NGC 6853
Rating: 1 E
Other Names: Dumbbell Nebula; PK 60-3.1, M27
Astronomical Leage Program: Messier Club, Urban Deep Sky Club
Position: 2000+2243
Type: Pn
Dimensions: 6' x 8'
Class: 3
Magnitude: 7.6
Notes:
Messier found it on July 12, 1764. He described it as "oval-shaped and contains no
star."
It is 3 light years in diameter. The central star's surface is 85,000 Kelvin. It is a
feeble 13.5m.
Lord Rosse's sketches show 18 stars involved in the nebula!
Observations:
C8 at 83x. Large and bright, it looks like an apple with two bites out of it. With high
power and averted vision, you should notice a few very, very faint stars strewn across its
face.
C11 at 115x. It is very large and bi-lobed. With the O-III filter, it doubles in size and
has a "bitten apple" look. It is very mottled and knotted. At 193x with the O-III, it fills
the field.
Model (where the Sun is a baseball):
Its diameter would be 674 miles.
Distance (LY): 900
Luminosity (suns): 58

Notes:
It was discovered by William Herschel in 1784.
Observations:
C8 at 104x. A NE-SW oval amidst a triangle of 12m stars. Its blue color is quite
obvious, but I could squeeze no details from it at any magnification. (On the other hand,
Steve Coe says he has never seen blue in this object. Given his skill, that has to carry
some weight!)

C11 at 98x. Large and blue. At 115x + O-III filter, it is much more obvious. It has a
large disc and a suddenly brighter center. It blinks very well. A star is involved in the N
end. It lies at the end of a jagged chaing of seven stars.

It is slightly variable.
It was found by Williamina Fleming in 1896.

Zone 150
Observations:
C8 at 280x. It is a very bright, greenish object with a tiny, tiny disk. I found it by
"blinking" it with an O-III filter— that is, look at the field un-filtered, then place the O-III
filter in front of the eyepiece and look for a non-point source.
A W star lies about 1 minSW.
C11 at 115x + O-III filter. Without the filter, it looks merely like a 10m star just E of
a faint pair. With the filter, it is the brightest thing in the field.

Magnitude: 11.0
Notes:
It was discovered by Edward
Pickering in 1883.
Observations:
C8 at 83x. Starlike. The planetary
is featureless, but use high power to
improve the view. An O-III filter helps
a lot here. Rich field.
C11 at 115x. Without the O-III, it
is barely detectable. With the O-III, it
grows in size but is still nearly stellar.
It lies about 30 sec W of a 9m star.

Its diameter would be 133 miles.

42.2 @ 280. 6 measurements. Star A is a spectroscopic binary that rotates
48.0 @ 330. 6 measurements. Quadrant reversal?
51.7 @ 309. 5 measurements.
80.7 @ 114. 4 measurements.
From James Kaler's Star Notes:
The mysterious names "Sualocin" and its partner "Rotanev" appeared in the Palermo
star catalogue of 1814. A bit of detective work by the nineteenth century English
astronomer Thomas Webb finally disclosed that the stars are the reversed Latinized
names of the assistant to the observatory's astronomer Giuseppe Piazzi, Nicolaus
Venator, so honoring him.
Though at bright fourth magnitude slightly dimmer than Rotanev, Sualocin received
the constellation's Alpha designation from Bayer. This class B star, just over the edge
from class A, has a surface temperature of 11,000 Kelvin. Like most B stars, it is
spinning rapidly, 160 kilometers per second at its equator (70 times faster than the Sun).
Its status is somewhat uncertain, some observers calling it a hydrogen-fusing main
sequence star, others a subgiant that might just be starting to evolve. At a distance of 240
light years, the star appears to have a luminosity 195 times that of the Sun. It has been
known for some time, however, that Sualocin has a close companion a fraction of a
second of arc away. Modern measurements with the Hipparcos satellite show the
companion to be about a tenth the brightness of the principal star, revealing it to be a
class A star rather similar to Sirius. The principal component is therefore a bit less bright,
about 175 times solar. The two orbit each other with a period of 17 years at an average
separation of about 12 astronomical units, a bit farther than Saturn is from the Sun, the
total mass found from the orbit to be 5.8 times solar, most of (over 3 solar masses) in the
main component. Since the brighter star will die first as a dim white dwarf, the system
may someday appear much as Sirius (with its white dwarf companion) does today.
