This telescope allows you to perform observations of the Sun’s surface in the hydrogen-alpha line and reveals filaments, flares and prominences.
With an aperture of 80 millimetres and an effective focal length of 1,400 millimetres (f/17.5), the telescope delivers sharp, full-field images of the Sun with excellent resolution. The integrated 4.3x telecentric barlow lens is optimised for transmission of the H-alpha line and ensures uniform illumination across the entire field of view.
The 13-millimetre-diameter blocking filter and the PID-controlled electronic tuning system ensure stable and precise tuning to the H-alpha wavelength. Manual fine-tuning is possible within a range of ±0.5 Å in steps of 0.1 Å, allowing you to choose between emphasising the chromosphere or the prominences. This Etalon system is based on DayStar’s highly popular QUARK filter and requires a power supply (USB 5 V, 1.5 A, Micro-B).
The two-stage 12:1 rack and pinion focuser developed by DayStar ensures smooth and precise focusing. It has a locking brake and is compatible with focusing motors such as the EAF from ZWO thanks to 6 mm and 4 mm shafts and three M4 mounting holes. The diameter of the fine focus cone is 34 mm when both knobs are removed.
The CNC-machined aluminium tube has a lockable, retractable dust cap and an integrated carrying handle that also serves as a solar finder.
