In Gemini, forms an isosceles triangle with the stars Tejat Prior and Tejat Posterior and whose Cr 89 occupies the top, pointing towards north. It is a very wide regrouping, offering a beautiful spectacle to the binoculars. There is no nebulosity in the background and I distinguish 16 stars separately: 6 very brilliant, 5 moderately brilliant and 5 others of low brightness. Moreover, I observe a double star in the Cr 89 western part whose components are of the same brightness. The identity of this double star remain unknown.
