BAADER SLOAN/SDSS U' PHOTOMETRIC FILTER Size:36mm 2 – HPS version firmwareThe Baader SLOAN u' filter is a precision grade photometric bandpass filter with a central wavelength window around 355. 1nm. In 2000, a new era in photometry began: with the Sloan Digital Sky Survey (SDSS), a 2. 5m telescope at Apache Point Observatory (New Mexico, USA) surveyed one third of the sky in five wavelengths, with windows around 355. 1, 468. 6, 616. 6, 748. 0 and 893. 2 nm. This system was also used for the Pan STARRS project; the broad
