The Daystar Filters' 0.7Å bandwidth Quantum H-Alpha Bandpass Filter reveals prominences, a detail of the chromosphere projected against the blackness of space, in high contrast; and under the right conditions, surface texture. Through a 0.7Å filter prominences appear larger than when viewed with narrower bandwidth filters. The filter is installed at the rear of the OTA, rather than before the primary objective so it can be used on telescopes of virtually any aperture and easily moved between a variety of scopes.

The filter 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 and to highlight specific areas. The Quantum is outfitted with an RS-232 serial port that allows it to be connected to a computer and enables remote viewing of the wavelength display and control of the tuning. It runs on 12 VDC power and comes with a 6' power cord and a set of international outlet plugs for US, EU, UK, and Australia.
