Re: paleonet Digital cameras and Aristophot

[Mark Purnell <map2@xxxxxxxxxxxxxxx>]

By Pure coincidence we had someone advising us yesterday of how to do this.
The problems regarding capture of only a small part of the field of view
that Patricio outlines can be avoided if you use a digital SLR body with a
35 mm size sensor. These, apparently, are now much more affordable than they
were. You still have to have a custom adapter made to allow the body to fit
onto the aristophot, but it can be done.
