Transit of Venus
I am wondering if anyone makes use of a spectrometer when observing. It is
said that the transit of the sun by Venus will yield information about the atmosphere of Venus if a spectrum can be obtained. I know that spectrometers are used for star composition. Maybe this can happen with Venus. T

Take a flat-field 'gram first? -- Jeff
