Folks, is there a focal reducer field flattener that will work with an 80mm F6 and 127 F7.5 scopes?   I use both scopes for imaging.  Thanks

Sure, but not well.

 

The best field flatteners are the ones designed and /or manufacturer approved for a specific scope.  The field curvature of those two scopes is going to be different.

OK, I have an older Meade 127 F7.5 apo.  I haven't been able to find a focal reducer field flattener for the scope.  The new Meade is 130 F7.  Will that unit work with my scope?  Or can someone recommend a unit that will work?  Thanks

TSRed 0.79x 2" or 3". These work for any refractors between f/6 and f/8. You will need to play with the spacing.
