STOP!!! Read the Instruction BEFORE setting up and using the mount! Worm/gear system damage due to improperly use will not be covered by warranty. Questions? Contact us at [email protected] Instruction for CEM120 Gear Switch and Axle Locking Knob Both RA and DEC have the same Gear Switch and Axle Locking Knob, the operations are the same. Gear Switch Axle Locking Knob As an example, here are the positions for the Gear Switch and Axle Locking Knob for RA axis: Fig.1: When transferring or installing the mount, lock the Axle Locking Knob and disengage the Gear Switch . So the RA won’t swing and there is no force applied onto the worm/ring gear. Fig.2: During mount balancing process, pull and turn the Axle Locking Knob to release it and leave the Gear Switch at disengaged position . Now the mount will swing freely in RA direction.

Observational Astrophysics Lab Manual Lab 1
1 P139 - Observational Astrophysics Lab Manual Lab 1: Deriving the Mass of Jupiter or Saturn Professor T. Smecker-Hane Version 4.0 Sept 25, 2007 1 Introduction The mass of a planet can be determined by measuring the orbital period, τ, the time it takes to complete one orbit, and the orbital radius, A, a constant assuming the orbit is circular, of one of its moons. Doing this independently for a number of moons rather than just one allows you to decrease the error in your derived mass. For Jupiter, there are four easily observable moons. Listed in order from smallest to largest A are: Io, Europa, Ganymede and Callisto. These are commonly referred to as the Galilean moons, because Galileo discovered them in 1610. For Saturn, there are ﬁve easily observable moons. Listed in order from smallest to largest A are: Enceladus, Tethys, Dione, Rhea and Titan. 2 Theoretical Framework for the Experiment Use your knowledge of Newton’s laws and classical mechanics to determine the center of mass of the system composed of a planet of mass M and a moon of mass m. Recall that the two bodies both rotate around the center of mass with the period equal to τ. Assume that the moon’s orbit is circular, and the distance between the two in the orbital plane is r and r = A, where A is a constant for a circular orbit. Now determine τ as a function of A, m and M. Next take the limit of m << M, as is the case for all the moons of Jupiter and Saturn, and determine M as a function of A and τ.

Maurice Rojas Head of Department, Dimitris Lagoudas August 2011 Major Subject: Aerospace Engineering iii ABSTRACT Bouquet: A Satellite Constellation Visualization Program for Walkers and Lattice Flower Constellations. (August 2011) Mandakh Enkh, B.S., Texas A&M University Chair of Advisory Committee: Dr. Daniele Mortari The development of the Flower Constellation theory offers an expanded framework to utilize constellations of satellites for tangible interests. To realize the full potential of this theory, the beta version of Bouquet was developed as a practical computer application that visualizes and edits Flower Constellations in a user-friendly manner. Programmed using C++ and OpenGL within the Qt software development environment for use on Windows systems, this initial version of Bouquet is capable of visualizing numerous user defined satellites in both 3D and 2D, and plot trajectories corresponding to arbitrary coordinate frames. The ultimate goal of Bouquet is to provide a viable open source alternative to commercial satellite orbit analysis programs.
