I need some help in understanding how I must build a direct mirror of your system because I am not either good at physics or mathematics.
Nevertheless I am interested in trying your system myself exactly as you use it yourself.
But I will need more information please in the practical sense.
I have just visited this link you posted above.
In the first post you wrote;

A la place de la raynox 150 prendre plutôt une 250.... Ça dépend du capteur.
Si bridge prendre une raynox de plus et si possible la raynox 250 pour raccourcir le montage.
If the translation is good then it would appear that the attachment referred to is a parts list.Google translation wrote:Attached is a file with the material to which one must add a manfrotto plate 454 and at least one attachment manfrotto 394.
Instead of taking rather a Raynox 150 250 .... It depends on the sensor.
If taking a bridge over raynox and possibly the Raynox 250 to shorten assembly.
Could you post this please? Will it be in the order of construction starting from the camera please?
Also there is the photo you posted above.
Could you also post the parts list for this arrangement please in the order they are placed on the camera please.
Many thanks, Frederic.
