Description
The Cygnus OB2 association contains some of the most massive and most luminous O-stars in the northern hemisphere. As a first step toward studying the initial mass function of Cyg OB2, uvby and JHKL-prime photometry were obtained for about 80 OB candidates in the region. The c1 vs. (b-y) color-color diagram is shown, indicating the main sequence line, approximate types, and reddening line. These results are briefly discussed.

    Phase diversity application on the EST MCAO testbench
    Phase Diversity (PD) is a technique widely used to measure and compensate for Non-Common Path Aberrations (NCPA) in optical systems. Beyond its traditional applications, PD has found further uses in solar astrophysics, where it enhances image quality by processing multiple images to correct residual aberrations. In this work, we introduce a

    First light of the upgraded Gregor Infrared Spectrograph
    For more than ten years, the Gregor Infrared Spectrograph (GRIS) has been the infrared spectropolarimeter on the Gregor telescope since its inauguration in 2012. The instrument mainly performs polarimetric observations of the wavelength regions at 1083 and 1565nm, which have high scientific potential. There, observers can find spectral lines that
