Solar Observation

Solar protection.
Solar telescopes are equipped with protective filters radiation type IR/UV cut for safe and convenient solar observation.




Observation in our observatories as long as the measures against Coronavirus (COVID-19) prevail, will be carried out with artificial means of special cameras and screens and with the use of a mask.


Observation of photosphere at 540nm ( green).
The Skywatcher Equinox-120 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 spot groups, shadows, the penumbra and the torches. Furthermore there is the option to view the solar image on projection screen (monitor) with a diameter of 50 centimeters . Solar telescopes have focused type crayford with steel runners and decimal division for precision focus.

Chromosphere observation. (red)
Filter hydrogen (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 D = 60mm and BF10 in 656,28nm, we 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)hydrogen filter we can see the deeper layers of the atmosphere of the sun. The impressive chromospheric phenomena are rapidly evolving and are perceived observing within minutes. Sun spots, torches, projections and flares can be observed almost
daily (weather permitting) through the optics but also through CCD camera and monitor. It is also possible from the visitor to take pictures.

Observing the sunlight with the spectrograph – spectroscope
Although it is relatively rare for someone to observe the sunlight through a spectrograph, we however in the observatory of Astronomy Cafe of Rhodes, allow guests to observe the analysis of sunlight with a high-resolution spectrograph (reflective barrier 1200 lines / mm 12,32Å / mm).

The observer will notice the solar spectrum dotted by hundreds Fraunhofer absorption lines with a backdrop of breathtaking colors of the iris (the rainbow!!). Besides ophthalmoscopic observation, we can add a camera for photographing the solar spectrum.
