π The Perseids, the stars of the summer
The most anticipated spectacle of the month is undoubtedly the Perseid meteor shower , which will peak on August 12th around 10:00 p.m. (Spanish time) . However, in 2025, observations will be partially affected by the bright Moon , which will have reached its full moon just three days earlier. Even so, it's worth attempting to witness this phenomenon, considered one of the most beautiful in the astronomical calendar.
πͺ Planets visible in August

π Astro Telescope Observation Tips
At Astro Telescopes, we want you to enjoy this astronomical calendar to the fullest. For these dates, we recommend:
- Medium-aperture reflecting telescopes , ideal for observing the lunar surface in its various phases.
- Wide-field astronomical binoculars , perfect for following the Perseids and enjoying the summer constellations.
- Lunar filters , very useful for reducing the brightness of our satellite and better appreciating the details on nights close to the full Moon.
- Portable and easy-to-assemble telescopes , an excellent option for nighttime getaways outside the city.
This August 2025, the sky invites us to look up and let ourselves be carried away by the magic of the Universe. π
