For the information of those with aperture fever, I have just received a free mailout from Obsession Telescopes (requested by email only 1 week ago!) that has blown me away, and convinced me that an Obsession is the way I ultimately want to go.
Included in the mailout is a DVD that runs for almost 2 hours, with interviews with owners, demonstrations of setting up and cleaning the mirror, how the Servo-cat and Argo Navis operate in conjunction with the scope, how the scope and mirrors are manufactured, and importantly, images that give a real life impression of how big each of the scopes in the range actually is, and how they are used in practice.
I should warn that the sound quality and editing is somewhat amateur. That did nothing, however, to deter my drooling!
