Mounted a tiny skywatcher ED65 on my NEQ6 with an off axis guider as shown in the picture below and found that i needed a field flattener . However with the off axis guider it was impossible to incorporate the flattener so i used the ED120 as the guidescope with the ED65 mounted on top .The test picture below is 15x300sec subs of the cats paw nebula . gives a nice field of view, not perfect ! will have to do more to support the ~1kg camera on the end.
