Very pleased to have got my new home made ex bino optics )  finder scope up and running with great success.  I fitted crosshairs in the eye piece using fibre optic filament which, when magnified gives a somewhat "vigorous" image but absolutely ideal for its purpose..  I had also done  some experimenting with putting cross hairs in a 20mm eyepiece  to assist in aligning the main and finder scopes but as I  proved to myself this is not at all necessary and a waste of time.  The alignment is carried out in daylight anyway ....in my case via a very distant tree on the horizon  and centring the image in the scope field is very satisfactory.
