I agree the 65mm objective is the main reason that the picture quality is not as good as the scopes equipped with 80mm objectives. However, you can improve the sharpness if you step down the aperture to f5.6 or f8.

Can you share with us how your adaptor looks like?

My way to custom-made adaptor is to find adaptor rings with inner diameter that match the eyepiece and the camera lens, then linked them up
For Fuji31fd, the diameter of the lens is 30.5mm
I found out that 34mm male filter ring have inner diameter of 30.5mm, which after a bit more polishing, fit sluggly to the Fuji31fd lens
The outer diameter of the 23/30x eyepiece and the 30/40x Zeiss eyepiece is 49mm. Usually a 52mm male filter will fit. And I am lucky to find an old lens hood that again fit sluggly to the rubber.
All the materials were found in 2nd hand camera shops near and around Chan Hung Camera in TST. It costs me less than $200 and these pieces are "modular"!
