Making a Homemade Telescope

People of all sorts of ages enjoy homemade telescopes. And being able to make your own just heightens the pleasure. There are several different methods for making a homemade telescope, but the basics are usually about the same. Below is a quick overview of the information and supplies you will have to have to begin.

Supplies Needed

You need a small amount of things to begin. Below is a supply list of the thing you can use to make your telescope at home:

Two Lenses: One needs to be a small concave, and then a larger one that is convex (the concave lens is thinner in the middle than on the edges, and a convex one is the opposite).

Two Tubes of Cardboard: The kind of tubes that come with the wrapping paper on them work great, or anything like them.

Building a Homemade Telescope You have your supplies now, this is the stage where you assemble your telescope. You begin by putting one of the tubes inside the other tube. You will have to figure out what distance apart the lenses should be. You figure this by looking through the small lens while having the larger lens in the front. When you get the right distance the object will be in focus, then measure the distance between the lenses to use as a reference for your new homemade telescope.
 
When the tubes are together they need to be double in length of your distance you figured. The convex or larger lens should be applied at the front end of the tubes, glue it on the tube. Be cautious not to let any glue fall on the lens, this would ruin the view of your homemade telescope.
 
Now you glue the concave lens onto the opposite end and this makes and eyepiece for you. Be sure you have these lenses lined up properly for you to be able to view what objects you desire through them correctly. The tubes should be in great condition without being broken or bent, they need to be sturdy enough to hold the lenses too and keep them parallel. If they don't you will just be wasting your time.

If you manage to align the two lenses and keep them that way at the correct distance, creates a good sight line, and also keeping them parallel, your new telescope that is homemade will suit you and your family just fine. This is also a good project for a school class.

SOLAR KUSH LOAD - BEST WAY TO SMOKE TASTY BUDS - Watch In HIGH QUALITY

Saturday morning tasty kush solar rip with my friend's gigantic magnifying glass. Smoking with the sun is sick because first it heats the bud before combusting so you get much more taste than if you toked it with a lighter. LOGIC: The sun emits a particle known as a photon, which carries visible light to earth. These photons contain energy, which they radiate in the form of heat. When you put a magnifying glass in the paths of these photons, the convex lense of the glass narrows and focuses the photons, making them converge on a narrower point then if the lense wasn't there. This concentration of photons concentrates the heat that they emit, heating and eventually igniting the super bomb, tasty nugs of kush I got. Word. WATCH IN HIGH QUALITY

Concave mirror formula (By - al tahir public high school khushab) part 3

This video tutorial is about how an image of an object placed in front of a concave mirror is formed? The ray from the object fall on the mirror after the reflection the ray passes from the focus and image is formed at 2F. The image is inverted. For the derivation of the equation watch the tutorial video of Algebra.

Mode image from AlGaAs waveguide (vertical + lateral tuning)

CW wavelength = 1594nm CW input power = 10mW Waveguide length =~1cm Waveguide width = 4um Material = AlGaAs (Aluminum Galium Arsenide) Other dimension: unknown. Coupling: fiber - waveguide - fiber Venue: SF-4107 Fiber optics communcation laboratory, University of Toronto The mode image is magnified because the objective is placed in such a position that fringes can be observed. Note that the fringes from the input lensed fiber are passed through the waveguide because the waveguide is to transmitting lights. There is no linear lens effect in the waveguide. The vertical position of the middle stage of Newport Ultralign 561 middle stage is being tuned: 1. The taper tip of the lensed fiber is above the waveguide. The light is reflected from the surface of the waveguide. The bottom screen is bright because the image is inverted by the convex lens. 2. The waveguide is raised such that the taper tip of the lensed fiber is on the same level of the guiding layer. The light from the lensed fiber is guided by the waveguide, and a bright circular (with fringes) appears at the output. 3. The waveguide is still raised such that the taper tip is pointing the substrate. Larger circular fringes can be observed, which is due to the input light from the lensed fiber. 4. The waveguide is being raised. Horizontal fringes appear due to the reflection of light inside the substrate, leading the interference pattern. The above steps are being reversed in the video, and the mode image is formed at ...

Victoria School LSS TFU: Focus Point..

A little video we made for our Physics TFU Project. It's all about trying to burn an object using Reflection and Refraction. Group Members: Isaac Tay, Low Qi Xun, Abdul Aziz, Li Ming Ren. Script: How to burn an object using the concept of refraction or by reflection light rays from the sun. Based on the myth of the Archimedes death ray. These are the apparatus we are using. An empty can of soda. Metal polish Now Start polishing the bottom of the can to make it mirror-like. Now we head outdoors at midday, around 12noon to 2 pm, when the sun is bright and strong. Find the focal point by moving the leaf up and down slowly. Smoke Watch caaaarefully. How does it work? The bottom of the can serves as a parabolic concave mirror which reflects and converges the suns rays onto the focal point. This concentrates the heat of the sun. This can be seen in the diagram, where we have traced the suns rays as they travel and are reflected by the concave mirror which is the soda can, to converge onto a point. Refraction These are the apparatus we are using. Find the focal point. Now, wait as the point of concentrated suns rays burn the leaf. Check it out in Fast forward. How it works. The convex lens of the magnifying glass will focus the suns rays on to a point. This concentration produces a point source of heat, similar to the experiment using the soda can. This heat can burn a hole in the leaf. The magnifying glass can converge the suns rays because of the convex lens and the refraction ...
