David Arditti is quite right about after sales service. I know of one imported Hydrogen alpha scope which had the unusual problem where the image in that waveband became opaque after several years of use. The diagonal part containing the faulty component was returned via the UK supplier to the USA, and a new part obtained gratis. Had this been purchased by the individual I imagine the process may have been considerably more difficult.
