| An astronomy teachers best friend, the SolarMax 70 telescope has been designed as a sealed unit with no removable parts other than the eyepiece. Combine this with it's 70mm aperture and you have a dedicated and portable H-Alpha telescope that is ideal for use by both the experienced observer and the most novice. As the SolarMax 70 telescope is sealed no critical parts can be removed and set up is a breeze even for school children. Coronado recommends that all solar viewing be done under adult supervision to ensure safe and effective results.
The SolarMax 70 telescope is in use at universities, high schools, middle schools, and their equivalents around the world. It is actually a version of our first dedicated H-Alpha telescope, Helios I, with technological improvements. All of the telescopes in this line (Helios I, NearStar, SolarMax series) feature a unique design with an etalon smaller than the actual aperture and positioned towards the rear of the OTA. This enables us to price the 70mm telescope less than the SolarMax 60 telescope. This design creates a bandpass of <0.8 angstroms which is slightly higher than the standard for other SolarMax series telescopes.
