40mm aperture narrowband Ha filter with TMax tuner and 10 mm blocking filter. Maximized for telescopes under 1000mm FL
The SolarMax 40 was designed specifically for use on short fast refractors under 1000mm focal length. Though small in size the 40mm filter is large enough to resolve fine detail in surface structure and on the Sun's limb. The SolarMax 40 will provide full disk H-Alpha views when matched with the appropriate Blocking Filter (see "FILTERS" for BF chart) on a suitable refractor.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, these are available from Coronado or through your dealer. The SolarMax includes a T-Max de-tuning device. Some events on the Sun,- notably active flares and coronal mass ejections (CMEs), 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 wavelength 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. DOUBLE STACKED SALE!! SolarMax 40 can also be paired with a second SolarMax 40, second T-Max and an interface adaptor. This will reduce the bandwidth of the 40mm filter system to <0.5 angstrom and will greatly increase the contrast of the image. This addition is priced at $1,070.00. Coronado recommends this configuration with the Coronado SolarMax Telescope 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 refractor under 1000mm 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. For MEADE ETX 60 or ETX 70 users, Coronado has designed a special blocking filter housing to work in conjunction with these telescopes. Specify Meade ETX60/70 blocking filter when ordering. Coronado will not guarantee the performance, safety, or honor the warranty of any telescope being used with a non-Coronado adaptor plate Specifications: * Type: AS1 series thermally stable with hard, non-degenerating coatings. * Bandwidth: <0.7A * Wavelength: 6562.8A (H alpha) * Aperture: 40mm For full disc image the focal length of the telescope must be less than 500mm when used with the 5mm blocking filter. The 10mm blocking filter allows for full disc image up to 1000mm focal length.
