Found by taking the distance between Kaus Borealis and δ Sagittarius, then going that distance again above δ Sagittarius.
This was a very large open cluster. I initially attempted to view it through the 25mm eyepiece but because fo its size went to the 40mm eyepiece to see a larger starfield. Was not disappointed! The two lines of curved stars looked like insect antennae, its body sort of defined. There was also an arc of stars in the lower right quadrant of my FOV.
