Estimate the angle (in degrees to the nearest integer) subtended by the two close pairs <br /> relative to each other. (The enclosed angle of the two lines going through the two narrow pairs).<br /> <br /> Do not give any PA, only the relative angle of the two close pairs. No drawing is needed.<br /> <br /> If you cannot find e Lyr, the assistant can point to it for you, but only after 5 minutes. In this case you will <br /> lose the marks for pointing the telescope to the object.<br /> <br /> The telescope assistant will check the object at the end of the 10 min limit. If you are ready sooner, keep the <br /> star in the FOV, and wait for the check.<br /> <br /> ==中文题目==<br /> <br /> 任务2 /替代：EPSILON LYRAE<br /> <br /> 可用时间：10分<br /> <br /> 15分<br /> <br /> •找到ε Lyr，用10mm目镜画出视野（画出目标其他星星）。<br /> <br /> 用两个箭头标记北向和东向，并将它们标记为“N”和“E”。<br /> <br /> •估算距离较远的一对（ε1-ε2）之间的角距，并估算这一对的位置角。<br /> <br /> •使用2x Barlow镜头增加放大倍率，以便能够分辨和分离两对更紧密的恒星对。估计两个近距对相对于彼此所成的角度（以度为单位，精确到整数）。 （两对近距对延长线相交所成的角度）。<br /> <br /> 不需要要给任何位置角，只给出两个紧密对的相对角度。不需要绘图。<br /> <br /> 如果您找不到ε Lyr，观测助手可以为你指出，但仅在任务开始5分钟后。在这种情况下，您将丢失将望远镜指向物体的分数。<br /> <br /> 观测助手将在10分钟限制结束时检查目标。如果您早点准备好，请将目标留在视场中，然后等待检查。</div>
