Thanks Tony
Yes, the 9.25 is also good for such a mod. What I meant to say was the
standard 8 & 9.25 forks are not suitable for a larger Mak like the Skywatcher 180 or my 7" Intes. These scopes need a longer spacing between the base of the mount and the pivot point of the clamp. I see now I could have been a bit clearer on that point!
Thanks Tony
Now, the CPC 925 mount and that of the CPC 1100 are actually identical. Only difference between the two mounts is the 925 has a pair of spacers to compensate for the smaller diameter of the 9.25 OTA. Tony just pointed this out to me. So if you have or get your hands on a CPC 925, you can do the exact same single arm mod and end up with the same hefty mount as that of a modified CPC 1100!
