«We enormously enjoyed our experience with the Acuter Solarus 80 solar telescope... This is not an instrument intended for observing prominences or the finest details of the solar surface, but for sunspots it proved remarkable. The ratio of visual experience to affordability makes it an excellent starter set. With or without a mount, the Solarus 80 doesn't collect dust: it's practical and rewarding enough to come back to again and again.»
