The eyepiece
What is the eVscope 2 eyepiece ?
The technology OLED display has extremely high-contrast with True black, with an
optical setup designed to stream the sensor's view. The result: mind-blowing visual
quality for your observations of the dark sky.
How to use it?
You can adjust the dioptry and sharpen the image based on your eyesight, especially
if you wear glasses or contact lenses by rotating the side knob counterclockwise
fully, followed by 3 to 4 clockwise turns until perfectly adjusted to your sight.
The fi eld of view cannot be changed, even with a Barlow lens.
The battery
The eVscope 2 comes fully charged and ready to use.
What is the eVscope 2 battery ?
Battery’s characteristics: Lithium-ion (6 x 18650, 15 Ah) - lasts up to 9 hours.
A rechargeable Lithium-ion internal battery is built into your eVscope 2. The battery can be
replaced in the event of malfunction or permanent damage.
How to charge the battery ?
Use the enclosed USB-C charging cable and power plug adapters to plug your eVscope
2 into a power outlet. A power bank can be used to charge your eVscope 2 as well (we
recommend a USB 5V).
For the most effi cient charge of the battery, the maximum current used by the eVscope 2 is
2.4 Amps. For the charge range we recommend >2A. 1A will also work but the charging time
will take longer.
What does the blue flashing light indicate ?
While charging, the LED located on the power button fl ashes blue. As the battery is charging,
the number of fl ashes will decrease. When the battery is fully charged, the LED is steady
blue. Your Unistellar App also indicates battery levels.
Avoid “fast charging” technology (9V, 12V); it may not charge the battery (and charger may
not be detected).
Partial battery discharges are healthier for your device than long discharges: high
discharge rates contribute to damage and strain on Lithium-ion batteries.
What if my power supply is damaged ?
If damaged, the charger is a standard one, you can use a USB-C USB cable. Use a good
quality power supply.
For long term storage, we recommend charging your battery to 70% and
charging it at least every six months. Keep your telescope disconnected, and
away from heat and moisture. Recharge your eVscope 2 fully before your next
observation.
