... The spectrum of the brightest star, our Sun, shows several dark gaps perpendicular to the flow of it?s colours (figure 1). These so called spectral absorption lines where discovered in 1802 by the English scientist William Wollaston. ... Some stars as Pollux show a spectrum similar to that of our sun with strong Ca II and Fe II lines, others as Sirius or Vega show strong absorption lines of hydrogen, others, as Mira show very complicated spectra due to molecular absorption lines (see figure 5). ...

The Python programs offered here result from the development of methodology for processing image data with high precision, in a flexible command line system useful for astronomical and laboratory image processing. ... Alsvid is efficient in robotic and automated or scripted server processing of astronomical images, and also in interactive command line processing for research and visualization. ... In large part it replaces IRAF and IDL when scripted image processing is required. ...

. I was organizing my images today and came across one 1998S taken on the evening of Apr.5,98 (Cookbook245 on 8 inch. SCT, stacked 3 x 4 min. (unfiltered)).
