Dimensions: 45" x 110"

Magnitude: 10.5
Notes:
It was discovered by William Herschel in
1785.
Observations:
C8 at 104x. It is large, bright and
featureless. There is just the slightest hint of
a ring— it may be my imagination.
Herschel claimed it was resolvable!

Surface brightness: 13.0
Class: SB(s)m pec
Dimensions: 2.6' x 2'
Magnitude: 10.7
PA: 159
Notes:
It is 100,000 light years in diameter.
A radio source, it appears to be two colliding spirals.
Discovered by William Herschel on February 7, 1785, and first classified as a
planetary nebula. His son, John Herschel, cataloged them under separate numbers, h 1052
and h 1053, in his catalog of 1833. From this catalog, he took them over into his General
Catalog as GC 2670 and GC 2671 in 1864, from where they found their way in Dreyer's
NGC.
Observations:
C8 at 65x. Even, but with low surface brightness. It looks a little like a shrimp with
the tail pointing W. At higher powers, it looks mottled.
C11 at 140x. Large oval with a rapidly brighter middle (4038), tied to a smaller
bright knot (4039)— almost looks like a double (but very fuzzy) star. Some mottling
suggested in 4038.

Its diameter would be 22 million miles.

Notes:
1823: 24.1 @ 214. 22 measurements. The primary rotates at 148 kps and may be
variable. The stars share a large common proper motion.
The star is a member of the Pleiades group and an infra-red source.
From James Kaler's Star Notes:
Algorab-A is a very normal 2.5 solar mass dwarf (hydrogen-fusing) star with a
temperature of almost exactly 10,000 Kelvin (a nice reference point), its radius about
double solar. The orange companion, Algorab-B, with a mass three-fourths solar and a
surface temperature of about 5,000 Kelvin, radiates much more dimly, producing only 0.3
times the energy of the Sun. The contrast immediately shows how only a small change in
- 14 -
Zone 238
stellar mass leads to a huge difference in brightness, Algorab-A 160 times more luminous
than Algorab-B.
At a minimum distance of 650 astronomical units from A, little B takes at least 9,400
years to orbit. From B, A would shine with the light of 500 full Moons. The real focus,
however, is actually on Algorab-B. A high level of infrared radiation shows that the
system is involved with a great deal of dust that is left over from the formation of the
stars. A star is created by the collapse of gas within a cold dark, dusty cloud, the dust
blocking out heating background starlight. "T Tauri stars" are very youthful stars that
have just been created from the interstellar gases, and as such are heavily surrounded by
disks of dust (from which planets may be born). Algorab-B is a "post-T Tauri star" that
has just passed through that phase and is now settling down on the main sequence to fuse
its hydrogen. It appears to be less than 110 million years old (as therefore is Algorab-A),
and has yet to clear the dust out of its system. Algorab-B therefore makes Algorab-A one
of the more unusual stars of the naked-eye night sky, acting not just as a pointer for
Spica, but also as a pointer for rather remarkable Algorab-B.
