When StellarMate cannot find network coverage, it automatically switches back to HotSpot mode so that you never lose connectivity with StellarMate!

In addition to HotSpot and WiFi, StellarMate can be connected to your LAN/WAN via Ethernet.


Modern Planetarium

StellarMate is shipped with KStars, a modern feature-rich planetarium software for all platforms.

It provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep-sky objects,all 8 planets, the Sun and Moon, and thousands of comets, asteroids, supernovae, and satellites.

Hundreds of full-color catalogs, covering the whole electromagnetic spectrum from radio to gamma rays, can be overlayed directly on the sky map. It supports adjustable simulation speeds in order to view phenomena that happen over long timescales, the KStars Astrocalculator to predict conjunctions, and many common astronomical calculations.

It includes a powerful observation planner, a sky calendar tool, and an FOV editor to calculate field of view of equipment and display them. Find out interesting objects in the "What's up Tonight" tool, plot altitude vs. time graphs for any object, print high-quality sky charts, and gain access to lots of information and resources to help you explore the universe!


Equipment Profiles

Define any number of equipment profiles and load them on the go when you need to operate specific sets of equipment. Both Local and Remote profiles are supported.

Advanced scripting features designed for observatories support custom device startup procedures that allows for remote power up of equipment without any operator intervention.


Versatile FITS Viewer

KStars simple, yet powerful FITS Viewer tool is embedded directly into Ekos and can be opened separately to examine images. It supports monochrome and colors (3D Cube) FITS files in addition to bayered images. PixInsight's XISF format is fully supported along with DSLRs formats (CR2, CR3, ARW..etc)

Additionally, it supports World-Coordinate-System (WCS) that enables additional features such as equatorial grids, object detection, and GOTO to any point in the image.

View and manipulate the histogram, and load up image statistics and FITS header information.

Observation Planner

Find new targets using the Observation Planner. Use the highly-configurable wizard to find objects of interest using numerous parameters.

Download DSS images and view objects in the Altitude vs. Time tool to plan the best time for observation.

You can even simulate how the object might appear within the eye-piece or the camera's Field of View.

Find interesting objects in tonight's sky, and when you are ready, simply command your mount to go to your favorite object.


Powerful Capture Tool

Enjoy one of the most powerful image acquisition capabilities available today. You can simply capture a preview, frame an image, or record a live video stream of planets.

For more complex requirements, the highly-configurable Sequence Queue supports batch capture of images with filter wheel and rotator support. The images can be stored remotely on StellarMate, or downloaded to your computer, or both. For non-parfocal filters, you can set the relative focus filter offsets to adjust focus when switching filters. A wizard can help you to build offsets by capturing images with different filters and measuring the exact offset required automatically

Flat field captures can be automated with the Calibration Assistant. Set the desired ADU and let Ekos calculate the perfect exposure. Dark flats are automatically generated to match the flat exposures.


Video Recording

Capture video from supported astronomy cameras and many webcams.

Select a custom ROI (Region of Interest) to exactly record what you want to reduce video bandwidth and speed up FPS.

Record monochrome and color video streams in industry standard SER format.

Field Rotator Support

Directly control your rotator from Ekos, and select the desired Position Angle for your images

You can preview how a specific orientation affects your final results by adjusting the camera field-of-view (FOV) indicator in real time on the sky map.

And with the full-sky high-resolution DSS overlay, you get to see exactly how your image would appear once imaged. No more guesses!


Dark Library

Reduce noise in your captured frames by building a dark library. Select simple dark subtraction or for noisy un-cooled cameras, construct a defect map to remove unwanted hot and cold pixels

The validity of dark frames can be configured including an expiry date and the temperature threshold at which the frame is not considered valid.


Sharp AutoFocus

Get pin-point stars with the Focus module. Using Half-Flux-Radius (HFR) or FWHM calculations, StellarMate can automatically pick a focus star, subframe it to reduce download times, and adjust focus to get you as close as possible to the Critical Focus Zone.

Use Framing to inspect your images to make any necessary adjustments. If desired, lock the focus process to utilize a specific filter wheel.

Enable In-Sequence focusing to ensure you always get sharp images during the night regardless of temperature or telescope position.


Powerful Guiding Capabilities

Use the built-in Internal guider to lock onto a star and keep it bound during the imaging session. You can toggle directional control per axis, and adjust proportional gain to fine-tune guiding performance. By default, KStars uses multi-star guiding to achieve maximum performance If desired, you may opt to select PHD2 as the external guiding applications as they are fully supported in Ekos. You can monitor guiding performance and export it to a spreadsheet for advanced analysis.

Guiding pulses can be sent either via an ST4 interface, or directly to the mount if supported.


Precision Astrometry

The days of 2 or 3 stars alignment are of the past. Welcome to the world of Astrometry, where captured images are analyzed by StellarSolver, and results are used to correct the mount position to achieve highly accurate GOTOs

Offline and remote astrometry solvers are supported including ASTAP,,or Watney.

Even if Polaris is not visible, you can still use the tool to figure out the offset. Build a mount pointing model to accomplish repeatable and reliable GOTOs during each session.

Found an image you want to capture yourself? Simply load in the image in Load & Slew and Ekos shall analyze it and slews your mount to the target location so you can capture the same exact field. The camera can even rotate to match the orientation of the target within the image so you end with the exact frame!

Easy Polar Alignment

Measure and correct polar alignment errors with the highly acclaimed Polar Assistant Tool

Ekos automatically captures and solves a number of images to accurately calculate the polar alignment errors. Follow the simple guided steps and make corrections visually until you achieve a satisfactory polar alignment for your GEM.

No need to spend half an hour trying to polar align your mount when it can be done now within a couple of minutes!


Mount Modelling

Use Ekos Mount Modelling tool to train and improve your mount internal or external model. Generate all-sky target points using various options and then command your mount to begin the process.

For mounts such as EQMod, the model is updated after each sync point and once satisfied with the results, you can save your model to be used in subsequent sessions.

Other mounts store the model internally (e.g. 10-Micron) and they can be updated accordingly to achieve superior performance for unguided imaging.

Dome Slaving

Ekos supports operation of domes and roll-off roofs.

For domes, you can slave it to follow the mount as it traverses across the sky. Simply enter the required dome parameters and then let the dome track the mount motions to ensure your OTA ends up dead-center in the dome slit.

Whether the mount is tracking or performing a meridian flip, the dome driver will intelligently command motion to reach the desired position using the shortest path possible.


Analysis Insights

The Analyze Module in KStars serves as a tool for reviewing and analyzing the details of past imaging sessions, offering insights into the sequence of events without direct control over imaging processes. The module encompasses two main graphs: Timeline and Stats, which remain synchronized to display the same time interval from the Ekos session. The Timeline presents key Ekos processes, such as image capture and guiding, with color-coded indication

This feature-rich module enhances users' ability to review and learn from their imaging experiences, aiding in refining their astrophotography techniques.

Robotic Operation

Let StellarMate capture your data while awake or asleep. It covers the whole spectrum from cold startup of the observatory, target evaluation and data acquisition, to safe and secure shutdown in case of unfavorable weather conditions.

Select your target, sequence file, fill in the necessary conditions and constraints and then start the scheduler.
The scheduler can operate the dome, slew to the target, and perform autofocus, autoguide, and image acquisition in a completely robotic fashion without human intervention.
