The picture of M101 (not the OM101 ;-) is taken on Ektachrome Elite 400
(1993 version) with an OM1 through a 52 cm Newton telescope with f=1958 mm
(so an 1958 mm F3.8!) located at the observatory of Puimichel, the South of
France. The exposure time was about 45 minutes.
Nowadays it would be far more easy to take such a picture with CCD cameras
and computer controlled guiding systems. That's one of the reasons why I
hesitate a little with publishing more of these kind of pictures: go to
www.nasa.gov and you will find the *same* picture in a 1000x better
quality... Personnaly I find the stereo pictures of Uranus&Neptune and Pluto
more fun (see also http://members.nbci.com/_XMCM/photovoogt/index.html).
Even with modern equipment you will need some thinking to take such
pictures.
