Coronado by Meade SolarMax II Solar Filter set with RichView tuning system. Includes 60mm diameter primary H-Alpha etalon filter with sub 0.7 angstrom bandwidth and Blocking Filter.
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!!
The SolarMax 60 can be used to adapt most telescopes under 3000mm to H-Alpha observing. Our mid-sized filter, SolarMax 60, provides greater resolution and opportunities for resolving detail at higher magnification than the SolarMax 40. By matching the SolarMax 60 with the appropriate Blocking Filter (see "FILTERS" for BF chart) and adaptor plate you can easily adapt most telescopes to H-Alpha viewing.
All SolarMax series filters are sold in sets. The front mounted SolarMax and rear blocking filter. Almost all telescopes will require an adaptor plate in order to attach the SolarMax,. The SolarMax includes a T-Max de-tuning 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. If the velocity is high enough, this wave length could be outside the passband of the filter and the feature would not be observable. The T-Max allows the user to de-tune the SolarMax slightly to bring such phenomena into better visibility.
SolarMax 60 can also be paired with a second SolarMax 60, second T-Max and an interface adaptor. This will reduce the bandwidth of the 60mm filter system to <0.5A and will greatly increase the contrast of the image. This addition is priced at $2,225.00. We recommend this configuration with the Coronado MaxScope due to the optimal design of this telescope allowing effective use of a double filter system. However, double stacking can be done on just about any telescope under 3000mm focal length. Not all SolarMax filters will match in this configuration, it is recommended that you send your filter to Coronado to have this work done.
