Scheiner photographed the "California Nebula" NGC 1499 with a 4" f/3.3 Voigtländer Euryskop (exposure time 6 hours) in Nov. 1893 at Potsdam Observatory; see: Über den großen Nebel bei x Persei (NGC 1499), AN 132, 203 (1893), which encludes the nice sketch shown below (mentioned by Dreyer in the notes of the IC I). On Oct. 27, 1891 Friedrich Simon Archenhold (1861-1939) found the nebula with a 3.1" f/2.5 Busch portrait lense (exposure time 32 min) at Halensee, near Berlin (see: AN #3082). But it was first seen visually by Barnard on Nov. 2, 1885 using a 6" Cook refractor at Vanderbilt Observatory; see: Sidereal Messenger 5, 27 (1886); ApJ 2, 350 (1895).
