Description
We present our observations of several planetary nebulae in the central zones of the spiral galaxy M33. We combine the abundances we derived for our objects with those obtained by Magrini et al. (2004) for a sample of PNe at larger galactocentric distances. We compare the radial abundance distribution derived from planetary nebulae with the one derived by HII regions and massive stars. We discuss the uncertainties and biases of the abundance derivations in planetary nebulae and HII regions. We show that planetary nebulae, although difficult to observe, are an important tool to investigate the chemical evolution of galaxies.

    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
