Rather unusual object, recall having trouble detecting in mediocre sky with
the ETX90, this night was much better than average, tho stray lights could
easily make out the Arrow and the Globular was easily seen even in low power.
60X seemed to work fine, first glance thought the stars would resolve but failed
to do so. Easily find the Arrow by looking above the Dolphins back and below the
famed Cygnus Double - Alibireo. Is just below the front of the Arrow. Looked
abit irregular in shape to me. ..<>.. A good night makes it easier ..<>..
