Advances in Astro-Imaging
Convenor: Fred Vanderhaven, ASNSW
Schedule: To be advised
This round-table session will cover two exciting new areas in astro-imaging:
- The use of narrow-band filters, such as H-alpha, SII and OIII, allows extracting detailed structure from deep-sky objects that does not appear in conventional wide-band imaging. The resulting images offer a totally new view of familiar celestial objects. As well, narrow-band imaging is much less effected by suburban light pollution, so astro-imagers don’t have to move to pristine dark skies to get excellent images.
- Many amateur telescopes today are fully computer controlled. Once connected to the Internet, imagers from around the world can capture data that is difficult or impossible to obtain otherwise. Fred is a member of such a network: GRAS — Global Rent-A-Scope.
In this session, Fred will explain the details of narrow-band imaging, and his involvement in the GRAS network. The session will also include a demonstration (weather permitting) of the GRAS network to acquire an image live from the US.
