Observing the moon and planets

Follow

Key Takeaways

  • the eVscope was designed to observe very faint celestial objects that are very large but very far, like nebulae and galaxies, or very small but very close, like asteroids and comets;
    • in contrast, the moon and most of the planets in our solar system are considered very bright;
  • observing the moon and planets is done in “live view” mode (as opposed to "enhanced vision" mode) and will not play on the eVscope strengths. Resulting images will not be significantly better than the ones that can be observed in a regular telescope of a similar size;

The eVscope was designed to provide stunning images of the several thousands of interesting objects like galaxies and nebulae hundreds, thousands, or even millions of light years away. These deep-sky objects are very far and thus very faint and it is often not possible to observe them with such a compact telescope. The eVscope "enhanced vision" mode not only allows for these distant objects to be visible, but they appear in colorful details directly in the eyepiece or on the app.

Being a telescope, it is off-course also possible to observe our moon and planets from our solar system like Mars, Saturn and Jupiter. You can distinguish some of their structures (rings of Saturn, moons of Jupiter, phases of Venus etc.). Using the eVscope you can even see more distant planets like Uranus and Neptune, which can be extremely difficult to pinpoint and observe with a classical telescope.

Observing the moon and planets

Once the eVscope is set up and the sky tracking is on, use the GoTo button to point the eVscope on your desired celestial object. Gain (dB) and exposure time (ms) will have to be manually adjusted in order to view the moon or the planets. We recommend using the values below in your settings, which are found under the eVscope tab of the app:

 

  Planet Moons
Gain (dB) Exposure (ms) Gain (dB) Exposure (ms)
Moon 0 5 - 20    
Venus 0 0.3 - 10    
Mars 5 5 - 30    
Saturn 5 10 - 30 25 100
Jupiter 5 5 - 20 25 100

Note: remember the moon and planets are so bright they cannot be observed using "enhanced vision" mode.

GoTo Moon

Because of its brightness and proximity, a GoTo Moon may not center Earth’s natural satellite, our Moon, exactly in the eVscope's field of view. Follow these simple steps if this occurs:

  • At the end of the GoTo Moon, open the live view settings and make sure Gain (dB) and Exposure Time (ms) are not set to "auto";

    Note: depending on the phase of the moon, the image you see may be very bright

  • Slowly reduce the Gain (dB) by dragging the control to the left and observe in which direction the light disappears;
  • Once your screen is almost dark, press on the settings icon to reveal the joystick and tap on the arrows in the direction of the remaining light source

    Tip: tapping the arrows allows you to control the movement of the eVscope a lot more precisely than the drag and hold motion of the joystick

  • Repeat this operation as necessary (usually once or twice should be enough) until the moon comes into full view of the eVscope.

Here is a short video showing you what this procedure should look like, with a beautiful waxing moon crescent when completed.
