Is This the Right Solar Telescope for You?

• You are serious about observing the Sun’s chromosphere and need a dedicated H-alpha telescope that delivers high-contrast, dynamic views of spicules, filaments, active regions, and solar flares. This isn’t a general solar scope—it’s engineered for in-depth chromosphere analysis with angstrom-level accuracy.
• You’ve outgrown entry-level solar telescopes and need a larger aperture, built-in Quantum Control, and finer wavelength stability. If you’ve struggled with wavelength drift, inconsistent contrast, or lack of solar structure detail, this is your next-level upgrade.
• You are an astrophotographer specializing in monochrome imaging and want high-contrast, high-resolution chromosphere captures. The QT127mm is optimized for monochrome CCD/CMOS cameras, ensuring crisp solar imaging with precise wavelength control.
• You need a portable yet powerful solar telescope for eclipses, research, or continuous solar activity tracking. At just 13 lbs and 29 inches, this lightweight carbon fiber OTA makes travel easy, while the fully integrated DayStar filtration means no extra filters or complicated setup.
• You want a long-term investment in high-end solar observation that eliminates the need for frequent upgrades. This fully integrated system with research-grade optics, Quantum Control, and software compatibilityensures you won’t need another chromosphere telescope for years to come.

Professional-Grade Solar Chromosphere Observation

Solar astronomy demands precision, and the DayStar SolaREDi QT127mm Chromosphere Model is engineered to deliver the most detailed views of the Sun’s chromosphere possible. With angstrom-level tuning accuracy (0.01Å), you’ll capture dynamic solar activity, from sunspots and filaments to spicules and flare regions. Unlike entry-level solar scopes, this system is fully integrated—no additional filters, etalons, or complex setups required.

For serious solar observers and astrophotographers, this telescope features a custom-coated 127mm doublet achromat, optimized specifically for Hydrogen Alpha (6562.8Å) imaging of the chromosphere. The built-in Quantum Control system ensures stable wavelength tuning, eliminating frustrating drift caused by temperature changes. No more guesswork—just sharp, high-contrast chromosphere imaging every time.

If you’ve struggled with bulky, complex solar setups, you’ll appreciate the compact 29-inch carbon fiber design. Weighing only 13 lbs, it’s portable enough for traveling to eclipses, research sites, or continuous chromosphere tracking locations. The 2" steeltrack rack-and-pinion focuser provides smooth, rock-solid stability, even when using heavy monochrome CCD cameras.

Unlike many solar scopes that require external power solutions, the QT127mm runs on low-power 12VDC (1.5W max), making it compatible with portable 12VDC power sources for flexible field use. No more scrambling for AC outlets—just plug in and start tracking solar activity.

For best results, DayStar does not recommend imaging with a DSLR or color CCD camera. Hydrogen Alpha imaging is best captured using a monochrome CCD or CMOS sensor, ensuring maximum contrast and resolution.

This is more than just a telescope—it’s a precision-engineered instrument built for serious chromosphere observation. If your goal is to study and capture detailed solar features with maximum clarity, the SolaREDi QT127mm Chromosphere Model is the ultimate tool for the job.
