🤖 AI 总结 要点:本文记录了作者用约15美元的二手400mm Sigma XQ镜头加2倍远摄镜头在Sony NEX‑3相机上尝试拍摄国际空间站的经历,利用N2YO.com预测轨道时机进行对准,最终只能捕捉到ISS的微小白点,未能获得细节图像。多次尝试包括使用佳能摄像机和捕捉ISS穿越太阳的日食现象,结果均呈现模糊斑点。作者鼓励读者用更离谱的设备如Game Boy相机进行挑战。 关键数据:镜头焦距 400mm | 远摄倍增 2× | 成本 $14.99 | 相机 Sony NEX‑3 | ISS 轨道高度约 400 km (标题级,需点开看) 技术路径:利用低成本二手长焦镜头配合数字相机,通过在线轨道预测软件精确时机,对准并拍摄高速移动的ISS。 工程权衡:长焦倍率受限导致成像分辨率不足,光学质量与光圈限制在低光条件下噪声大,且手持对准难度高,需精确追踪。
