Water Proof

The actual portion of the sky you see through the telescope.

How wide the view looks when looking through the eyepiece — a larger angle gives a more immersive experience.

It’s how far back you can hold your eye from the eyepiece and still see the whole image — important for comfort, especially if you wear glasses.

Diopter adjustment allows you to fine-tune focus for differences between your left and right eyes, ensuring a sharp image without glasses.
