vixen r200ss

am at my wits end and could really use the expertise of this group. I own a vixen 8" 800 mm reflector f/4 and all stock accessories to include the coma corrector. When I use it visually and with a dslr it performs perfectly. However, I recently purchased a st-2000xm camera with a gerd neuman filter drawer and cannot reach focus. I cannot rack the drawtube in any further to reach focus. I purchased the 2" nosepiece (baader) along with the 2" low profile adpater (vixen) and still cannot reach focus but I can see I am going in the right direction.
I was told maybe the Denkmeier OCS is the answer but I was also told not to use the coma corrector along with that, I was also thinking of the Clement low profile focuser but then that would add alot of cost (500) plus I could not use the stock coma corrector unless they could make a special adapter so I could attach my coma corrector.
I love the idea of a native f4 scope and I do not want to change the configuration that would impact the focal length any all?
