Can anyone recommend a good focal reducer/field flattener for an Explore Scientific 80mm triplet APO refractor?  Thanks!

I did a comparison of the Orion FF and Reducer here. Hope it helps.

What you want is the one ES specifies for this specific scope.  The shelves of imagers are littered with mismatched flatteners.  DAMHIK.  <smile>

I need to change the thread title.  I have the ES field flattener.  I want a wider field of view for mycamera zwo asi 294mc pro- so I am looking for a focal refucer for it.

ES doesn't make a reducer/flattener for it?

They make a flattener but I not think it is a reducer.
