The primary appeared to be white and  the companion I couldsee, I guess it's the C star that's listed on the projects site(S537),looked bluish. I had no chance to see the B star that's listed as being 1.8" distant from the primary, nor the D star which is listed as mag 12.8. Also visible in the same fov was S538, an extra added attraction.;^)

This superb cluster of wide doubles was not expected in this field. It is an arrow-shaped group of 5 stars pointing south and similar to Sagitta at low power.
 
Comment: I have obviously failed to detect any close companion but 
the delightful field is reward enough.

A very tight pair, nothing could be seen at low power or mid power in any way      indicating duplicity. At high power the companion would pop in and out of view.
