Product photos of the upcoming EOS Ra have appeared. It’s very seemingly we’ll see this digital camera very shortly.
The EOS-Ra is an EOS R with a sensor modification that permits for h-Alpha wavelengths to cross by means of unimpeded by the IR reduce filter that sits in entrance of the sensor. Normally a inventory IR Cut filter that digital cameras make use of has round a 2-Three cease loss on the h-Alpha wavelength of 656.28nm.
Why is that this good for astrophotography? Atypically emission nebulae emit this wavelength, and as effectively, the Sun’s ambiance (take correct precautions in case you do this!). Letting extra of this gentle to succeed in the sensor permits for higher distinction and element in relation to nebulae and deep sky astrophotography.
Since the EOS Ra is modified to cross extra gentle of the 656nm wavelength, white steadiness and colours can be a bit off for regular pictures. You can, nonetheless, use a sizzling mirror filter that screws on the entrance of your lens to right the filtering for regular colour pictures.
