Astrophotography using conventional film has been the mainstream practice among local astrophotographers since the inception of the HKAS. With the advent of digital imaging, however, many of them have begun to experiment with this new recording medium.
In 1999 a digital astrophotography group, led by HKAS vice president Chi-Hung Yeung, was formed to promote the use of digital-imaging and -processing techniques.
The HKNEAC operates the largest telescope in Hong Kong--a computerized DFM 0.5-meter (20-inch) Ritchey-Chretien reflector--which is used mainly for education programs conducted jointly by the HKAS and the center for high-school students and teachers.
The project's coordinator, HKAS president Kam-Cheung Leung, regards this as a good opportunity for collaboration between amateur and professional astronomers.
