Detecting companions to Cepheids is difficult. In most cases the brightness of the pulsator masks the fainter secondary. Since Cepheids play a key role in determining the cosmic distance scale it is crucial to find binaries among the calibrating stars of the period-luminosity relation. Here we present an ongoing observing project of searching for

Hunting for eclipsing Post Common Envelope Binaries from SDSS
We give an overview of a project aiming to identify new eclipsing post common envelope binaries from the Sloan Digital Sky Survey. This work focuses on the methodology used to identify such systems, describes the follow-up observations and reports on the results obtained so far.

Hybrid instrument for turbulence detection: wavefront sensing and scintillation detection in a fully automatic device
In the planning stage of extremely large telescopes, site testing and study of high performance adaptive optics systems plays very important roles. Site testing is a very time consuming task, therefore, we have built a fully automatic device - the CUTE SCIDAR instrument with a user-friendly interface and real time processing. This instrument is

Hα emission line sources from IPHAS (Witham+, 2008)
We present IPHAS positions and photometry for 4853 sources selected as having a Hα excess from the photometry. The catalogue covers the magnitude range 13

Hα kinematics of 11 starburst galaxies selected from the Sloan Digital Sky Survey
We present analysis of Fabry-Perot interferometric observations for a sample of 11 starburst galaxies with redshift z ≲ 0.03 selected from the Sloan Digital Sky Survey. We have targeted the Hα λ 6562.78 emission line at spatial sampling of 0.2arcsec-0.4 arcsec and at spectral resolution of R ˜ 16 000. Studying two-dimensional maps for the velocity
