C9.25 Reducer and corrector

[trent_julie]

Hello,
I am looking to purchase one of these to flatten my c9.25 for Astro imaging. Has anyone got any experience with these? Or know of something better again?

Trent,
I assume your C925 is not one of the new HD models....
That being the case it's the Celestron x0.63 reducer you're looking for.
There are more expensive options like the Optec NextGen reducers

(I used the x0.5 version for a while - excellent performer.)

Thank you. Sorry just added the link

I wasn’t sure if the x0.63 reducer allowed for a flat field too

The Celestron x0.63 reducer is "claimed" to be a flattener/ reducer - but I'd let the more experienced users comment.
(I only use mine on axis - to focus the target star image on the spectroscope slit gap)

Can't comment on the ASA reducer - no experience.
