WARNING
Never solve an image at or near the celestial pole (unless Ekos Polar
Alignment Assistant Tool is used). Slew at least 20 degrees away from the
celestial pole before solving the first image. Solving very close to the
poles will make your mount pointing worse so avoid it.
Alignment Settings
Before you begin the alignment process, select the desired CCD & Telescope. You
can explore astrometry.net options that are passed to the astrometry.net solver
each time an image is captured:
· CCD: Select CCD to capture from
· Exposure: Exposure duration in seconds
· Accuracy: Acceptable difference between reported telescope coordinate and
actually solved coordinate.
· Bin X: Set horizontal binning of the CCD
· Bin Y: Set vertical binning of the CCD
· Scope: Set the active telescope in case you have different Primary and Guide
scopes. FOV is re-calculated when selecting a different telescope.
· Options: Options that are passed to the astrometry.net solver. Click the edit
button to explore the options in detail.
· Solver: Select solver type (Online, Offline, Remote). The remote solver is only
available when connecting to a remote device.
By default, the solver will search all over the sky to determine the coordinates of
the captured image. This can take a lot of time; therefore, in order to speed up
the solver, you can restrict it to only search within a specified area in the sky
designated by the RA, DEC, and Radius options above.
Astrometry.net Options
Options for offline and online solvers.
Most of the options are sufficient by default. If you have astrometry.net installed
in a non-standard location, you can change the paths as necessary.
· Use Sextractor not python: This allows you to use Sextractor to make XY Lists
in order to avoid using python with astrometry.net. It vastly improves the
solver speed. This is a good option to be enabled on MacOS since they don't
