[Photo of M42] • M42 The Great Orion Nebula

The Great Orion Nebula is always beautiful. This photo was taken by the Geisei 60cm f/3.5 reflector with a 10-minute exposure on Technical Pan 6415 film, which was normally reserved for shooting comets. The fine resolution of this film makes the star images sharp. The details of the swirling gases of the nebula can be recorded only by large aperture telescopes.

[Photo of M45] • M45 the Pleiades

M45 overflows the frame taken by the 60cm telescope. This sharp image of the cluster was shot on TP6415 using -210 f/3 telescope with an exposure of 25 minutes. The image is very sharp and nebulous gas appears as if it was swept through by paint brushes. A sight of the Pleiades in the autumn sky gives us some warmth and comfort.
