DayStar Filters SolaREDi 127mm f/21 0.3Å H-Alpha Solar Telescope (PE Grade, OTA Only)

BH #DA3SR127PE • MFR #.3SR127PE
DayStar Filters SolaREDi 127mm f/21 0.3Å H-Alpha Solar Telescope (PE Grade, OTA Only)
Key Features
  • Integrated Hydrogen-Alpha Solar Filter
  • Engineered for Professional Research Use
  • 127mm Refractor Solar Scope
  • 2667mm Focal Length, f/21 Focal Ratio
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.

SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

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

Solar Filter

  • Designed for professional research-grade use
  • Improved homogeneity and on-band transmittance values across the substrate surface over standard-grade models
  • Permanent solar-viewing filter calibrated for the Hydrogen-alpha wavelength at 6562.8Å
  • Tuned specifically for the narrow 0.3Å bandpass, it will show sharp details with enhanced contrast on surface features like granules
  • Prominences will be very thin and fine-lined
  • Precision electronic tuning system
  • Digital display shows tuning
  • Accurate to 0.01Å in center wavelength
  • Enables wavelength to be offset as much as 1.0Å in either direction for Doppler shift compensation and to highlight specific areas
  • Runs on 12 VDC power with included AC adapter

Mounting

  • OTA only—mount and tripod required for proper use
  • Includes mounting ring set with Vixen-style dovetail plate
  • 13.6-pound weight
