Raleigh Criterion is a fancy way to say 1/4wave . In other words this telescope's name literaly means "minimally acceptable". If it is imported en' mass I would expect to see it rebranded. Ian Anderson www.customopticalsystems.com Herm Astropics http://home.att.net/~hermperez looking at the mount I'd say this is aimed at observatories. given this i'd say it is entierly possible these telescopes could compete with star instruments. if quality is comparable (and the optic set is ritchey) you should expect it to cost at least $30 000 for the set.
