Field Flattener for Orion ST80 APO

Hi All,

I am looking for some advice on a field flattener for an Orion ST80 (Not the ED but the APO that comes as part of the Orion Awsome AutoGuider Package), I have managed to get some reasonable shoots through the scope but can definitly notice the field curvature on the endges.

The telescope only has a 1.25" focuser barrell so the Field Flattener must be 1.25" and that is where I seem to be having trouble.

Any suggestions welcome.

Many Thanks

Anthony
