Re: "siteching" a Celestron CI-700?
I went down that same rabbit hole but can't find the end now. Digging back through my CI-700 'database" I have found other CI-700 related info I've collected plus there could be a copy of the original "Hercules" page files and photos. I haven't worked out how to reconstruct it yet but there appear to be some photos which may be of use. I'll have a dig through it.
In my original reply I conflated what I thought I remembered of that site with this one regarding the thrust bearing mod.
Not sure if this page is relevant.
A CI-700 OnStep conversion in french, but the photos don't need translation :)
I think the attachment is from the CN archive.
