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 0.6Å bandpass, it offers middle-of-the-line viewing capability that allows you to observe both solar surface contrast as well as prominences, and is an ideal choice for those who want to view a variety of solar structures and features.

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 0.01Å, the wavelength can be offset as much as 1.0Å in either direction for Doppler shift compensation and 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.
