Edu Science Telescope How To Use I Have A Edu Sciences Telescope From Christmas From Last Year But I Was Wandering This?

I have a Edu Sciences Telescope from Christmas from last year but i was wandering this? - edu science telescope how to use

somehow my damn telescope has only a few millimeters, eg 20 mm and 15.10 mm to 2.5 mm, I think, but not quite sure, but I try to find some eye thats over 20 mm, but everyone in my telescope can fit us a good place to get parts of the eye that can help us find the right parts of the eyes, as 20 mm can see is also minimized for us, but we always have greater price

Thanks
