This is the filter for imaging in moonlight or light pollution with a colour CMOS camera - or even in dark-sky conditions if you want total isolation and control over your channels, narrowband-style.
Altair DualBand 6nm Filter Features:
Capture the two main emission nebulae bands at the same time, whilst suppressing light pollution, moonlight, and airglow.
Acquire more data in less time, opening up your imaging window, even into the summer months when it isn't quite dark.
If you have the 6nm Ha/Sii Ultra filter and the Sii/Ha version, you can capture twice the Oiii data in each imaging session and combine them for true SHO Hubble style imaging with a colour camera!
Extremely steep bandpass yields maximum contrast in extreme light pollution: 6nm FHWM centred on 500.7nm Oiii wavelength, and 5.5nm FHWM centred on the 656.28nm Ha wavelength.
No halos. We have not had any reports of halos caused by this filter in testing, and we don't expect any with our new V2 hard coating technology.
The Altair Dichroic Solar Energy Rejection Filter or D-ERF protects your telescope and solar imaging equipment from excessive heat build-up when solar imaging or observing with your Daystar Hydrogen Alpha Quark, or other Hydrogen Alpha Etalon filters.
