WARNING

!

Looking at the Sun can be very dangerous unless the proper precautions are taken and 

specialized solar viewing equipment, like Coronado Solar filters and telescopes are used.  Never 

look at the Sun directly with your eyes.  When using Coronado filters on a telescope not designed 

specifically for solar viewing, be sure to block all non-filtered optical components such as 

viewfinders to prevent the suns light from passing through.  An inadvertent glance thought an unfiltered or improperly 

filtered optical system can cause immediate and permanent damage to the eye.  Never allow unattended children to 

operate or be near a solar telescope system.
Coronado SolarMax hydrogen-alpha telescopes and filters are designed and tested to provide safe viewing of the 

Sun.  These systems consist of two critical parts:  The etalon filter that may be mounted at the front of the telescope or 

internally inside the telescope tube and the blocking filter that is mounted at the back of the telescope.  Both of these 

components must be properly installed to provide safe solar viewing.  Most Coronado blocking filters (BF filters) are 

installed in a special diagonal that mounts at the rear of the telescope and holds the eyepiece.  Do not replace this 

diagonal with any other diagonal.  Without the blocking filter inside the dedicated Coronado diagonal, light from the 

sun is not fully filtered and looking through the system can result in eye damage even with a quick glance.
