The astroequipment used for the observing events consists of several telescopes.
The first telescope is a special telescope for Sun observing. It is an intermediate telescope with 80mm lens diameter and has build inside special so-called hydrogen-alpha filter which allows observing details on the surface of the Sun which cannot be observed with telescope equipped with regular filter for Sun observing. With this special telescope we can see the grainy surface of the Sun, the sunspots, the prominences and the filaments (filaments are prominences which we see against the Sun's disc). This telescope can not be used for any other observing except for Sun observing.
The second telescope is small reflector telescope with 6 inch mirror diameter equipped with special filter film for Sun observing. It gives yellow-white image of the Sun and we can see only the sunspots as dark dots on the yellow-white disc of the Sun. This telescope will be used for Sun observing only.
The third telescope is big reflector telescope with 20 inch mirror. We will use this telescope for Sun observing with different magnifications and for this purpose the telescope will be equipped with special filter film for Sun observing. Applying high magnifications we will be able to zoom-in on the sunspots and see them with great details.
Also we will use this telescope for daytime and evening observing of the planets and evening observing of the Moon with different magnifications, from lowest to highest.
And this telescope also will be used for evening sky observing from city locations and from dark locations outside of the city. From city locations we will be able to see several bright and interesting stars and double and multiple stars, and several of the brightest deep-sky celestial objects. From dark locations outside of the city we will use this telescope for complete observing of the night sky. Thousands of interesting stars, including double and multiple star systems, and also thousands of deep-sky objects like star clusters, nebulae, galaxies and so on will be within our reach.
