eVscope Data Storage & Memory: Downloading and Uploading Data


Key Takeaways

  • The eVscope storage (also referred to as “eVscope memory”) only fills up when you use Enhanced Vision or Science Observation modes;
    • saving pictures of your observations does not fill up the eVscope memory;
    • the storage capacity of the eVscope allows for up to 7 hours of Enhanced Vision mode. In Science Observation mode, the shorter the exposure time, the more frames it takes, the faster the memory will fill-up;
    • even with full memory (100% data storage used), the eVcope will continue operating normally, and you will still be able to save your pictures. However, you will not be able to take part in community events or citizen science campaigns;
  • Storage information can be found under the “User” tab of the app;
    • “DOWNLOAD DATA” is a transfer of data between your eVscope and your smartphone;
    • “UPLOAD DATA” is a transfer of data between your smartphone and Unistellar’s server;
  • Uploaded data help us create a better user experience and allow you to take part in scientific discoveries or community events.

While using the Enhanced Vision mode or the Science Observation modes, raw data (frames) of the objects you are observing are automatically saved in your eVscope memory. The eVscope storage information is found under the “User” tab.

Note: under the “User” tab you will also find the battery charge gauge, the eyepiece focus helper button, and the button to take a dark frame.

The beautiful pictures that you save during all your observations are not saved on the eVscope but rather on your smartphone, so uses your smartphone storage space instead.

In order to free up (reset) the eVscope storage, it is recommended to regularly download the data from your eVscope to your smartphone and then upload it to our servers. To do so, follow these simple steps:

Data download and upload process

  1. While your smartphone is connected to your eVscope, simply go to the user tab on the app (this can be done once you have returned to the comfort of your home);

  2. If there is data stored in your eVscope, tap on the “DOWNLOAD DATA”, otherwise the button will be grayed out, which means it is disabled;

  3. Downloading the data can take anywhere between a few seconds to several tens of minutes depending on the amount of data stored.

    Note: After having downloaded all the data, the button “DOWNLOAD DATA” may still appear active. By clicking on it or, navigating to another tab and back to the “User” tab, the button should appear grayed out.

  4. Once the download is complete, turn off your eVscope, connect your smartphone to your home internet network, and simply tap on the “UPLOAD DATA” button. Uploading the data can take anywhere between a few minutes to several hours depending on the amount of data and your home internet connection speed for upload.

    Note: If you have a mobile phone contract with unlimited data, we would recommend using this instead of the wifi to upload the data. It is usually a lot faster than home wifi networks for uploads. Please make sure that you are not billed for data usage by your mobile phone company before doing so.

  5. Optional step: to check if everything went smoothly, reconnect your phone to the eVscope. Go back to the User tab of the App. After a few minutes, the amount of data in the storage section should indicate “Storage: 0% used”. The transfer was a success.

Tip: regular users usually go through this process at the end of each night of observation or, at the very least, every time their eVscope data storage approaches 20%. This guarantees they are ready whenever they want to participate in citizen science campaigns or community-based observation events.

Tip: starting the upload process just before going to bed and leaving your smartphone on during the night should allow the data transfer to complete overnight.
