 1.11.05, Last observations

A nice surprise. Long terme exposures let the dust tail appear bright an clearly. In dark areas you have now the chance to see the tail very weak with the naked eye (~mag 3,5). But the new moon phase make  good observations and photos senceless in the next days.

*mag  = > light magnitude: Up to mag +3-4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag +6-7.

The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; 3,5 M31 Andromeda, pale shiny oval)
