For example Evered Kreiwer (one of the authors of the Messier`s album) has taken pictures of the Pleiades from his observatory in Prescott, Arizona with 12 1\2 inch (320-mm) f\7 Cave reflector. The stars of 16 magnitude are cached with 10 minutes exposition over a chilled emulsion. When he copied them, so that he can see one nebulae he used a special mask (look at the picture). The most difficult cached nebulae in this cluster is around Merope which is known as IC 349. John Mallas (the other author of Messier`s album) looked for this nebulae in vain. Finally in the clear sky of Arizona, with 4 inch f/15 Unitron Refractor he found a misty oval spot with Merope in its north part. Usually for IC 349 when the sky is clear and really dark we need 6 inch (150-mm) telescope. Unexpectedly observation of the nebulae around Maya, Taygeta and Cel?no is also possible. In a 4 inch telescope they were observed as misty stripe of light with an irregular form passing transversely across the stars, like the representation from the Kreimer`s photograph. The nebulae around Alcyona can also be observed, but it is very weak and difficult to describe.
