Ghost of Jupiter, NGC 3242
NGC 3242 is planetary neblua in constellation the Hydra. Image of the nebula is at the bottom of the photo. The spectrum of the nebula and stars are projected to up left from the image. Spectrum of the nebula is very strong at wavelenght 656.3nm (H-alpha) and 501nm (OIII). The spectrum is dim at infrared wavelenghts that includes 672nm (SII). Ultraviolet part of the spectrum is not visible because the atmosphere strongly absorbs ultraviolet radiation.
