Celestron Dobson telescope N 305/1500 StarSense Explorer DOB (79899)

The StarSense Explorer telescope revolutionizes stargazing by using your smartphone to analyze the night sky and calculate its position in real time. Designed with beginners in mind, the StarSense Explorer app features a user-friendly interface and detailed tutorials, making it feel like you have a personal guide to the cosmos.

Effortless Navigation:
Say goodbye to complicated star charts, inaccurate planetarium apps, and bulky computerized mounts. With StarSense Explorer, locating celestial objects is faster, easier, and more accurate. Within minutes of setup, you’ll confidently navigate the night sky. Simply place your smartphone in the unique StarSense dock and launch the app. After a quick 2-minute alignment with the telescope’s optics, the app generates a list of visible celestial objects. Select an object, follow the onscreen arrows to move the telescope, and when aligned, the bullseye turns green—indicating it’s ready for viewing.

Advanced Technology:
StarSense Explorer uses patent-pending technology combined with your smartphone to determine exactly where the telescope is pointed. Its Lost in Space Algorithm (LISA), similar to those used by satellites for orientation, matches star patterns detected overhead with its internal database for precise positioning.

Light Pollution Friendly:
Even in light-polluted areas, StarSense Explorer can identify major celestial objects such as Jupiter, Saturn, Venus, the Orion Nebula, double stars, and more.

Dobsonian Advantage: Simple and Rapid Assembly
Dobsonian telescopes are known for their simplicity and affordability. They consist of only two main parts that can be assembled quickly. Compared to equatorial mounts of similar size, Dobsonian mounts are much less expensive. These telescopes are primarily designed for visual observation, allowing you to discover the wonders of the night sky with ease.

N 305/1500 to 1525 Telescope: Large Aperture for Advanced Observing

This Newtonian reflector telescope features a large 305mm aperture that ensures years of astronomical exploration without reaching its limits. Experienced observers will appreciate its ease of use and breathtaking views. Compared to a 10-inch Newtonian telescope, this 12-inch model offers 1.4 times more light-gathering power and a 0.1 arcsecond improvement in resolution. The fast focal ratio ensures bright images suitable for deep-sky observation.
