finderscope
Very wide-spread cluster, best seen in its totality with the finderscope.
In the 10" at lowest power (36x, 1 degree 23' fov) I see a number of
bright stars overflowing the field of view. With the finderscope (fov = 5
degrees) plotted
approximately 35 stars in the cluster. Left of the cluster center is a
double star S571 (two bluish companions at magnitudes 6.7 and 7.2) paired
with a third to make a cute threesome. The bright stars Delta
Cancri or Asellus Australis (lower right) and Gamma Cancri or Asellus
Borealis (upper right) are within the field of view.
Listed
as over a degree and half and containing some 75 stars in total. 525 light
years away and very old, about 700 million years or 10 times the age of
the Pleiades. North is at 12 o'clock, East
at 3 o'clock |
