The Gregor instrumentation and the proposal submission process is described at: https://www.leibniz-kis.de/en/observatories/gregor/observations-with-gregor/
In 2025B the GRIS spectropolarimeter can be used with two simultaneous arms in Ca II IR and He I 10830, or in its flexible one-arm configuration (with a long slit or with the image slicer IFU). As before, HiFI+ offers near-diffraction limited imaging with 50 to 100 frames per seconds in six spectral windows: Ca II H, G-band, blue continuum, broad- and narrow-band H-alpha, and TiO. The conventional AO system was recently upgraded with a faster Tip/Tilt mirror leading to an improved performance. All observations can be executed either in person on-site or in remote mode.
