The DayStar SolaREDi 127 is a high quality carbon fibre achromatic doublet refractor specifically designed for the Hydrogen-alpha wavelength. It contains either an SE-grade Quantum Chromosphere or Prominence H-alpha filter specifically adapted to this particular telescope, or PE-grade specific bandpass from 0.2 - 0.8Å.
- The Chromosphere version features a bandpass between 0.5 - 0.3Å (depending on your telescope's f-ratio), making it the perfect choice for viewing surface detail, although prominences will still be visible.
- The Prominence version has a bandpass of 0.9 - 0.6Å, which will deliver bright, high-contrast views of prominences against a jet black sky.
Unlike the popular Quark filters, the Quantum filter features a digital readout and precision tuning control accurate to 0.01Å in center wavelength.
