Hi Eric

Hmm, just tread carefully Eric, your dreams may come true and you could end up owning a C9.25. Then, the problems will really begin!
  • The C9.25 has a native focal length of 2350mm and with the F6.3 Reducer/Corrector that comes down to 1500mm and even on my (very expensive) Takahashi EM200 mount, I end up throwing away half my images due to non-round stars on long exposures even whilst auto guiding.
  • The C9.25 will still require collimation, although once mastered is quite straight forward.
  • The corrector plate is vulnerable to dew – you will need dew heaters as well as the dew shield.

So, the C9.25 will offer you many challenges and I believe an instrument in this class is unlikely to just plug and play “onto my EQ6 mount without any sort of issues”.

Cheers

Dennis
