star, SAO 174421.  60x showed dense stars at the base of the arrowhead.  110x 
shows about 15 stars at the base, but lo and behold, it looks like smaller 
arrowhead, perpendicular to the main arrowhead, with its tip starting at the 
star GSC 6540:4066 and its base at the stars GSC 6540:3324 and GSC 6540:4146. 
John Mallas also noted its triangular shape through his 4 Unitron refractor.
