One of the most unique features of
Star Adventurer 2i
is its ability to create time-lapse
videos of celestial vistas. This feature combines
Star Adventurer 2i
’s astrophotography
functions with its time-lapse functions giving you a powerful tool to create stunning and
unique time-lapse videos. Note that to obtain astronomical time-lapse videos you must polar
align
Star Adventurer 2i
as described above. Below are the parameters you can set along
with their explanations for producing astronomical time-lapse videos
Exposure (Sec): Exposure
should be set to a value
that is sufficiently long to record detail in the night time
sky, which is typically longer than 30 seconds. Be sure
that your camera is attached to
Star Adventurer 2i
via
the
SNAP
control cable, then set your exposure time
in this field. Be sure to set your camera to BULB mode,
otherwise your shutter will not stay open. It will close
according to whatever shutter speed is selected on
your camera.
Video Time Span (Hr): Video Time Span
refers to the
amount of real time that will elapse from the start to the
end of the recording.
Video Time Span
is affected by
Exposure, Photos, Video Length
and
Frame Rate
,
and will be calculated for you. However, you can also
directly set a value for
Video Time Span
. For instance,
if you want to follow the Moon for 5 hours to record the
stages of a lunar eclipse, you could set
Video Time
Span
to 5. Set the length of your desired time-lapse
video in
Video Length
and the appropriate frames per
second (fps) in
Frame Rate
. Other related parameters
will then be calculated for you.
Video Length (Sec):
Set this parameter to the desired
length in seconds of your finished time-lapse video.
You can set this parameter directly, or you can allow it
to be calculated for you based on the values of other
parameters.
Frame Rate:
Select NTSC (30 fps) or PAL (25 fps)
according to the video standards for your location. You
can further adjust the playback speed of your video in
your video editing software.
Photos:
Enter the number of photos you wish to make
up your video. It is usually easier to let this field be
calculated based on settings for other parameters.
