Hi, I note form an earlier thread that you often need to drill holes to take the GSO 10:1 Crayford focuser.

Are there any manufacturers out there that actually make a direct replacement 10:1 Crayford that will fit my SkyWatcher 10" dob without needing to drill any holes?

I know that Moonlite's need some tweaking to fit my scope as Scorpius had to mod his scope to fit it.

I've looked at specs for 10:1 Crayfords from Long Perng, and Williams Optics, but have no idea if they fit directly sans le drill.

Cheers
Pete
