I’m not really an Alpy expert but I do agree that looks a bit odd. Was it taken in darkness or daylight? Just in case stray light might have been getting in. Also, do you know if that bright “line” is oversaturated and do you have an approximate idea of its wavelength from your wavelength calibration.
