The ideal way to use the MPCC for visual use with 2" eyepieces is to directly couple it to the eyepiece, via the eyepiece's 2" (48mm) filter threads.

- T2-29: Baader T-2 Expanding Ring, T2/M48. Converts 2"/M48 filter threads to internal T-threads.

This allows the MPCC to be accurately positioned, providing the optimum spacing for top performance and taking the guesswork and error out of setting a continuously variable holder. The rigid coupling also eliminates the possibility of sag or tilt from variable holders, particularly with the largest and heaviest eyepieces. This configuration also enables the MPCC to work without needing any additional back-focus. In this configuration, the eyepiece will actually come to focus about 10mm further OUT than it does without the MPCC.
Since most large Dobs are limited in their back-focus, this may be the only way to achieve coma correction with some eyepieces (short of trimming truss poles..). Dob users will also appreciate the light weight of the MPCC system, which avoids the balance problems of heavier correctors.
For best performance, the corrector should be positioned approximately 55mm from the rear mounting face of the MPCC housing to the eyepiece's field stop (+/- 3mm for best on-axis sharpness). In order to attach and properly locate the MPCC, only 1-3 inexpensive adapters are required.
