I entered 1,04mm in the field "extension" as it is the register difference in mm between F-mount and M42. Is that correct?

Well, the register distance for Nikon-F is 46.5 ... M42 is 45.5 ... so in principle the difference is 1mm ... but
the adapter itself will also have a certain thickness ... I must admit I have not seen a M42 to Nikon so far.
So, if this adapter has indeed its own thickness and does not completely sink into the Nikon mount, you
will have to add adapter thickness too ... and that will likely destroy all your plans.
Regarding you concerns with the Adaptall-2 glass ... if you stay with the "SP" lenses, you are likely
on the save side.
