of photosphere at 540nm ( green).
The Skywatcher Equinox-100 Pro 120mm 900mm ED-APO Refractor Telescope with 2″ prism Hershel filter Continuum at 540nm (green). With the help of long focal length of the instrument is extremely easy to observe formations of Sunspot groups, shadows Umbra and Penumbra and the Sunspots. Furthermore there is the option to view the solar image on projection screen (monitor) with a diameter of 50 centimeters . Solar telescopes have focused crayford type with steel runners and decimal division for precision focus.
Chromosphere observation. (red)
The Coronado Hydrogen Filter (Ha) in 656,23nm with Front Etalon D = 60mm and BF10, With refractor ED80 Pro-Series diameter and 80mm focal length F600mm with focal ratio f/7.5, in combination with hydrogen filter Ha Front Etalon are able to see the chromospheres (the solar atmosphere).
Rapid changes in the chromosphere, (within a period of even a few minutes), give us the opportunity to see extensive formations explosive projections (jets of glowing hydrogen with dimensions exceeding sometimes and 500,000 km !!!) and solar flares that are extremely violent phenomenon that occurs in the solar chromosphere.
With the help of the regulator (tuner) the hydrogen filter we can see the deeper layers of the atmosphere of the sun till 5000km deep. The impressive chromospheric phenomena are rapidly evolving and are perceived observing within minutes. Sun spots, garnulation, projections and flares can be observed almost.
