Spectra of planetary nebulae obtained at the AZT-8 telescope 
(0.7-m, Fesenkov Astrophysical Institute, Kamenskoe Plato, Almaty, Kazakhstan)
during 1970–1998. Observations were carried out with a diffraction spectrograph 
equipped with the UM-92 image tube, in the 4000–8000 Å range, 
recorded on A-600 and A-600U photographic plates.</description><referenceURL>https://dachs.fai.kz/spectra_pn_archive/q/sdl/info</referenceURL><type>Archive</type><contentLevel>Research</contentLevel></content><facility>Fesenkov Astrophysical Institute</facility><instrument>AZT-8</instrument><coverage><waveband>Optical</waveband></coverage></ri:Resource>
