Simon, no problem! More a case of letting it be known that there are larger aperture alternatives now around.
For what it's worth, a 5" SCT is a good option too. I had a C5 for many years & found it to be a very capable instrument. Some aperture, focal length, photo capable, & with a tight butt too. Even 6" SCT. Would be a good compliment to your 8" dob (won't shake in its boots so much either
)
