The telescopic gem of Booetes, and one of "the flowers of the sky," is epsilon, also known as Mirac. When well seen, as we shall see it to-night, epsilon Booetis is superb. The magnitudes of its two component stars are two and a half (according to Hall, three) and six. The distance is about 2.8", p. 326 deg.. The contrast of colors--bright orange yellow, set against brilliant emerald green--is magnificent. There are very few doubles that can be compared with it in this respect. The three-inch will separate it, but the five-inch enables us best to enjoy its beauty. It appears to be a binary, but the motion is very slow, and nothing certain is yet known of its period. In delta we have a very wide and easy double; magnitudes three and a half and eight and a half, distance 110", p. 75 deg.. The smaller star has a lilac hue. We can not hope with any of our instruments to see all of the three stars contained in , but two of them are easily seen; magnitudes four and seven, distance 108", p. 172 deg.. The smaller star is again double; magnitudes seven and eight, distance 0.77", p. 88 deg.. It is clearly a binary, with a long period. A six-inch telescope that could separate this star at present would be indeed a treasure. Sigma 1926 is another object rather beyond our powers, on account of the contrast of magnitudes. These are six and eight and a half; distance 1.3", p. 256 deg.. Other doubles are: 44 (Sigma 1909), magnitudes five and six, distance 4.8", p. 240 deg.; 39 (Sigma 1890), magnitudes both nearly six, distance 3.6", p. 45 deg.. Smaller star light red; iota, magnitudes four and a half and seven and a half, distance 38", p. 33 deg.; kappa, magnitudes five and a half and eight, distance 12.7", p. 238 deg.. Some observers see a greenish tinge in the light of the larger star, the smaller one being blue. There are one or two interesting things to be seen in that part of Canes Venatici which is represented on map No. 11. The first of these is the star cluster 3936. This will reward a good look with the five-inch. With large telescopes as many as one thousand stars have been discerned packed within its globular outlines. The star 25 (Sigma 1768) is a close binary with a period estimated at one hundred and twenty-five years. The magnitudes are six and seven or eight, distance about 1", p. 137 deg.. We may try for this with the five-inch, and if we do not succeed in separating the stars we may hope to do so some time, for the distance between them is increasing. Although the nebula 3572 is a very wonderful object, we shall leave it for another evening.
