The StellarMate Plus Manual
266 / 341
The Debian packages are suitable for any Debian-based distribution (Ubuntu,
Mint, etc.). If you downloaded the Debian Packages above for your FOV range,
you can install them from your favorite package manager, or via the following
command:
sudo dpkg -i astrometry-data-*.deb
On the other hand, if you downloaded the FITS index files directly, copy them
to /usr/share/astrometry directory.
Note
It is recommended to use a download manager as such DownThemAll! for Firefox
to download the Debian packages as browsers' built-in download manager may
have problems with download large packages.
How to Use?
Ekos Align Module offers multiple functions to aid you in achieving accurate
GOTOs. Start with your mount in home position with the telescope tube looking
directly at the celestial pole. For users in Northern Hemisphere, point the
telescope as close as possible to Polaris. It is not necessary to perform 2 or 3
star alignments, but it can be useful for some mount types. Make sure your
camera is focused and stars are resolved.
· Capture & Solve: Capture an image and determine what region in the sky the
telescope is exactly looking at. The astrometry results include the equatorial
coordinates (RA & DEC) of the center of the captured image in addition to
pixel scale and field rotation. Depending on the Solver Action settings, the
results can be used to Sync the mount or Sync and then Slew to the target
location. For example, suppose you slewed the mount to Vega then
used Capture & Solve. If the actual telescope location is different from Vega, it
will be first synced to the solved coordinate and then Ekos shall command the
mount to slew to Vega. After slew is complete, the Alignment module will
repeat Capture & Solve process again until the error between reported and
actual position falls below the accuracy thresholds (30 arcseconds by
default).
· Load & Slew: Load a FITS or JPEG file, solve it, and then slew to it.
· Polar Alignment Assistant: A simple tool to aid in polar alignment of German
Equatorial Mounts.
· Legacy Polar Alignment Tool: Measure polar alignment error when a view of
the celestial pole (e.g. Polaris for Northern Hemisphere) is not available.
