See I have made a small one 

Ohh do you use whatsapp or Instagram 

India.

What do you do are you a scientist or what

So @Mandy D where are you from 

What is the aperture of eyepiece lens 

Okay 😄

Yes mm

Around 500mm

As @Cosmic Geoff said 70mm aperture will be sufficient 

And I have the lens of 70mm aperture

Ok cosmic Geoff .

And Mandy D I think Newtonian reflector is too much complicated to make at home

Can you please explain me what is Newtonian reflector??

With magnification of 300x can I see Saturn 🪐 clear

Okay 👍

I am not expert that's why I am asking you all 

That means I should buy the objective lens of 6inch (15cm )aperture for 300x zoom and it's focal length will be?

and eyepiece of 3.3mm FL

Please help me with your experience 

Sorry for some calculation mistake it's 500mm

And 5m means 5 meters?? Please let me know

Hi,

Welcome to SGL. We will need more info on what you are trying to build this for etc. Do you have the lenses already? Or are you still at design stage.

Just a quick observation - 500cm FL is quite long (5m) ! Is this correct?

I want to see Saturn clearly that's why I am making this telescope.Write now I don't have any lenses I am still at design stage and from this formula 

Magnification = Focal Length of Objective Lens / Focal Length of Eyepiece Lens

I have choose the FL 500mm  for 500x zoom 

I am not a expert that's why I have come here for.

500mm/1mm
Magnification≈500x
