在天空的画布上涂鸦很有趣。你可以使用一种创造性的摄影技术，在曝光时轻拍望远镜，让点状恒星的光在数字图像上跳舞。其结果将是恒星所描绘的一条弯弯曲曲的线条（或双星所描绘的两条弯弯曲曲），可以揭示恒星的颜色。被称为Ghirigori的彩色线条，是由在北方天空星座牧夫座、北极星冠座、蛇夫座和彗发座中发现的恒星组成的，在这幅艺术马赛克中被捕捉到。25颗星星创造了各种各样的彩色曲线，在边界周围被识别出来。当然，温度决定了恒星的颜色。虽然白色的恒星往往接近太阳的温度，但蓝色的恒星更热，黄色和红色的恒星比太阳冷。周末守望：英仙座流星雨

It's fun to scribble on the canvas of the sky. You can use a creative photographic technique to cause the light of point-like stars to dance across a digital image by tapping lightly on the telescope while making an exposure. The result will be a squiggly line traced by the star (or two squiggles traced by binary stars) that can reveal the star's color. Colorful lines, dubbed Ghirigori, made from stars found in the northern sky constellations Bootes, Corona Borealis, Ophiucus, and Coma Berenices, are captured in this artistic mosaic. The 25 stars creating the varied and colorful squiggles are identified around the border. Of course, temperature determines the color of a star. While whitish stars tend to be close to the Sun's temperature, stars with bluer hues are hotter, and yellow and red colors are cooler than the Sun. Weekend Watch: Perseid Meteor Shower
