Hi Peter , is this the FC100D you mean , that Takahashi have just released ? . I have only seen good things ( not many yet , but a few on CN's ) written about it on the net .
I have looked thru a standard FS100 f8 and it was very good , actually we could not see anything but what we were looking at , excellent scope , perfect optics and build and if the new FC100D for just over 2k is as good it will a dream come true for many , hell it might even get me to part with my sky90
for one ?.
Brian.
