Coronado SolarMax II 60 H-Alpha Filter with BF15 and RichView Tuner
This SolarMax II 60 comes with a BF-15 blocking filter, a secondary interference filter which mounts at the eyepiece end of the telescope. You cannot use the individual units (either the blocking filter or the front-mounted SolarMax's) separately. The BF15 is mounted inside the body of a 1-1/4" right-angle diagonal. It is optimized to provide a full disc image on telescopes with a focal length of up to 1500mm.
About the RichView Tuner...
Some events on the Sun, notably active flares and coronal mass ejections (CME's) 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 RichView allows the user to de-tune the SolarMax II slightly to bring such phenomena into better visibility. The RichView fits between the SolarMax II and it's adapter plate, sold separately. A simple rotary wheel movement accomplishes the tilt necessary to move the passband of the filter. Because of the filter's position at the front end of the telescope, this does not compromise the performance of the filter nor limit the Ha field of view as is the case with rear-mounted filters.
Below you'll find a list of explanations regarding important accessories that may be required for this product.
- An adapter plate is required to attach this filter to your telescope. Coronado is no longer producing these adapters however, Ashley Precision Parts is providing custom adapters for our customers. Please provide the telescope you will be adapting to, the outer diameter and whether you need a slip fit or threaded plate, in the comments section during check out. If you have any questions regarding these plates, please feel free to email our internet sales team for more information.
