# 引言
|
||||
Asi air Pro硬件层面是一款基于树莓派4开发的天文摄影控制系统,软件层面是基于[indi lib](https://indilib.org/)进行二次开发的产物。
|
||||
## 源头
|
||||
最早了解到Asi air是在论坛中无意翻到的,当时笔者只有一个星野赤道仪(艾顿star guider pro)、单反(D3300)、望远镜(裕众60ed apo),时下并不清楚何谓“导星”,以及Asi air可以做什么。后续在Google搜索相关资料的过程中,学习到了goto、导星、冷冻相机、eaf等等器材和知识,逐渐意识到这么一款控制系统可以帮助天文摄影爱好者甚多。无意中浏览到一篇[“ASIAIR Pro开箱拆机评测”](https://pi.bestxtech.com/reviews/asiair-pro/)的文章,了解到它大概是基于树莓派4二次开发的系统,后续搜索中了解到其系统是刷在SD卡中的,且有系统恢复镜像可供下载(提供给系统损坏的人恢复使用),且根据其使用时无需联网断定认证过程是发生在离线环境。因此决定逆向ASIAIR,于是有了这篇文章。

## 树莓派介绍
|
||||
|
||||
|
||||
### Asi air Pro基于树莓派的二次开发
|
||||
> 树莓派(英语:Raspberry Pi)英国树莓派基金会开发的微型单板计算机,目的是以低价硬件及自由软件促进学校的基本计算机科学教育。
|
||||
|
||||
> 树莓派 4 代(Raspberry Pi 4)是树莓派基金会几年 6 月底发布的最新一代微型电脑,相比于树莓派 3 全方位升级,用 USB-C 接口替换了之前的 USB micro-B 电源接口,支持更大的功率。两个 HDMI D 型接口(Micro-HDMI)取代之前的 HDMI A 型接口。内存 1 / 2 / 4GB 可选,还升级了蓝牙 5.0,千兆以太网,USB3.0 接口等等,价格依旧是 35 美元起。

## IndiLib介绍
|
||||
>INDI Library is an open source software to control astronomical equipment. It is based on the Instrument Neutral Distributed Interface (INDI) protocol and acts as a bridge between software clients and hardware devices. Since it is network transparent, it enables you to communicate with your equipment transparently over any network without requiring any 3rd party software. It is simple enough to control a single backyard telescope, and powerful enough to control state of the art observatories across multiple locations
