Coronado manufactures products which allow you to directly observe the sun, as opposed to merely photographing or otherwise indirectly observing it, and they do so with 100% safety for the viewer. Gazing directly at the plethora of everchanging details within the sun is a thrilling experience indeed.
There are two options for observing with Coronado's systems: supreme quality sun-specific refractor telescopes which provide more detail of our star, and a system to adapt your own telescope to be used. The latter requires the purchase of a SolarMax filter, a BF-series Blocking Filter and an adapter plate specific to your telescope.
The SolarMax 40 telescope is an incredibly-portable 400mm scope designed to revolutionize solar viewing. At a hair under three pounds, you take it just about anywhere, which is exactly what the thousands of owners worldwide do. This version comes with the BF-10 blocking filter diagonal, as opposed to the BF-5, so if you intend to use the blocking filter and a SolarMax series filter with another scope you'll be able to do so with focal lengths of up to 1000mm.
