FS60C可用SKY90field flattener照計都應該可以掛。:u_20 http://www.astronomy.com.cn/bbs/viewthread.php?tid=89208睇下 http://www.mmjp.or.jp/takahashi-sb/data/rdc072.htm

The Reducer-C 0.72x can be used with current FS-60C, but it is inconvenient as follows.
1. The camera angle adjuster cannot be used (to focus), but the reducer should be attached
directly to the draw tube. In this case, to rotate the camera, the main tube must be rotated
or the camera must be rotated at the wide ring. Both way is inconvenient.
2. Because of narrow draw tube stop ring, the light on the edge field becomes short.
The modification parts (short tube, draw tube stop ring & draw tube extension) shall be introduced
into the market in future in order to change the FS-60C to FS-60CB type to use the Reducer C-0.72X.
But in this case, the serial number is necessary because in the past, there were several types
至于老款的FS60C和FS60CB的区别,参考以下:
1. Mechanical tube length: 18mm shorter than FS-60C
(On the current FS-60C, if the camera angle adjuster is fixed, the focusing becomes impossible.
2. Instead of shorter tube, the draw tube extension 18mm is added.
3. Draw tube stop ring inside diameter becomes large. (same as FCT-65)
4. Delete the inside tube diaphragm, the tube inside is less shiny painted.
