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).
