Fg 1 (He 2–66) is a southern planetary nebula that presents an elliptical shape. Deep CCD imaging and long-slit spectroscopy have been obtained at Las Campanas Observatory of this object. The images were obtained in the light of Hα+[NII], [SII] λλ6716,6731, HeII λ4686 and in the broad-band R gunn filter. The spectra were obtained oriented N-S, P.A. 90°, and P.A. 85°. The instrumental combination yields a spectral resolution of ∼ 2 Å FWHM, covering a spectral range ≃ λλ 6290–6805 Å.
