                                                                                       Solar Blocking Filters for SolarMax II 60  Choices:


The Coronado BF5 solar blocking filter will deliver a Full Disk image of the Sun in solar telescopes with a Focal Length of 500mm or less.  The 5mm aperture is quite sufficient for solar Viewing.   # SMT60-5,   SMT60DS-5  (Double Stack)


The Coronado BF10 blocking filter  provides a Full Disk image of the Sun in solar scopes with a Focal Length of 1000mm or below. The 10mm aperture is a great choice for Visual use or when Imaging with a DSLR.   # SMT60-10,   SMT60DS-10  (Double Stack)


The Coronado BF15 Blocking Filter allows a sharp Full Disk image in solar scopes with up to 1500mm Focal Length. 15mm of aperture provides ample light for Imaging with large chip DSLR and CCD cameras.   # SMT60-15,   SMT60DS-15  (Double Stack)

                            These Blocking Filters MUST be paired with a SolarMax II and/or T-Max Etalon Hydrogen Alpha Filter ! 

Built to exacting standards, the Coronado Solar Max II 60mm series of Dedicated Solar telescopes not only provides the user with a telescope with excellent portability but the ideal 60mm aperture greatly increases the resolution of detail on the surface and on the limb (the outermost edge of the disc). The SolarMax II 60 features the RichView tuning method which allows very precise direct adjustment of the primary etalon filter by a lever (shown right) in the side of the scope body which mechanically tilts the filter's bandpass of the H-alpha line, normally centered at 656.28 nm. This adjustment allows for higher contrast views of Doppler-shifted solar activity, such as moving flares. 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 H-apha. The new RichView tuning system allows the user to fine-tune the filter to adjust for these fast moving Doppler shifted events. Additionally, you can tune for the highest contrast views of active regions, filaments, and other surface detail, or the system can be quickly and easily re-tuned for prominences on the solar limb.

The RichView mechanical tuning section sits between a two-piece Solar Filter set (left) and the objective lens.  *The two-pieces of the solar filter set  MUST be used together to prevent serious and potentially irreparable damage to the observers eyes!  At the heart of the SolarMax II viewing system is a primary 60mm tunable etalon filter with a <0.7 Angstrom passband centered on the 656.28nm H-Alpha line.  The companion component is a Blocking (Interference) Filter in a right angle star diagonal.  The Coronado Blocking Filters are thermally stable (they bleed off excess heat) so there is no drifting off the H-Alpha line as the filter heats up during use. The clear aperture of the blocking filter portion of this H-alpha system is designed to provide full disk single eyepiece views of the Sun for Visual and/or Imaging use. 

A Coronado Cemax (Contrast Enhanced) 25mm 1.25” eyepiece is standard equipment, providing a magnification of 16x and a 3.25° field. Cemax eyepieces use an anti-reflection multicoating formula on every surface and have been optimized for the highest possible contrast during solar viewing of subtle prominence and surface detail.  20mm of eye relief and a 52° AFOV complete this eyepiece specifically designed for H-Alpha solar viewing.

        We live in the extended atmosphere of a magnetic variable star that drives our solar system and sustains life on Earth.

SOLAR MAXIMUM:  Forecasters say Solar Max is due in the year 2013.  When it arrives, the peak of the 11-year sunspot cycle will bring more solar flares, more coronal mass ejections, more geomagnetic storms and more auroras than we have experienced in quite some time.  In mid July, 2012  a coronal mass ejection or "CME" crashed into Earth's magnetic field and triggered the most sustained display of auroras in years.  For more than 36 hours, magnetic storms circled Earth's poles.  The source of the CME was giant sunspot AR1520, a seething nest of tangled magnetism more than 15 times wider than Earth itself.  On July 12th, the sunspot's magnetic field erupted, producing an X-class solar flare and hurling a billion tons of electrified plasma toward our planet.
