Description: The first impression at 40x is of a very poor group
bright stars. But 63x reveals a moderately rich background of
12-13m stars bringing the total up to 40 stars. A most
interesting central star ("zoomed" in the drawing): only two
components was seen a 40x but wiht 63x a total of 5 stars was
seen within 25''. A somewhat fainter star 1' S also displays
several faint companions. Biur 1 & 2 were also clearly visible
(easier than this ngc-cluster!!) but not in the same field.
