The professional research-grade Daystar Filters SolaREDi 127mm f/21 0.3? H-Alpha Solar Telescope combines a full-aperture solar filter with the same electronic tuning system used in their Quantum-series filters to produce a powerful and effective dedicated solar-viewing telescope. Tuned specifically to the 0.3? bandpass, it will show sharp details with enhanced contrast when viewing fine surface features like granules. The native wing shift that occurs on the sun will be more apparent with the 0.3?,and prominences will be very thin and fine-lined. This version of the SolaREDi is designed for professional research-grade users who require tight tolerances and improved quality. To accomplish this, Daystar improves homogeneity and on-band transmittance values across the substrate surface, so these filters require additional quality control steps, as well as additional fabrication and testing times.
The SolaREDi comes calibrated for the H-alpha wavelength at 6562.8? and using the electronic tuning system, which is accurate to 0.01?, the wavelength can be offset as much as 1.0? in either direction for Doppler shift compensation and to highlight specific areas with a digital display showing the exact tuned wavelength. The SolaREDi is equipped with a sturdy 2″ steeltrack rack-and-pinion focuser that is designed to carry heavier loads without flexing and a Vixen-style dovetail mounting ring set that makes it compatible with a wide range of mounts on the market today.
Optical Tube
Large 127mm f/21 aperture helps to reveal fine details
Long 2667mm focal length produces a high magnification potential
Achromatic doublet refractor-style optical configuration
Integrated 2-element Barlow system produces a longer effective focal length than the optical tube length
Carbon fiber optical tube construction reduces weight without sacrificing strength or stability while being resistant to expansion/contraction experienced by metal tubes when moving between extreme temperature changes
2″ steeltrack rack-and-pinion focuser can carry heavier loads, such as imaging systems, without flexing—ensuring the optical path stays straight and true
1.25″ reducer adapter to use smaller eyepieces
