Mission impossible?

[LT]

沒有使用任何電子極軸鏡，純使用Vixen SX 型號極軸鏡+1次極軸微調。

共試了4張，沒一張有明顯的南北拉線 ==> 15分鐘單軸導星被步目標達成。

Taken with Vixen ED81S II + LPS + modified 100D @625mm F7.7, iso100 RAW
Autoguiding: modified Vixen AP photoguider + 5cm guiding scope + 2x + QHY5 + PHD on RA only
Exposure = 1 x 15min

The AP mount has great potential given its precision, modular design and running on 5V.
