All the companions are optical.
Wilson measures a star nearby: 1882.62, 96.3@, 8.32", 9.0-9.5. Not found by
Burnham in 1902.
May be optical because Hipparcos gives different distances (690 and 109 light years).

AC 1912: 226.6 @ 134. 2 measurements.
Aa 1976: 0.0 @ 49. 17 measurements.
The B star is a spectroscopic binary (possibly eclipsing) with a period of 8.678 days.
It is also an infra-red source. There is also a third spectroscopic component in a very
long period (1,374.1 days). The primary is a G0 giant; A' is a normal Main Sequence
star; and A'' is a G5 dwarf.
Burnham doubled the primary with a 10.3m companion 1.2 @ 103 during a lunar
occultation in 1883. This pair has retrograde motion.
Observations:
C8 at 65x. It was split in the spotter.
Webb saw them as Y and B. He also wrote "a minute pair between them (Burnham;
13.0m and 13.4m, 6.4" @ 322). Very fine, large field." This faint pair was actually first
detected by John Herschel in 1830.
Moderate field.

Webb said it is a "glorious pair" and noted the strong yellow hue of the primary.

Position: 2059-1238
Type: Oc
Dimensions: 2.8'
Class: IV 1p
Cluster population: 4
Magnitude: 11.0
Notes:
Messier discovered it on October 4, 1780. He claimed to see nebulosity, but there is
none.

Zone 222
Probably not a cluster.
The brightest star is 10m.
The HR diagram turnoff point suggests
an age of 2.5 billion years.
Observations:
C8 at 83x. It is triangular and nebulous
with four stars at the S end. Use high
powers. Under poor seeing, it looks like a
nebula— hence, Messier's inclusion of it in
his list?
C11 at 140x. Small triangular group of
three brightish stars and one fainter one.
14x70 Binos. Hazy patch.

Position: 2054-1232
Type: Gc
Dimensions: 6'
Class: 9
Magnitude: 9.4
Notes:
Mechain found it on August 29, 1780, and Messier added it to his list on October 4 of
that year.
It is 85 light years in diameter and is the faintest of Messier's globular clusters. The
brightest stars are 14.2m and the horizontal branch is 16.9m.
Observations:
C8 at 65x. Ghostly, but not resolved at any power. Very even, and 16 min SW of
SAO 163964 (8.2m).
C11 at 98x. Class: 10. Very faint and unresolved, a bright star lies near it.
14x70 Binos. Small and faint.
