strong lineup of speakers and talks.
On Friday evening, we will again host a session for

will be Q&A time available as well as hardware on
display. The session is oriented towards beginners,
but all imagers are invited to attend and provide
tips and encouragement.

On Saturday evening, the OCA is pleased to host
a special event with
(author of Wide Field Astrophotography)
and Don Pettit (NASA
International Space Station astronaut) who will make
a joint presentation of "Amateur Astroimaging from
the International Space Station". This talk
chronicles their long-distance
collaborations in techniques which allowed Don to
do his own "amateur" imaging from the International
Space Station. Some of Don's never-before-seen
images will be presented as well as an inside view
of astronaut life. NOTE: Don Pettit's
presence is subject to NASA scheduling.
NOTE: Due to the expense and difficulty
of finding a facility with reliable
high-speed internet access for outgoing
streaming, we are unable to again provide
an option for long-distance attendees. However,
the conference will be video taped and made
available on video CD, so we encourage those
who are unable to attend in person to
watch the video and see the presentation
materials via CD's.
