Astronomy Question Time -

Ask the Panel


CDAA Members

noaaOver the last few months we have asked members to submit astronomy questions for this event. A box and slips of paper were provided. A small group of our more knowledgeable (?!) members will attempt to answer these questions with some measure of intellegence. Whether they succeed will be up to the audience to decide.

Electronically Assisted Astronomy


Robert Ivory

noaaRobert was a member of the CDAA many years ago and following our 50th Anniversary celebration, he offered to give a presentation. Many of us know about the modern 'goto' telescopes on the market. What may not be so well known is the fact that some also have features such as image intensification technology. The view though such a telescope is enhanced electronically. I imagine that this and other features will be discussed.
