September

The Object of the Month of September is NGC188, an open clusterin the constellation Cepheus.

NGC188 is one of the oldest and most northern deep sky object (visible from Earth), only 4 degrees from Polaris.

Studies indicate it is one of the oldest known open star clusters since it rarely passes through the galactic plane.

It can be a challange in small scopes, but is quite nice in 10" or larger scopes. It glows at 8th magnitude with about 130 stars.

NGC 188 was discovered by John Herschel, the son of astronomer Sir William Herschel, in 1831.
