Beautiful Double Cluster in Perseus

If you hobbies in Strargazing you might known this famous object, yes its double cluster in Perseus.
Some 7,000 light-years away, this pair of open or galactic star clusters is an easy viewing with binocular.
located on starfield in the northern constellation Perseus. Also visible to the unaided eye from dark sky areas.
you can find them on evening night sky for November until january.
in suburban area or location near the city, you might able to see with poor image because it interfere with light pollutan from city light.
for best view, i suggest to choose the right location with dark sky condition.
dark sky condition usually appear on high mountain, desert, village that far away from city, or in the beach.

double cluster in Perseus it was cataloged in 130 BC by Greek astronomer Hipparchus.
scientific name for the double cluster is “h Persei and chi Persei”, or NGC 869 (above right) and NGC 884.
seeing with Binocular is best choice because both cluster can appear in target view.
the clusters themselves are separated by only a few hundred light-years and contain stars much younger and hotter than the Sun.
In addition to being physically close together, the clusters’ ages based on their individual stars are similar, evidence that both clusters were likely a product of the same star-forming region.
