The Yale Bright Star Catalog
(9,096 stars)
The above zip file "YALE.ZIP" can be downloaded and
unzipped
(extracted) wherever you like. There are 4 files included
Yale1-5000.txt,
and Yale2-9096.txt along with their compiled
versions. Once the SDB's and text files are "unzipped" add the SDB files to the active list
of SDB's using the DatabaseBase Manager.

Click here for details on how to use TheSky's Database Manager.
NOTE: There are two SDB files not just
one with all stars. This is because TheSky6 is currently optimized for
5000 entries in an SDB file. That is not the case with core databases that
can be as large as a million files or more. The next release of TheSky
will overcome this limitation and is in the works ;).
The two SDB files are "Yale1-5000"
and "Yale2-9096". Where the first half has stars 1-5000 and the rest of the stars is located in the second
file (5001-9096). The internal identifiers are "YBSC1" and "YBSC2".
Use the View | Display Explorer to access the SDB data by name
when it has been added to the active list of SDB's.
YBSC1
contains entries 1-5000. See below.

To see that the Yale Bright Stars are plotting correctly use the
View | Stellar Appearance | Catalogs/Astrometry dialog to DISABLE the other
stellar data, the Guide Star, the Hipparcos/Tycho, the UCAC2, and the USNO-B
(subset), etc. NOTE: You may not have access to the
USNO B1.0
full (80 gigabytes) or either of the
USNO A2.0
datasets because they are not distributed with
TheSky. But they are available for
downloading. See below.
Disable all other stellar data
Reality Check!
(Plot only the Yale Bright Stars!)
When the other stellar catalogs are turned off (disabled) the Yale
Bright Stars will be easy to identify. Simply put they are the only stars you
will see!

V/50 Bright Star Catalogue, 5th Revised Ed. (Hoffleit+, 1991)
================================================================================
The Bright Star Catalogue, 5th Revised Ed. (Preliminary Version)

Description (prepared by Wayne H. Warren Jr., 1991 June 28):
The Bright Star Catalogue (BSC) is widely used as a source of
basic astronomical and astrophysical data for stars brighter than
magnitude 6.5. The catalog contains the identifications of
included stars in several other widely-used catalogs, double- and
multiple-star identifications, indication of variability and
variable-star identifiers, equatorial positions for B1900.0 and
J2000.0, galactic coordinates, UBVRI photoelectric photometric
data when they exist, spectral types on the Morgan-Keenan (MK)
classification system, proper motions (J2000.0), parallax,
radial- and rotational-velocity data, and multiple-star
information (number of components, separation, and magnitude
differences) for known nonsingle stars. In addition to the data
file, there is an extensive remarks file that gives more detailed
information on individual entries. This information includes
star names, colors, spectra, variability details, binary
characteristics, radial and rotational velocities for companion
stars, duplicity information, dynamical parallaxes, stellar
dimensions (radii and diameters), polarization, and membership in
stellar groups and clusters. The existence of remarks is flagged
in the main data file.
The BSC contains 9110 objects, of which 9096 are stars (14
objects catalogued in the original compilation of 1908 are novae
or extragalactic objects that have been retained to preserve the
numbering, but most of their data are omitted), while the remarks
section is slightly larger than the main catalog. The present
edition of the compilation includes many new data and the remarks
section has been enlarged considerably.
This preliminary version of the fifth edition of the Bright Star
Catalogue supersedes the published and machine-readable versions
of Hoffleit (1982, Yale University Observatory) and is intended
for use until the final version of this edition is completed. It
has been made available only for dissemination on the
Astronomical Data Center CD ROM.
The brief format description applies to the preliminary version
of the catalog only. The format will change for the final
edition.

Historical Notes:
* 02-Oct-1993 at CDS (Francois Ochsenbein)
A few corrections have been inserted from the CD-ROM version
"Selected Astronomical Catalogs, Volume 1, 1991, directory
/combined/bsc5 at CDS with the agreement of Wayne H. Warren Jr:
1. The spectral type for HR 6397 is from Walborn and contained octal 032
(control-Z) characters instead of square brackets around the "n".
2. Two remarks have been added for 6985 and 8817
3. Byte 197 (NoteFlag) of "catalog" file corrected for stars
202 7126 7482 7614 8982 (removed asterisk)
285 342 841 843 991 1181 1553 1652 2269 2271 (added asterisk)
2837 3133 3962 4522 4789 6692 7076 7328 8306 8667 (added asterisk)
* 02-Nov-1995 at CDS (Francois Ochsenbein):
Documentation slightly changed to accommodate to standards, and
two lines which were inverted in "notes" have been replaced.
