Congratulations on the purchase of the Omegon® MiniTrack LX3. This mechanical mount will give you hours of fun. It is the ideal companion for the beginner, intermediate and advanced amateur who is looking for a compact and carry-on mount solution. It’s simple design and mechanical quality makes the MiniTrack LX3 a unique tool for wide-field astrophotography.

What’s included?

  • A- Polar finderscope;
  • B- Hex key.

How does the Minitrack LX3 mount work?

The Minitrack LX3 “follows” i.e. tracks the apparent movement of the night sky – please notice the two articles covered in this instruction manual are designed to be used in the northern hemisphere.
The sky “rotates” roughly around Polaris – the northern Star. So in order to have a successful tracking the mount must point to Polaris. This is called setting the mount in station. The mount sits on a tripod head allowing a certain degree of inclination. Usually the inclination corresponds to the latitude of the location. Besides that, a ball head is required so that the camera can be easily pointed to the desired object. Then wind-up the built-in timer and you are ready to go!

How to set the Minitrack LX3?

  1. Start by installing the polar finderscope  holder (Side A part 1) using the supplier Hex key as shown.
  2. The Minitrack is compatible with any ¼” tripod plate (#9 Side B). Set the MiniTrack to the tripod’s plate (not supplied) as shown. Make sure that the MiniTrack is set so the inclination can be adjusted.
  3. Make sure the MiniTrack is parallel to the adapter base. This is important because the inclination needs to be fine-tuned to set the mount in station.
  4. We recommend using a ball-head to operate the Minitrack. From the factory the MiniTrack already has a pre-installed 3/8” thread.
  5. The ball-head must be securely fixed. Make sure to tighten it well. All the weight from the camera will rest on the ball-head. Besides that, a well-fixed ball-head ensures that there will be no slippage during long-exposures. At this point, it is important that the ball-head knobs are also tight. This prevents movement when installing the camera.

    What is slippage?
    Depending on the camera angle the setup’s centre-of-mass may be against or for the ball-head’s thread pitch. This can cause the ball head to slip. To avoid it, the ball-head must be securely fixed. The built-in rubber mate helps reducing this problem.
  6. Install the tripod plate (included only with the ball-head version) to the camera. Make sure the adapter is square to the camera base and well tighten.
  7. Set the camera (with the adapter) to the ball’s-head base. Make sure to tighten it well. Please notice that the ball-head has two additional knobs. One fixes the ball’s-head position in azimuth (360 deg) while the other fixes the ball’s-head pointing direction (in altitude). These two degrees of orientation allows the user to point to any desired object in the sky. Make sure both are well tighten before installing the camera. Release the knobs – just slightly – to allow pointing the camera to different directions.
  8. Point the mount to the Polaris. It is not important to be exactly aligned with the Polaris– a rough alignment is fine. Upon installing the supplied polar finderscope (A) we will look in more detail on how to have the star in the centre of the polar finderscope (A) field of view.

    How to identify Polaris?
    Polaris is not the brightest star on the sky but still easy to identify. Look up to north and try to find the Big Dipper (constellation). This is a very recognisable constellation. Polaris is about six times the distance and direction of two of it’s brightest stars – Merak and Duhbe.
  9. To align the mount to Polaris with more precision slide the plastic sleeve to the finderscope and “click” it to the holder.

    Please note: Depending on the supplied Polar finderscope’s version the sleeve may not be required. If the Polar finderscope has de adequate diameter to directly fit to the Polar finderscope holder (larger than the sleeve) do not use the sleeve. Use the sleeve only when required.
  10. Peek through the polar finderscope (A) and centre Polaris in the visual field. Turn the tripod’s fine-adjustment levelers to do so. Please read the following section for more details on how to correctly use the MiniTrack LX and the importance of correct balance.

Balancing the MiniTrack on the East hemisphere.

The built-in timer pushes the photo setup to track the night sky. If the setup’s centre of mass is slightly off to the West side of the hemisphere, the generated arm-moment helps the timer to track the objects, this is good. However, the opposite, i.e. if the setup is more off balanced to east side it may happen that the timer will have difficulties to push and track conveniently. For that reason the built-in spring system acts as a counterweight and gives an extra help to the timer by adding additional push force.

How to determine if timer is not able to push the setup?
Listen to the timer ticking without any load. Compare that sound to when the setup is assembled. Is there a huge sound difference? – i.e. the timer is not as loud as it should be – then the spring tension must be adjusted.

Tensioning the spring.

For setups, slightly off-balance use the first positions as shown (image to the left). You can feel that the spring is not under a lot of tension. Use the spring at its highest tension only for heavy setups and strong unbalance. See below how to choose the spring’s position.

Please avoid unnecessary spring tension as this might alter the timer’s clock tracking rate!

Pointing East.

When the weight of the camera setup tends to rotate the ball-head in an anticlockwise direction, the spring should be tensioned to one of the numbered teeth, based on how strong the imbalance is. By tensioning the spring in position 5 (worst case scenario) a weight of up to 3kg can be balanced – i.e. pointing to the Zenith with the camera body towards the east in respect to the ball-head.

Pointing South.

The spring can be completely disengaged (position “0”) or let it work at idle (position”1”).

Pointing West.

Aiming towards West, especially if there is a strong imbalance, it could happen that the timer “accelerates” because of the load in favour of the movement. If that is the case, use the spring retainer’s part marked with a minus sign “-“. One can choose from position 1 to 3 to reduce the tracking speed.

Calculating maximum tracking time.

The MiniTrack LX3 is designed to carry setups up to 3 kg and track during 60min. This is important to know because setups exceeding this limit may considerably reduce the tracking quality and total tracking time. Something to notice is the objective’s focal length. Wide-field objectives (low focal length) allow for more exposure time. Rule of thumb: one can calculate the tracking time without star trailing by using the following formula:

Time (min) = 100 / Objective focal length (mm)

Objective focal length Maximum recommended exposure
24mm 4 minutes 10sec
50mm 2 minutes
60mm 1min 40sec
100mm 1 min


Camera + objective = 2.8 kg; Objective’s focal length 50mm.
This is within the specifications of the mount. We should expect to achieve 100 / 50mm = 2 minutes of tracking without any issues.
What if the weight exceeds the carrying capacity or if we use more exposure time than the recommended?
Then we will see some star trailing becoming more evident. It may be necessary to try different exposure times to better judge which one better fit each setup.


For more information please refer to on-line content such as videos. There is also a very active facebook group (in Italian) about the MiniTrack LX with hundreds of followers and many contributions. The inventor, Mr. Cristian Fattinnanzi is also a member of this group and would gladly give some information and tips on how to use this mount. Main language is however Italian.
