which field flattener for orion eon

[Jackstar]

Hi all,


I am after opinions/experience from anyone with the performance and suitability of a field flattener on the Orion Eon 115m.
805mm
F7

The situation is that the dedicated orion field flattener:

is unavailable and, other than finding one secondhand or left sitting on a shelf somewhere, i will have to find a different one.


options seem to be possibly the meade one

or this one from Telescope express

If any one has any other suggestions i am interested.


thanks


Jack
