Quad Band Filter o
I am considering testing the Radian Telescopes Triad Ultra Quad-Band Narrowband Filter on my DSLR
Will it be possible to extract the 4 channels, Hydrogen-beta, Oxygen III, Hydrogen-alpha and Sulfur II separately? In order to then create an image in Hubble Palette, for example.
With a DSLR you can't separate all those bands with a quad band filter, APP can extract Ha and OIII from the data and HB and SII will then be in the mix of those signals. If you search the forum for "quad band filter" you can find a lot of discussions about this specifically. You can have filters for SII alone etc and then you can play around with that data (given your DSLR is modified as otherwise a lot of signal will be filtered out by the filters already on the DSLR sensor).
- Ok thanks. My camera is modified... so could I then extract Ha and OIII from a shot with a dual band filter (e.g. Optolong Extreme) and take a second shot with an SII filter and then combine that together?
