Description: Arrowhead-shaped with 9x25 B and the 8x50 finder, but
in the telescope the rich background makes the shape less defined.
Over 50 stars, size about 1/3 of the field. A lot of faint stars
in the background. The telescope was very poorly balanced and it
was difficult to keep it pointed towards M93.
