With the kit eyepieces you can't get overly high magnification (But still better than some other telescope's kit eyepieces).

• Telescope:

  • Aperture: 100mm
  • Focal-length: 400mm

• 10mm eyepiece:

  • 40x magnification (400/10). Simulation! https://imgur.com/maPuiPQ (you could tell it's not a star)

• A barlow (cheap ones reduce the contrast) or a HR Planetary clone eyepiece would allow for a bit more magnification.

  • 3x barlow + 10mm eyepiece: 120x. Simulation! https://imgur.com/KmjibBo - Probably more realistic https://imgur.com/3JahkVv especially when using cheap eyepieces/barlows
  • 5x barlow + 20mm eyepiece: 100x. (5x barlow and 10mm eyepiece are too much! The image will get too dim. But as the kit eyepieces are short and the cheap barlows not accurate, you might get something in-between.)

Videos are difficult as they don't represent the visual view. But that's close; https://www.youtube.com/watch?v=uaxxsIqC9vA with another eyepiece or barlow that's not cheap.
