  • Astroclimate parameters of the Kyiv observatories 
    Rieznik, K.; Reshetnyk, V.M. (Advances in Astronomy and Space Physics, 2012)
    Astroclimate parameters such as the atmospheric extinction, the night-sky brightness, and the seeing are studied using the observational data obtained at some Kyiv observatories. The first parameter is determined using the ...
  • High-speed multicolour photometry with CMOS cameras 
    Pokhvala, S.M.; Zhilyaev, B.E.; Reshetnyk, V.M. (Advances in Astronomy and Space Physics, 2012)
    We present the results of testing the commercial digital camera Nikon D90 with a CMOS sensor for high-speed photometry with a small telescope Celestron 11ʺ at the Peak Terskol Observatory. CMOS sensor allows to perform ...
  • Low-resolution spectroscopy of the chromospherically active stars 61 Cyg AB with small telescopes 
    Pokhvala, S.M.; Zhilyaev, B.E.; Reshetnyk, V.M.; Shavlovskij, V.I. (Advances in Astronomy and Space Physics, 2014)
    We carried out high-speed low-resolution spectroscopy of two stars, 61 Cyg A and B with small telescopes. They are known as chromospherically active stars of the K5V (A) and K7V (B) spectral types. These two stars are ...
  • Tests of commercial colour CMOS cameras for astronomical applications 
    Pokhvala, S.M.; Reshetnyk, V.M.; Zhilyaev, B.E. (Advances in Astronomy and Space Physics, 2013)
    We present some results of testing commercial colour CMOS cameras for astronomical applications. Colour CMOS sensors allow to perform photometry in three filters simultaneously that gives a great advantage compared with ...
  • The firrst spectra for the RX J0440.9+4431 from 2m Terskol telescope 
    Simon, A.; Bondar, A.V.; Reshetnyk, V.M. (Advances in Astronomy and Space Physics, 2011)
    We present the rst results on the spectra of Be/X-ray binary RX J0440.9+4431 obtained with the 2m Ritchey-Chretein-Coude telescope with Cassegrain Multi Mode Spectrograph (CMMS) (with R = 14000) at Terskol observatory. ...
