Hi,

I want to acquire a focal reducer (the "opposite" of a Barlow) for my TOA-150. Something in the range of 0.33x or 0.5x. 
At least so that I can image the Sun and the Moon full-disc (1/2 degree) with my ZWO ASI585 camera (i.e. 0.5x reducer).
Can anyone recommend one of good quality?

What do you use?

Any hint is appreciated.

Best regards,
Niels

I expect you know Takahashi only make a 0.7x corrector, don't you?

Yes. That's why I'm asking what other high-quality options are available?

Why not take advantage of better native resolution and just do mosaics?

In short: none that I'm aware would give that kind of reduction and I'm pretty sure any non-tailored options would give terrible results. Incidentally it is way cheaper buying a DSLR and sticking it to the focuser than buying any high end Taka gear, if the purpose is to take pictures of the Moon/Sun.
