All SolarMax II series filters are sold in sets. The front mounted SolarMax II and rear blocking filter. Some events on the Sun,- notably active flares and coronal mass ejections (CME), are extremely fast moving. If such features occur on the disc of the Sun, their high velocity towards the observer results in their wavelength being Doppler shifted shorter than Ha. The new RichView tuning system allows the user to fine-tune the filter to adjust for these fast moving Doppler shifted events.

 

 

 

 

 

 

 

 

 

Coronado filters are used around the world by serious solar enthusiasts and professional research facilities alike. When properly and safely mounted on your high quality refractor or other suitable telescope this filter set allows observation and imaging of the amazing and ever changing surface detail and prominences on the Sun in hydrogen-alpha (Ha) light. Custom mounting will be required (adapters not included).

The patented RichView tuning assembly allows direct tuning of the primary filter etalon. No other commercially available Ha telescope can provide the tuning range and accuracy of the SolarMax II. Now you can tune for the highest contrast views of active regions, filaments and surface detail, or quickly and easily re-tune for prominences on the solar limb.

The stunning bright red views through a Coronado Ha telescope display astounding surface and limb detail especially when the Sun is in an active phase. The sun is now heading for Solar Maximum, when activity will be at its best. Don't miss out!!
