不再是“没有赤道仪不改机硬拍了”，哈哈
身处广西的4级区，刚拿到赤道仪就是连续的阴雨天气，没想到昨晚突然放晴，就直接楼顶开拍。虽然有人放烟花，中途也有起云，但视宁度一直很不错，这是在四级区为数不多的机会。我终于体会到对极轴的麻烦。先用相机借助北极点附近的几个星瞄准北天极，预留云台点头的量，再架上赤道仪。效果也很喜人：24mm叠加可见满天的星团和冬季银河，甚至看见玫瑰星云的影子；135mm 30秒单张就可见M42的整个圈、M78、火树和一点点马头，叠加甚至出了一点点巴环。可惜这次平场没拍好，DBE吃掉了一点巴环。构图纠结于纳入M78还是纳入女巫头，但是想想这镜头彗差太厉害，就只顾了火树马头和M42；但是后期又发现M78进来了，就没忍心裁掉。
