Observations of the planetary nebula Me 2-1 were obtained with different setups, in order to analyze some effects of contamination produced by the second-order ultraviolet spectrum in the first-order red, for wavelengths longer than approximately 6000 A. This contamination problem will be discussed elsewhere. Here we present the obervations of Me 2-1, which include a wide wavelength range, from about 3100 to 10,200 A. A comparison with previous results is shown for the wavelength intervals in common. From these data, the most relevant nebular parameters are derived, using lines in the optical and near IR regions. Some parameters corresponding to the central star are also determined. The results are compared with previously obtained values.
