  Observations of chromospheric spectral lines near and beyond the solar limb
provide information on the solar chromosphere without any photospheric
contamination. For ground-based observations near and off the limb with
real-time image correction by adaptive optics (AO), some technical requirements
have to be met, such as an AO lock point that is independent of the location of
the field of view observed by the science instruments, both for 1D and 2D
instruments. We show how to obtain simultaneous AO-corrected spectra in Ca II
H, Ha, Ca II IR at 854 nm, and He I at 1083 nm with the instrumentation at the
German Vacuum Tower Telescope in Izana, Tenerife. We determined the spectral
properties of an active-region macrospicule inside the field of view in the
four chromospheric lines, including its signature in polarization in He I at
1083 nm. Compared to the line-core intensities, the Doppler shifts of the lines
change on a smaller spatial scale in the direction parallel to the limb,
suggesting the presence of coherent rotating structures or the passage of
upwards propagating helical waves on the surfaces of expanding flux tubes.
