How to Collimate Your Newtonian Reflector by Vincent S. Foster
Before you can observe with a Newtonian reflector telescope, you need to align or collimate its optical parts. The goal of collimation is to insure that both the primary and secondary mirrors as well as the eyepiece are correctly lined up to give clear, sharp views.
You might think that collimation begins with the primary mirror because it is the most important part of the optical system. Curiously enough, it does not. Collimation is done backwards, starting at the focuser and working back to the primary. The reason is simple. Before you can adjust the most important optic, all of the less important optical parts must be doing their jobs properly. Think of it that way and it makes perfect sense.
For fast and efficient collimation, you need a laser collimator. Laser collimators are very accurate and easy to use. In general you adjust the mirrors until the beam hits the center dots on both mirrors and returns right back into the output hole of the laser.
To achieve the best collimation it is imperative that you "center do...
Mirrors are first introduced in part one of the novel where Clarisse is describes as a mirror by Montag. Also presented by Granger towards the end of the novel, the mirror is a symbol of the lacking self-reflection but also it cure. Mirrors reflect a perfect image of a person back at them – an image that is neither tarnished nor beautified. Mirror here are a symbol of seeing within one’s soul in pursuit of rebirth, and are a tool to be used in the search what has gone terribly wrong in such an empty society. In a society that lives without living, thinking or feeling like Montag’s looking into a mirror ma spark a thought, and a thought may spark that internal rebellion. Furthermore, metaphorical mirrors are of equal significance when understanding this symbol. Clarisse is Montag’s inner mirror; she reflects the personality and life of Montag back at him, allowing him to learn and question what he sees. Montag is also Faber’s mirror – he reflects Faber’s recent emptiness and his cowardice at not attempting release society from its suffering. Mirrors are a great symbol of self-actualization that leads to rebirth in the novel Fahrenheit
Erik Erikson was heavily influenced by Freud but while Freud was an ID psychologist, Erikson was an ego psychologist. Erikson stressed that the development of the ego depended heavily on personal and social aspects. “According to Erikson, the ego develops as it successfully resolves crises that are distinctly social in nature. These involve establishing a sense of trust in others, developing a sense of identity in society, and helping the next generation prepare for the future” (McLeod, S. 1970). His theory focused on personality development through eight distinct stages. He believed that personality progressed in a stacking or pre-determined manner, this is referred to as the epigenetic principle. One must
The mirror symbolizes Montag’s self-reflection. Mirror was mentioned in a lot of places in the book. There was a time when Montag did not know himself and Clarisse helped him to find those. She reflected the odds of society and helped Montag see things clearly. At the end of the story Granger suggested that they build a mirror factory and look in them. He suggested this because he recognized the importance
This reflective essay will demonstrate the concept of reflection. The model of reflection by Driscoll, 2007 has been followed in this essay to reflect the clinical skills that I have studied and practiced in week 7to week 9 of this unit which assisted me to get prepared for the practical experience which I will commence at the end of this semester. I have practiced numerous skills during the practicals class, but this essay will be a focus on taking care of bedsore and wound management.
My sixteen week class in English 111. I was really nervous about this class. Because English has never been my strong point. This class has hard, but fun all at the same time. I learn a lot from this class. Meanwhile,the first day of class you handed a paper with a question on it. “The first thing I want to say to you who are students is that you must not think of being here to receive an education; instead, you will do much better to think of being here to claim one.” Even though putting my all in what I have learned, claiming my education with hard work because using the skills of the meal plan, as we write to different audiences and learning to be a Critically thinker as I start becoming a critically-Literate Citizenship.
“A young girls introduction to womanhood is reflected in the rites and traditions of a culture.” (Samarisa, Arts). Like most women, becoming a woman means learning how to take care of their selves on their own, defining who you are for yourself, who you want to be, having future goals set, and developing tools to face the world. Fortunately, I have learned how to apply these skills during my wonderful experience in the 2014 Delta Cotillion. This event has made a remarkable turning point in my life because it was the biggest and most affectionate assembly any girl could ever be in and it was also teaching me to know where and how I wanted to pursue my dreams. Taken forward into life as a woman, these virtues encouraged a sense of responsibility
...ossessed with three dimensional attributes. The optical effect may be explained by the fact that the human eyes see an object from two viewpoints separated laterally by about six centimeters. The two views show slightly different spatial relationships between near and near distant objects and the visual process fuses these stereoscopic views to a single three dimensional impression. The same parallax view of an object may be experienced upon reflection of an object seen from a concave mirror." (http://www.freepatentsonline.com/4229761.html).
Introduction A service learning experience is designed to enhance a student 's growth in personal and social development and to obtain an understanding of community involvement. For my service learning experience, I volunteered at Change Point Center. In this reflection paper, I will discuss in depth information about the services that Change Point provides, my goals while I was there,and what I ultimately learned from this experience. Information about this experience Change Point center is located in Hot Springs, Arkansas and is a non-profit organization. The role of the agency is to help women in crisis pregnancies as well as families that face crisis situations.
Throughout this class, there were many social issues and whom they affect discussed. I loved this class for the reason of getting myself more familiar with what is happening around me and around everyone else in the world. This class was an eye opener to major social issues that people are faced with so in this paper, I am going to talk about the seven objectives we were supposed to obtain from this class.
The principle behind the refractive telescopes is the use of two glass lenses (objective lens and eyepiece lens) to gather and bend parallel light rays in a certain way so that the image fits the size of the eye's pupil. Light rays is gather through the opening of the telescope called the aperture and passes through the objective lens and refracts onto a single point called the focal point. From there the light rays continue the same direction until it hits the eyepiece lens which also refract the light back into parallel rays. During the process, the image that enters our eyes is actually reverse of the original image and magnified because the size in which we preceive the image.
The Hubble Telescope is the world’s first space-based optical telescope. The Hubble telescope received its name from American astronomer Dr. Edwin P. Hubble. Dr. Hubble confirmed an ever expanding universe which provided the basic foundation of the Big Bang theory. The first concept of the Hubble telescope came from Lyman Spitzer in 1946, who at that time was a professor and researcher at Yale University. In 1946, Professor Spitzer believed that Earth’s atmosphere blurs and distorts light, and a space orbited telescope would be able to overcome this problem.
In this “Digital Age” that we currently live in, it becomes very easy for an individual to become infatuated with the amount of social media outlets available on the internet. Platforms like Facebook, Twitter, Instagram, and Snapchat all revolve around the idea of showcasing one’s personal life for the sake of receiving positive feedback or attention by peers and strangers from the outside world. An episode of the Netflix sci-fi anthology series, “Black Mirror,” decides to tackle this topic in a surreal yet imaginative way. The episode in particular, “Nosedive,” investigates a hypothetical future or alternate universe where social media profiles and star ratings have become the norm. The plot revolves around a young lady named Lacie, who
The refracting telescope is one of many different types of telescope. Refracting telescopes work by refracting the light through an initial convex lens, (known as the objective lens), then through another convex lens (known as the eyepiece lens). These two lenses focus the light into the eyepiece so we can see the image clearly.
I will fund my exhibit through donations and sales. I would reach out to the community, explain my exhibit and ask for donations, but I would primarily generate revenue through selling items related to the exhibit like prints of the works being shown, creative posters, key chains, t-shirts and other mementos. Additionally, I would have bake sales and fairs and other activities of a similar nature.
Isaac Newton created the first 'practical' reflector in 1668, which included a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope. With time, telescopes became bigger and more sophisticated, and astronomers discovered more stars and galaxies. They were also able to calculate the distance between stars. Most of the large optical telescopes used for research today are reflectors.
