My skies are now closing
in on me and I am chasing bright, well separated objects. This star marks
the Dog's toenail.
Comments: A dazzling Bluish
white primary with a wide fainter Blue companion. A fine small telescope
object.

Duplicity detected at 96x
Confirmed at 130x. This was a challenging double -
the secondary hiding amid the strong light of the primary. Image was very similar to Rigel.

A very bright yellow star.
I studied this for quite some time at all powers, and with both a neutral
desity and UltraBlock filter in attempt to cut the glare. I thought that
I was able to detect a slight bump to the south, but never got a clean
break.

I thought this would be
a piece of cake previously with a wide separation of 7.5", but failed the
last time! The TV-102 Light Cup having split Antares last year would not
lie down to take defeat ;-). Couldn't split at 44x. Saw
a glimpse of secondary at 73x. A clean split at 110x, very dim and extremely
tiny pin pricked in contrast with the much larger airy disc of the primary.
Both seemed white in color. Secondary disappeared at 146x. Went back to
110x to ascertain; there it is again!. Now, I see why I failed to split
it when the moon was up; no way could the secondary have been seen! Also
umm, the secondary is very sensitive to magnification.
