[ATM] JSP Easytester eyepiece question

[David Cohen <davelcohen2000@yahoo.com>]

A question to the optical fellows out there:

Any of you familiar with the JSP Easytester?  If so,
please answer these questions:

Can the E.T. be used for a Rochi screen focuser for an
SCT like the Meade LX200 F/10? (After all, it is a
Ronchi screen eyepiece, right?).  I know that's not
what it's designed for.

If so, can it be made parfocal to a CCD like a
Starlight Express MX-716?

If not, any ideas on converting an old eyepiece to a
Ronchi screen adjustable focuser?

Thanks in advance and clear skies.
