12 屏 · 天文与观星A sky app that answers whether it is worth going outside
Twelve screens of a stargazing app built around the question a sky chart never answers, which is whether tonight is actually worth the cold, with every altitude, rise and set time, moon phase, brightness ratio, magnification, true field and exit pupil on every screen computed from one sky and one set of optics rather than asserted beside them.
设计系统加上全部 12 屏，一条提示词全带走。如果只要其中一屏，每一屏也都有自己的免费页面。
设计系统
随套装附带的一个文件。每一屏都把这些数值写在自己里面，好让它能被单独取走；构建会拒绝任何画出这个文件未命名颜色的屏幕。

流程
按人们遇到它们的先后排列。这是应用自身的顺序，不是一份分类清单。
Tonight
4What is above the horizon right now. The sky drawn as it actually stands, one object opened to its whole night, and a moon thin enough to be out of the way.
Planning
4Whether to bother, and what to point at. Cloud and seeing by the hour, the events worth setting an alarm for, and a list filtered by what your sky can actually reach.
The record
4What you saw and what you saw it with. Sessions logged with their conditions, and an eyepiece case where every figure is the optics rather than the marketing.
