Can you see the Cartwheel Galaxy through the telescope?
The Cartwheel Galaxy is not visible through most telescopes. Its location 500 million light-years away puts it beyond the reach of typical amateur equipment. The galaxy’s distance results in a faint appearance, requiring powerful professional telescopes for detailed observation. Space-based observatories like the James Webb Space Telescope are necessary to capture clear images of the Cartwheel Galaxy. The galaxy’s brightness of around 15th magnitude makes it invisible to the eye and challenging for telescopes.
Telescopes with a diameter of at least 8-10 inches are needed to glimpse the Cartwheel Galaxy. With large amateur telescopes, the galaxy appears as a patch without discernible structure. The Cartwheel Galaxy’s ring shape, spanning about 150,000 light-years across, remains unresolvable for ground-based observers. Astronomers rely on imaging techniques and exposure times to study the galaxy’s features. The Cartwheel Galaxy’s views through amateur equipment are limited to smudges of light.
