In another weird twist, Canon Japan has announced the Canon 20Da, a limited edition, limited availability (Japan only) version of the EOS 20D digital SLR. Basically, the 20Da is designed for astrophotography and has the infrared filter removed from the CMOS chip, which allows the camera to peer into the Ha spectrum. The camera can also give you live preview on the rear LCD, which helps when you are trying to focus on some guidestars using your telescope mount. Who needs a Hubble when you have a 20Da?
Astrophotography is currently The Big Thing in Japan among camera geeks. Maybe we'll have some initiatives to reduce light pollution and smog.
