ASIAIR拍攝中，但導星一直飄掉，
印象中ASIAIR預設是沿用上次校準資料，所以不會重新校準，要自己手動清除，或是修改設定

有時候視寧度不太好時，我會把aggressive 值降低

ASIAir Pro Internals

If you have kept up with me on CloudyNights I have done a pretty deep dive into the Pro, which included rooting the device and digging deep into the covers. The ASIAir Pro is a Raspberry Pi 4 with 4GB of RAM and has a proprietary 5v power unit that powers your Astro devices built by ZWO. The Pro is running a 32bit version of Raspbian GNU/Linux 10 (buster). The operating system is loaded onto a 32GB Scandisk Ultra MicroSD Card. Here are the internal pictures of the ASIAir Pro when I cracked it open.

不同於地球座標，天球座標會因地軸的緩慢擺動（稱爲進動）而變化。進動導致春分點以每年50.3弧秒的速度向西漂移（稱爲歲差）。由於春分點改變，帶動座標網隨之變化。這就是星表和軟件需要不斷更新至最新“曆元”的原因。每隔50年做一次變更，當前多數星表和軟件是曆元J2000.0座標（對應2000年）。下次更新將在2050年。

Asiair pro +cem25ec 碰到怪事
 https://familystar.org.tw/index.php?option=com_smf&Itemid=45&topic=37895.msg259924#msg259924

後來確認問題了 cem25ec 先前  align 後 資料 有 offset 存在  重開機還有記 ,  導致  asiair  goto 過去 偏差好多度 .
  這超過 air (聽說 可設 range ? )  顯示 也離目標好多分 差  .  所以 無法居中 . 
前些天把 手把 校正  清除 goto jupiter OK .   goto 過去  目標  跟現在座標也 都對了 .   
 昨晚又 測 m31  m42  ic434  m33  全都能居中 .. 先前 一值困擾好久 .終於解決了.

剩下 就 asiair  對 polar align  .. 還是怪怪的
