Questions & Answers

Q: What beginner telescope do you recommend for someone interested in visual astronomy?

I recommend the Orion xt8 Dobsonian telescope, as it offers a good balance between portability and a great view of the night sky.

Q: Can you suggest some objects to observe in the night sky right now?

The Orion Nebula is a great object to observe, as well as the stars in the constellation Orion's belt. Additionally, the Beehive Cluster and M15 in Hercules are worth checking out.

Q: Is there a telescope or lens with an 800mm focal length that is affordable?

Celestron refractors, such as the 80mm or larger models, are a good option. They provide a wider field of view and are suitable for observing star clusters and other objects.

Q: What happens if you fire a projectile into space at high speed? Will it eventually hit something?

The probability of a projectile hitting something in space is close to zero. The vastness of space, combined with the expansion of the universe, makes it highly unlikely for any object to collide with another.
