The bloody clouds running around this afternoon! I spend more than one hour to make just 2 shots! I found that when the Lunt CaK is on Equinox 120ED, it cannot reach focus. I need to use a 2.5X Powermate to make it works. As a result the effective focal length is 2250mm.
APM 80/480

可以像David一樣造個轉接環，用APM上那個羽毛調焦，一來合焦，二來可以採用電子調焦。

A little surgery was done on the Equinox 120 tube to make CaK reach focus. It allows the CaK 2 inch nose tube to go completely into the scope.

調焦筒內端小於２”，我們用車床把那一截內徑車大了一點。
