Since then I've used the WO 72FD f/6 and it also needed a field flattener to illuminate the chip evenly. Its not uncommon to need one.
The other thing you might find is not only is the chip tilted to the objective, but it could also be offset from poorly operating brass compression rings in your focuser. |
Hi Paul
I am using a Chines brand Aquila 80mm f/5 refractor. It has a crayford focuser. Please see the picture here

One thing might be compression rings as you suggested, may not be able hold canon 300d weight or as Mark suggested about collimation.
I will do further testing using lightweight modified philips webcam and see if it gives any idea.
