What ordered and was shown in the image was a 100X telescope kit. if my eyepiece focal length is 50mm, then the magnification will be: 1000/50 = 20x. Measure the diameter, if necessary, and mark it with a pencil. The flat side of the lens needs to be against the cap. There is also a second eyepiece which magnifies 50x. The phase telescope, also commonly referred to as an auxiliary telescope or auxiliary microscope, consists of a simple two or three lens telescope (illustrated in Figure 7) arranged to function as the objective and eyepiece combination of a miniature optical system that is intermediate between a telescope and microscope. To make a simple telescope at home, you will need the following: two magnifying glasses - perhaps 1 - 1.5 inches (2.5-3 cm) diameter (it works best if one is larger than the other) a cardboard tube - paper towel roll or gift-wrapping paper roll (it helps if it is long) duct tape; Eyepeice lens : Double convex lens of Diameter= 25 mm and focal length=4cm. This will make the process flow smoothly. A 20 mm eyepiece on a 2000 mm telescope (2000/20) gives you 100 power (100x), this makes objects appear 100 times closer to you through the telescope than they appear to your unaided eye.

In general, when the magnification of scope increases, the image brightness, and field of view (FOV) decreases. For example, a 100mm clear aperture is approximately 4", so such a telescope operating at 100x magnification is at 25 PPI (100/4=25). On these telescope types, you’ll find three screws for adjustments on the outside of the secondary mirror. The slot should be able to hold the large magnifying glass so don’t cut the slot of the tube all the way.

This feature can be manipulated using different combinations of objective and eyepiece lens. The First Time Telescope User's Guide will teach you how to use your new telescope correctly. Eyepieces have their own focal length as well, which, when divided by the focal length of a telescope, determines the magnification capabilities. Magnification=focal length of objective / focal length of eyepiece= 50cm/4cm = 12.5x, resolving power = 120 / Do(diameter of objective in mm) = 120 / 50mm = 2.4, diameter of exit pupil = Do / M = 50mm / 12.5 = 4mm, focal ratio fr = fe / Dep = focallength of eyepiece/dia of exit pupil = 40mm/4mm = f/10, also focal ratio = fo/Do = 500mm/50mm = f/10. (the toilet paper roll is about 40 mm in diameter). Cut down the second slot in the tube for the second magnifying glass. Upon seeing the Moon, I could just see it a little bigger than what would be seen with the naked eye.
