WebMar 30, 2024 · For beginner’s telescopes look for a focal length of at least 600mm. Anything less than that will limit your viewing experience too much and would only be recommended for kids’ telescopes. Beyond that, the answer is going to depend on what type of celestial objects will be your main objective. WebThat's why it gave you this distance between lenses. The distance between lenses is 33 centimeters. So if the distance from this 1st lens is 18 well the difference has to be equal to this length. So 33 minus 18 is going to be 15, whoops. 15 centimeters will be where the "object" for this 2nd lens is going to be.
