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 Daystar Filters SoliRedi 127mm f/21 H-Alpha Solar Telescope combines a full-aperture solar filter and 32mm blocking filter, with the same electronic tuning system used in their Quantum-series filters, to produce a dedicated solar-viewing telescope. Tuned specifically to the 0.4Å to specifically improve solar surface contrast and fine chromosphere details as well as to generally study the photosheric, chromospheric, prominence and atmospheric areas of the sun.

This version of the SoliRedi comes calibrated for the H-alpha wavelength at 6562.8Å and using the electronic tuning system, which is accurate to 0.1Å, the wavelength can be offset as much as 1.0Å in either direction for Doppler shift compensation to highlight specific areas with a digital display showing the exact tuned wavelength. The SoliRedi comes equipped with a 2" Crayford-style focuser, and Vixen-style dovetail mounting ring set to be used on compatible mount heads.

Optical Tube
  • 127mm aperture
  • f/21 focal ratio
  • 2667mm focal length
  • Doublet refractor style-optical configuration
  • Fully multi-coated optics
  • Integrated 2-element Barlow system produces a longer effective focal length than the optical tube length
  • 2" Crayford-style focuser allows for precision focusing without backlash
  • 1.25" reducer adapter to use smaller eyepieces
Solar Filter
  • Permanent solar-viewing filter calibrated for the Hydrogen-alpha wavelength at 6562.8Å
  • Tuned specifically for 0.4Å bandwidth to improve solar surface contrast and fine chromosphere details
  • 32mm clear aperture blocking filter
Tuning System
  • Precision electronic tuning system
  • Digital display shows tuning
  • Accurate to 0.1Å 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, requires mount and tripod for proper use
  • Includes mounting ring set with Vixen-style dovetail plate
