Older Tak FSQ - extending its native focal length

Dear group,

I would like to extend the native focal length of my original Tak FSQ for some terrestrial work I have in mind involving the rising and setting sun and moon.

Is the Tak Extender-Q the only means to this end ... and only at 1.6x?

Ideally I would like something between 2x and 2.5x but will settle on the Tak Extender-Q if that is the only means to achieving a greater effective focal length.

Thanks in advance.

Perhaps the Baader fluorite flatfield converter. AstroPhysics have it on their site.
