| Hα - telescope for the full solar disk. Main objective lens 180 mm in diameter. Equivalent focal length 5,432 mm. Field of view 34 arcmin. Solar image 50 mm in diameter. Spatial resolution 0.92 arcsec. Spectral wavelength 6,563 Anstrom. Photographic film 80 mm in width is used, frame size 70x70 mm. Flare observations (patrol) and investigations of chromospheric fine structure are being carried on. In its characteristics, is highly comparable with its Lockheed analogue (USA) and is superior to its Opton analogue (Germany) |

Series of filtergrams are obtained with intervals of 1 min during periods of good seeing quality and with inervals of 2-3 minutes in the rest. The exposure time is 30 ms. The images are stored in the graphical format .SPE with 16-bit amplitude resolution (volume of a file is 8 Mb) and can be transformed into any suitable format. The contact address: golovko@iszf.irk.ru
