I thought I would try to make a JWST type image, with the spectral profile of  Sadr (Gamma Cygni) superimposed upon a wide-field image of the star and associated nebulae in this central area of the Summer Milky-Way. Fortunately, the excellent BASS software allows this superimposition to be achieved quite easily. Greg Parker kindly introduced me to the Star Spikes Pro4 software that allowed Sadr to be emphasised and Affinity Photo 2 was used to add the synthetic and stretched spectrum strip to the final image.

Sadr is of spectral type F8 ad is located at the intersection of the asterism the 'Northern Cross'. It is only 12 million years old and is a massive supergiant with a temperature of 5790+or-100 deg K. Sadr is a yellow -white star approximately 1800 light years distant and is the primary component of a multiple star system surrounded by a diffuse nebula IC1318.
