This globular cluster is easy to find and nicely observable even in good binoculars,
by locating the 6th-mag star 9 Sagittae half-way between Gamma and Delta of
that constellation. It is 13,000
light years distant.
I take this image through a Celestron 9,25 at f/3,3 on Pixcel 237 CCD. LRGB
image are composite of 15x30 second exposure of luminance layer and each of
RGB component 10x30 second exposure.
