You could do what I sugested in my first post, and remove the field flattener lens from a Meade or celestron reducer, it is very very simple to do, when you unscrew the locking ring, stand up on a piece of cloth and the lens comes out in two pieces with a small plastic spacer between, lift the top lens off ( this is the flattener, it is nearest the camera end) and then the little spacer, then put the casing back over the reducer lens and put the locking ring back in.....simples, now you just have an f6.3 reducer.

I have removed a few of them to fit into a 2" cell so they would fit inside my 2" focuser, rather than have to screw on the back with the SCT threads, but I kept the flattener in also.

Can't see why it would not work, and a much cheaper option.

I know that this is an older post but I hoping someone can help me.

I have a old meade f/6.3 focal reducer/flattener. I used it with a meade 10"  LX90  SCT (non ACF) in a moonlite 2.5 cml focuser.

I now have a meade 10" LX200-ACF  SCT and want to use the moonlite  focuser with a focal reducer (non field flattener). From the post above it sounds like it is possible to remove the field flattener lens..

The moonlite focuser draw tube is for a meade focal reducer so it is important that I either use a compatible focal reducer or remove the field flattener lens so it will work in the moonlite focuser.

If I remove the lens does anyone have experience with what the new back focus will be (the original back focus was 104 mm)?

Or can someone suggest a better focal reducer which would be compatible with the moonlight focuser draw tube?

Any help or suggestions would be appreciated.   Thanks  Brent
