5. Planetary (high-speed) Imaging
The Atik Titan can take up to 15 frames per second and store them in uncom- pressed 16-
bit format on a standard hard disk drive. In order to do high-speed imaging using Capture,
the following steps must be taken:-
check the
Pre
checkbox in the Exposure dialog – this enables the fast download
mode;
set a suitable exposure time in the Exposure dialog – note that high frame rates
require short exposure times;
check the
Autosave Images
checkbox in the Exposure dialog;
enter a suitable folder and file name prefix in the text box below the
Autosave Images
checkbox (or use the browse button alongside it);
select a suitable suffix scheme from the
Seq fmt.
drop-down list;
enter your desired starting sequence number in the
Seq No.
text box;
start imaging by selecting the
Camera | Loop
menu option or else by clicking
on the
Loop
toolbar item;
stop imaging by deselecting the
Camera | Loop
menu option or else by
clicking on the
Loop
toolbar item again.
Please ensure that your hard disk drive has enough space available for your
proposed observing run – in high-speed imaging mode the Titan eats up disk space
very quickly!
Performance will be improved by minimizing the number of other
processes running on the system. If the frame rate is reduced by hard disk
performance limitations, you might be able to improve it by using a RAM disk, such as
the one provided by Dataram (see http://memory.dataram.com/products-and-
services/software/ramdisk/download-ramdisk).
