Detailed Description
Ekos is an advanced Astrophotography tool for Linux. It is based on a modular extensible framework to perform common astrophotography tasks. This includes highly accurate GOTOs using astrometry solver, ability to measure and correct polar alignment errors , auto-focus & auto-guide capabilities, and capture of single or stack of images with filter wheel support.
Features:
A meridian flip is executed by issueing a scope motion to the target.
- Control your telescope, CCD (& DSLRs), filter wheel, focuser, guider, adaptive optics unit, and any INDI-compatible auxiliary device from Ekos.
- Extremely accurate GOTOs using astrometry.net solver (both Online and Offline solvers supported).
- Load & Slew: Load a FITS image, slew to solved coordinates, and center the mount on the exact image coordinates in order to get the same desired frame.
- Measure & Correct Polar Alignment errors using astrometry.net solver.
- Auto and manual focus modes using Half-Flux-Radius (HFR) method.
- Automated unattended meridian flip. Ekos performs post meridian flip alignment, calibration, and guiding to resume the capture session.
- Automatic focus between exposures when a user-configurable HFR limit is exceeded.
- Automatic focus between exposures when the temperature has changed a lot since last focus.
- Auto guiding with support for automatic dithering between exposures and support for Adaptive Optics devices in addition to traditional guiders.
- Powerful sequence queue for batch capture of images with optional prefixes, timestamps, filter wheel selection, and much more!
- Export and import sequence queue sets as Ekos Sequence Queue (.esq) files.
- Center the telescope anywhere in a captured FITS image or any FITS with World Coordinate System (WCS) header.
- Automatic flat field capture, just set the desired ADU and let Ekos does the rest!
- Automatic abort and resumption of exposure tasks if guiding errors exceed a user-configurable value.
- Support for dome slaving.
- Complete integration with KStars Observation Planner and SkyMap
- Integrate with all INDI native devices.
- Powerful scripting capabilities via DBus.
The primary class is Ekos::Manager. It handles startup and shutdown of local and remote INDI devices, manages and orchesterates the various Ekos modules, and provides advanced DBus interface to enable unattended scripting.

- 1.9
Essentially, the meridian flip relies upon that the mount hardware selects the pier side of the scope on the appropriate side depending whether the scope points east or west of the meridian.
While tracking a certain object a pier side change is necessary as soon as the position crosses the meridian. As soon as this is detected, the meridian flip works as follows:
- A meridian flip request is sent to Capture so that a currently running capture can be completed before the flip starts.
- Capture completes the currently running capture, stops capturing and sends a confirmation so that the flip may start.
- Now a slew command is issued to the current target (i.e. the last position where a slew has been executed). This will force the mount hardware to reconsider the pier side and slews to the same position but changing the pier side.
- As soon as the slew has been completed alignment is executed, guiding restarted and Capture informed that capturing may continue.

Capture states.
They can be divided into several stages:
- No capturing is running (
- See also
- CAPTURE_IDLE,
- CAPTURE_COMPLETE or
- CAPTURE_ABORTED)
- A capture sequence job is in preparation (
- See also
- CAPTURE_PROGRESS as state and
- CAPTURE_SETTING_TEMPERATURE,
- CAPTURE_SETTING_ROTATOR and
- CAPTURE_CHANGING_FILTER as state events signaled to
- Capture::updatePrepareState(Ekos::CaptureState))
- Calibration activities to initialize the execution of a sequence job (
- See also
- CAPTURE_DITHERING,
- CAPTURE_FOCUSING,
- CAPTURE_ALIGNING and
- CAPTURE_CALIBRATING)
- Waiting for start of capturing (
- See also
- CAPTURE_PAUSE_PLANNED,
- CAPTURE_PAUSED,
- CAPTURE_SUSPENDED and
- CAPTURE_WAITING)
- Capturing (

- CAPTURE_CAPTURING and
- CAPTURE_IMAGE_RECEIVED)
