Notes:
1830: 8.4 @ 146. 75 measurements. This star rotates at 165 kps. The stars share
common proper motion.
Observations:
C8 at 83x. Webb saw them as W and bW.
C11 at 115x. Y! and B, nice color combination. The galaxy NGC 7490 (13.1m but
large) is located about 1 deg S and showed up, at 311x, as a very dim hazy disk without a
sharp nucleus. I rated it 5.

(1.92 day period and 13.04 day period respectively).
A is a very close binary (discovererd by Burnham as Bur 1266, in 1891 at 0.2 @ 43 in
1996). The orbital period is 48.8 years. The semi-major axis is 0.20" and the motion is
retrograde.
There is also a very faint companion (13.80m) at 36.8 @ 8 (1916).

AC 1852: 264.1 @ 96. 6 measurements.
This star is an infra-red source, and rotates at 188 kps.
All the components are optical.
From James Kaler's Star Notes:
From Arabic meaning "the shin," the name has nothing to do with the horse, having
been misplaced from another constellation, though it is sometimes translated as "the
foreleg."
Scheat has a fairly low surface temperature of about 3,700 degrees Kelvin, 65% that
of the Sun, and is categorized as a "class M" red giant or even supergiant, its color quite
noticeable, especially through binoculars or the telescope. Scheat radiates most of its light
in the invisible infrared, and when that is taken into account, the true luminosity climbs to
1,500 times the solar energy output. To produce this much radiation at that temperature
requires the star to be 95 times the solar radius. Consistent with its giant status, the star, if
placed at the Sun, would extend 70% of the way to the orbit of Venus. Scheat is big

Zone 129
enough and close enough that its angular diameter of 0.015 seconds of arc (6-millionths
of a degree) is easily measured, from which we derive the same physical size. Like many
red giants of its class, Scheat is actually an irregular variable star that slowly changes
from middle second magnitude to bright third, a range of half a magnitude that is easily
visible to the naked eye. There is no particular period of variation, and the star's changes
are unpredictable. Scheat is surrounded by a thin envelope of gas, produced by its strong
wind, in which water vapor has been found.
