How to use Unistellar eVscope?

To utilize the Unistellar eVscope effectively, you’ll need to follow several essential steps. Begin with the following guidelines:

  1. Setting up the tripod: It’s essential to set up and test the tripod thoroughly before mounting the eVscope. Extend the tripod legs to the desired length, ensure it’s on firm ground, and use the bubble level to adjust the legs for leveling. Once the tripod is stable, mount the eVscope and secure it with the mounting screws​​.
  2. Thermalization: Allow the telescope to acclimate to the outdoor temperature before observing, which typically takes 15-30 minutes. This step ensures that the primary mirror maintains its shape and focus, providing sharp images​​.
  3. Powering on and connecting: Long press the eVscope’s power button to turn it on, and connect your device to the eVscope’s WiFi. Open the Unistellar app, which will provide status information and access to the telescope’s features​​.
  4. Orientation process: Once the eVscope is mounted and stars are visible, initiate the orientation process. This procedure allows the telescope to determine its pointing direction​​.
  5. Focusing: Use the telescope’s Bahtinov mask for focusing. Place it on the front end of the telescope and center a moderately bright star in the field of view. Adjust the focus wheel at the back of the telescope until the bright lines created by the mask symmetrically cross the central bright spot of the star​​.

Who is Unistellar eVscope 2 intended for?

The Unistellar eVscope is intended for people who are interested in astronomy but don’t have the technical knowledge about telescopes and astrophotography. It is a user-friendly telescope without the need to know the night sky or star alignment, polar alignment, and such things.

Affordable alternative to Unistellar eVscope

For those seeking a similar experience to the Unistellar eVscope without the high cost, a custom setup can be an effective alternative. This approach requires some technical know-how.

  1. Telescope: The Celestron NexStar 130SLT is recommended. It’s a computerized telescope with an alt-azimuth mount and a slightly larger aperture than the eVscope.
  2. Camera: Opt for the ZWO ASI 224MC, which shares the same camera sensor (IMX224) as the eVscope.
  3. Software: Use a laptop (with USB 3.0 or 2.0) and the free software SharpCap for astronomy. The Live Stack feature in SharpCap can produce images similar to those from the eVscope.

This DIY alternative offers more versatility than the eVscope, though it comes with a learning curve and requires more setup and operation effort.

Price comparison:

  • Unistellar eVscope: $2,999
  • DIY Setup: Approximately $750 (excluding laptop), plus the need for technical skills.
