3 Imaging Features
3 Professional Edition supports imaging. Plan imaging sessions and
optimize imaging in real time. The focus of SkyTools
imaging session planning is on helping you make the best imaging
choices. Optimum sub-exposure times are computed for image stacking,
final signal-to-noise ratio is estimated, the number of stacked
images required to obtain the desired signal-to-noise is
computed, and the optimum time period to observe your object is
The imaging quality
for a selected object is drawn as a function of time below (blue
line). The relative quality depends on both the conditions and
the object. Readily compare different objects, filters,
sub-exposure times, nights, cameras, telescopes, locations, etc.

it comes time to observe, the Real Time tool has an imaging
mode which can help you make informed choices as you work.
The Imaging Context Viewer helps to identify fields and aid in
image placement. It can also be used to point a connected
telescope simply by dragging the camera rectangle to a new
first of its kind Imaging Session Planner -- supports
deep sky, planetary, lunar and solar imaging for
astronomical CCDs, digital cameras, and video/web cams. Know
with certainty when each object is best imaged. When

calculations and to explore the possibilities.

Context Viewer -- an
innovative side window for the Atlas that displays a
simulated image for your camera and telescope.
This tool is perfect for locating the correct field; readily
compare a short exposure to the simulated image. Drag
the imaging FOV anywhere on the chart to test placement, and
if a telescope is connected the telescope will follow!
Stellar Database -- stars to 20th magnitude over the
positions for all known asteroids -- these can be
downloaded from within SkyTools to aid in identification
of moving objects.
Tracking of Asteroids and Comets -- follow a comet or
asteroid during your exposures (with mounts capable of this
Planetary imaging time without blurring--
computes the maximum time over which the Sun or a planet can
be imaged to avoid blurring due to the rotation of the
object in the final stacked image.
Download Selections -- DSS, SDSS, IR, H-alpha, and 2MASS
images are available for download and display in the chart
backgrounds. These images can be used in the Atlas or
in the Context Viewer to aid in camera placement.
Projection Calculator -- computes the optimum separation
between the eyepiece and camera and computes the final
image scale for any given separation.
Star Pair Resolution and Image Scale
Alignment Tool -- takes the guesswork out of aligning
