WARNING!
Meade Instruments has night and day covered for the amateur astronomer. Meade is the leader in night 
time astronomy with the most advanced optical, mechanical and electronic systems for viewing the night 
sky. With Coronado and the development of the SolarMax II, Meade is the clear leader in solar day time 
observing as well. Whether you are imaging deep sky objects with your Meade astronomical telescope and 
DSI or gazing at our nearest star through a Coronado SolarMax telescope, keep an eye on the Meade team 
to provide you with the most technologically advanced and innovative product to enhance your enjoyment of 
astronomy. No matter where, or what time of day your interest in astronomy calls to you, 
we will be there with you.
Night and Day, we’ve got you covered.
Looking at the Sun can be very dangerous unless the proper precautions are taken and 
specialized solar viewing equipment, like Coronado Solar fi lters and telescopes are used. 
Never look at the Sun directly with your eyes. When using Coronado fi lters on a telescope 
not designed specifi cally for solar viewing, be sure to block all non-fi ltered optical 
components such as viewfi nders to prevent the suns light from passing through. An inadvertent glance 
thought an unfi ltered or improperly fi ltered 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 and SolarMax II hydrogen-alpha telescopes and fi lters are designed and tested to 
provide safe viewing of the Sun. These systems consist of two critical parts: The etalon fi lter that may be 
mounted at the front of the telescope or internally inside the telescope tube and the blocking fi lter 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 fi lters (BF fi lters) 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 fi lter inside the dedicated Coronado diagonal, light from the sun is not fully fi ltered 
and looking through the system can result eye damage even with a quick glance.
