	[full size] [no labels]	Gemini North adaptive optics image of 15 Sge and its newly found companion, 15 Sge B. The data were obtained in the near-infrared at a wavelength of 2.2 microns. The image has been computer processed to subtract the light from the much brighter primary star in the vicinity of the companion.
	[full size] [no labels]	Keck Telescope adaptive optics image of the 15 Sge system, also obtained in the near-infrared. The orientation and field of view are the same as the Gemini AO images.
