Tony your right, I forgot about the ST-4
focal reducer. (I only use it with the C11) I purchased it used and
didn't get any documentation with it, so I'm not sure how much it reduces the
focal length. I was told it was
the older version of SBIGs ST-4 focal reducer. Its help in place by friction (note the newer screw
in type).
Thanks, Joe.

Joe,
Are you using a focal reducer on your
ST-4? I agree with the group as far as focus goes- it looks slightly
out. I use a suresharp on my C-11, and although it too is tough to use, it
takes time - I go back and forth until I am convinced that the shadow comes in
equally on both sides and "blanks" out.
