DayStar Filters

DayStar Filters redesigned their standard-grade SolaREDi QT 127mm f/21 Chromosphere H-Alpha Solar Telescope to make it lighter and shorter for easier handling and use on smaller mounts. It 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. This version of the solar scope allows you to study the rich details of the sun's chromosphere. The chromosphere's surface structure behaves differently in active regions than quiet areas where magnetic field lines are stronger, so viewing this portion of the sun provides a constantly changing observational experience. DayStar outfitted the SolaREDi with a standard filter system and is ideal for general-purpose amateur and limited research use. To protect this delicate instrument, it comes in a Pelican Storm Case with a custom-cut foam insert.Optical Tube Large 127mm f/21 aperture helps to reveal fine detailsLong 2667mm focal length produces a high magnification potentialAchromatic doublet refractor-style optical configuration is reliable, easy to maintain, and does not require periodic collimationIntegrated 2-element Barlow system produces a longer effective focal length than the optical tube lengthCarbon 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 changes2" steeltrack rack-and-pinion focuser can carry heavier loads, such as imaging systems, without flexing ensuring the optical path stays straight and trueFocus lock mechanism prevents focus shift to ensure consistent images1.25" reducer adapter to use smaller eyepiecesSolar Filter Standard (SE) grade filter system is ideal for amateur and limited research usePermanent solar-viewing filter calibrated for the Hydrogen-alpha wavelength at 6562.8 Tuned for viewing details of the sun's chromosphere, with a bandpass typically between 0.5 and 0.3 The chromosphere can be thought of as a shell of gas around the sun's photosphere and is always moving and changingThe structure of the chromosphere behaves differently in active regions where magnetic field lines are strongerThe chromosphere is governed by magnetic forces and thought to be tied to the photospherePrecision electronic tuning systemDigital display shows tuningAccurate to 0.01 in center wavelengthEnables wavelength to be offset as much as 1.0 in either direction for Doppler shift compensation and to highlight specific areasRuns on 12 VDC power with included adapter or user-supplied battery bankMounting OTA only mount and tripod required for proper useIncludes mounting ring set with Vixen-style dovetail plateLength of 29 inches (31.1 with dew shield)Weight of 13 pounds
