Page 7:  Xi Scorpii - Delta Herculis


OBJECT:  Xi Scorpii
TELESCOPE:  Meade 10" f/10 SCT
DATE:  06.28.1996 TIME:  12:53 am EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION: 179x LOCATION:  Vicksburg, MI
COMMENTS:  This one appears to be a "Double Double" like Epsilon Lyrae.  The brightest star is yellow in color, while its dimmer companion appears orange when viewed out of focus.  The double to the south has two stars equal in magnitude with no color.

OBJECT:  Struve 1999 TELESCOPE:  Meade 10" f/10 SCT
DATE:  05.10.1997 TIME:  10:34 pm EDT
TRANSPARENCY:  Good SEEING:  Fair
MAGNIFICATION:  96x LOCATION:  Schoolcraft, MI
COMMENTS:  This one is another "Double Double".  This pair of doubles has more variety in magnitude than Epsilon Lyrae though.  The northern most double contains the brightest star.  No color, but white, can be distinguished under the present seeing conditions.


OBJECT:  Beta Scorpii TELESCOPE:  Meade 10" f/10 SCT
DATE:  06.28.1996 TIME:  1:03 am EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  179x LOCATION:  Vicksburg, MI
COMMENTS:  The brilliant primary is white.  The secondary is half the magnitude of the primary and blue in appearance when shifted out of focus.

OBJECT:  Kappa Herculis TELESCOPE:  Meade 10" f/10 SCT
DATE:  05.31.1996 TIME:  11:23 pm DT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  96x LOCATION:  Kalamazoo Twp.
COMMENTS:  Primary is a "sharp" golden-yellow.  Secondary is also yellow, but darker than the primary.


OBJECT:  Nu Scorpii TELESCOPE:  Meade 10" f/10 SCT
DATE:  06.28.1996 TIME:  1:24 am EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  156x LOCATION:  Vicksburg, MI
COMMENTS:  The primary star is bright yellow.  The secondary, after closer examination, was discovered to be a close binary system in its own right.  Color was difficult to distinguish, but seemed a dark yellow.

OBJECT:  Sigma Coronae Borealis TELESCOPE:  Meade 10" f/10 SCT
DATE:  05.31.1996 TIME:  11:39 pm EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  96x LOCATION:  Kalamazoo Twp.
COMMENTS:  These two are nearly identical in color; both are yellow.  The primary is about a magnitude brighter than the secondary.


OBJECT:  16/17 Draconis TELESCOPE:  Meade 10" f/10 SCT
DATE:  05.31.1996 TIME:  11:55 pm EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  96x LOCATION:  Kalamazoo Twp.
COMMENTS:  The two brightest stars in the eyepiece are identical in magnitude.  However, 17 Draconis has a faint yellow companion.  Very tricky!

OBJECT:  Mu Draconis TELESCOPE:  Meade 10" f/10 SCT
DATE:  06.28.1996
TIME:  1:34 am EDT
TRANSPARENCY:  Fair SEEING:  Good
MAGNIFICATION:  313x LOCATION:  Vicksburg, MI
COMMENTS:  This is the closest association I have observed thus far.  The two are absolutely equal in magnitude.  They appear to be white.


OBJECT:  Alpha Herculis TELESCOPE:  Meade 10" f/10 SCT
DATE: 06.29.1996 TIME:  10:09 pm EDT
TRANSPARENCY:  Fair SEEING:  Fair
MAGNIFICATION:  746x LOCATION:  Nature Center
COMMENTS:  The brightest star of this pair is golden-yellow.  At first glance it appeared that the fainter companion was also yellow, but it took on a white hue at higher magnifications.

OBJECT:  Delta Herculis TELESCOPE:  Meade 10" f/10 SCT
DATE:  06.29.1996 TIME:  10:27 pm EDT
TRANSPARENCY:  Fair SEEING:  Fair
MAGNIFICATION:  192x LOCATION:  Nature Center
COMMENTS:  The brilliant primary star of this system is bright white.  The faint companion is either red or deep orange.  It was difficult to tell under the seeing conditions.
