MAIN MENU
You can access the main menu by pressing and holding the circle button for 2 seconds.

Move with the up or down arrow button and select your choice by clicking the right arrow.

GOTO
Users can access several popular celestial object catalogs stored in the NYX Hand Controller and use it to control the telescope mount, enabling precise location of specific objects within the catalogs

Warning : Never Look at the Sun Through a Telescope Looking at the sun directly through a telescope can cause permanent eye damage or blindness. Always use a proper solar filter that covers the front of the telescope if you intend to observe the sun. Never use an eyepiece filter for solar observation, as it can crack under intense heat. Ensure that anyone using the telescope is aware of this danger. Safety first!

Available set of catalogs

• Stars

  • Bright Stars Bright stars are catalogued by their asterism name and star catalog designation, for example, A Cygnus [Albireo].

  • Struve SST
    The Struve Double Star catalog includes information such as the positions and separations of double stars, as well as their magnitudes and observational details.

  • Carbon Stars

  • This catalog focuses on carbon stars within our Milky Way galaxy, providing detailed information about their positions, magnitudes, spectral types, and other relevant data.

• Deep Sky Objects

  • Messier
  • Caldwell
  • Hershel 400
  • Collider
  • NGC
  • IC
  • Solar System Planets, Moon and Sun
  • Filter Catalogs
  • Coordinates
  • Home

Note: When you select a target, the mount will begin slewing towards it. To cancel slewing, press any arrow button. The display will show “Slew to target aborted”.

SYNC
Select this menu to sync the telescope to a known target. The catalog available is the same as before, but in this option, you sync the telescope to the selected target. Select the target and when ready press the left arrow button. The mount position will be synced with the target.
HOME

• Goto Home
• Reset Home

Select Goto Home to move the mount to the home position in both axes. Reset Home resets the current position of both axes to zero, essentially telling the mount that its current position is the home position.
Note: Reset Home should not be used as it resets the actual position of both axes to zero. You need to reset axes in case your mount has lots its position (e.g axes collapse due to very high load). Before using “Reset Home,” ensure that both axes are already manually moved to the home position (NCP or SCP in case of sidereal mode) to avoid incorrect positioning.
ALIGN
Star alignment ensures that the mount operates effectively by establishing correct polar alignment (in EQ mode), enabling accurate tracking of celestial objects, reducing field rotation effects, and improving overall pointing accuracy for observational and imaging purposes. You can align up to 9 stars.

• 1-Star Align
• 2-Star Align
• 3-Star Align
• 4-Star Align
• 5-Star Align
• 6-Star Align
• 7-Star Align
• 8-Star Align
• 9-Star Align
•  Select “Align” and choose the number of stars you wish to use for alignment. The mount will guide you to each star sequentially. The hand control will generate a list of the bright stars within the selected horizontal region and prompt you to select a star from this list. The display will also indicate the star number for alignment, such as Star #1.
• After selection, mount will start slewing to the star.
• When the mount reaches the target, use the arrow keys to center the star in your field of view as precisely as possible. Once centered, press the circle button to proceed to the next star and repeat the process.
• After aligning all selected stars, the mount will create an alignment model based on your inputs.

Cancel Alignment
To cancel alignment, press the left button multiple times until you see “Alignment Aborted” on the display. Also, while the mount is slewing during alignment, you can press any arrow button key to stop the mount. You have the option to display the alignment model created from your inputs or to completely clear the model and redo the star alignment.

Improving Alignment
Alignment accuracy can also be influenced by the selection of alignment stars. Choosing suitable alignment stars that are well-spaced and easily identifiable can enhance the overall accuracy of the alignment process.
We recommend performing a minimum 3-star alignment for good pointing accuracy, even if there is cone error in the telescope-mount system, especially beneficial for visual observation where precise polar alignment is not necessary. When choosing alignment stars:

• Spread the 3 alignment stars on both sides of the meridian.
• For alignment stars on the same side of the meridian, ensure their Right Ascension (R.A.) deviation is greater than 3 hours, and the absolute difference in their declinations is between 10 to 30 degrees (10°< |Dec1 – Dec2| < 30°).
• If cone error is suspected or uncertain, avoid selecting alignment stars with small declinations (close to the celestial equator).

For Alt-Azimuth mode

• Align the altitude of the two alignment stars between 15 and 60 degrees, with an altitude deviation between 10 and 30 degrees.
• The azimuth deviation of the two alignment stars can range between 45 and 135 degrees, ideally close to 90 degrees for optimal alignment accuracy.

During the alignment process, it’s crucial to center the alignment stars precisely at the center of the telescope’s eyepiece field of view (FOV). Using a reticle eyepiece is recommended for accurate alignment. If a reticle eyepiece is not available, using an eyepiece with a shorter focal length can yield a smaller FOV, making it easier to center the star. Another technique is to slightly defocus the telescope to create a larger star disk in the FOV, which is easier to center than a sharp star. Throughout the alignment process, avoid changing or rotating the eyepiece and diagonal mirror to maintain stability and accuracy.

Polar Alignment

• Polar Align

Polar aligning an equatorial mount is crucial for several reasons. Polar alignment ensures that the mount’s right ascension (RA) axis is aligned with the Earth’s rotational axis. This alignment allows the mount to track celestial objects accurately across the sky with minimal adjustments, maintaining the object’s position in the field of view during long observations or astrophotography sessions. With a well-aligned equatorial mount, only the RA motor needs to run continuously to compensate for Earth’s rotation, while the declination (DEC) motor makes occasional minor corrections. A equatorial mount with GoTo capabilities rely on precise alignment to accurately locate and track objects in the sky. Proper polar alignment improves the accuracy of the mount’s GoTo functionality, making it easier to find and observe specific celestial objects.

Note

•  Polar alignment is specific to equatorial mount mode, which needs to align with the Earth’s rotational axis for accurate tracking. Alt-Azimith mount mode, on the other hand, moves in altitude (up and down) and azimuth (left and right) and does not require alignment with the Earth’s axis.

To perform a Polar Alignment with the Hand-Controller.

1. Start by aligning the mount with three or more stars.
2. Then, go to a bright star near the NCP or SCP with a Declination between 50 and 80 degrees and center it.
3. Select the Polar Align option from the Align Menu. The mount will then shift the star out of the center based on its alignment model.
4. Use the altitude and azimuth knobs of the mount to re-center the star.
5. Optionally, you can repeat this process one more time for greater accuracy.
6. After polar alignment, remember to clear the model and redo the n-star alignment, especially if you’ve adjusted the polaris position using the knobs. This ensures accurate tracking and alignment with celestial objects.
