For anyone who has ever dreamed of exploring the heavens with a telescope. The location of trig points, or triangulation stations, are precisely listed by the Ordnance Survey, the UK’s mapping agency. You will see these formulae being used in the Arduino program shown in a later step. ASCOM telescope focuser with Arduino. So to make sure that the device would work, I tried to quantify each source of error, and do some statistics to predict the performance of the system. The code is compiled right along with your sketch. Close-up of the main circuit. I'm putting it online so you can access it there, and watch my slow progress. you have the thing! $17. Results within that black circle would be visible to the observer. LM35 is a precision integrated circuit whose output voltage is . Telescope automation. This book presents practical knowledge the author acquired rather painfully, while working "in the trenches" for several years in major engineering companies scattered across several continents. is an open source project with a lot of helpful astronomy features, including a plugin that allow a connection between a computer and a telescope controller (like celestron, meade or sky-watcher). Repeating this test a few times gave me enough results to provide a mean figure of GPS accuracy, which was 11.6m. The program constantly updates the position information, to assist the observer in tracking the target object as it moves across the night sky. (altpot == altpotgood) { //This section controls which of the four LEDs are lit, to indicate which direction the telescope needs to be moved in. This project aims to make a system that can effectively track celestial bodies (such as planets ) with a fair amount of accuracy. The complexities arise with GOTO. Other comments I have received say that this file has to be in the IDE library. Where a = altitude, ϕ = observer’s latitude, δ = declination and H = hour-angle.

Usually you can expect to find a link that will download a zip file with all the files included and laid out in a directory structure already. An affordable magnetometer and gyroscope unit (the 1120 3-Axis Accelerometer and Magnetometer from Adafruit) was tested, but was found to have an accuracy of greater than 1°, insufficient for this purpose. All relative positions of all astronomical objects are located according to the angles of right ascension and declination (Ra/Dec). And finally, I added the logic to manage the RS232 traffic between all four entities - scope, Arduino, sky-map app, and the Arduino IDE (integrated development environment on your PC). Here’s the list of components I used for this project (note that the above image only pictures a few of them, that’s just a shot of my GPS test setup). You don’t need to do this step unless you’re also interested. This project uses the Arduino shields set of boards. Picture is the . Where H = hour-angle, LST = local sidereal time and α = right ascension. The ATmega2560chip of the Arduino has a 10-bit analogue to digital converter (ADC), which means that the voltage reading from the potentiometer is mapped onto a set of discrete values from 0 to 1023. Found inside – Page viiiChapter 15 aimed to find the interdependency between cost and time problems in construction projects and determine which ... doctors to use telescope tracking, long-range assistance and telecommunication from mobile health providers. I guess you are using code from one of the sub-directories under the “CODE ARDUINO” folder. The pieces above mate the shaft of the potentiometer to that bolt, and the body of the potentiometer to the upper surface of the telescope lower plate, thus meaning that when the mount is rotated, the shaft of the potentiometer will be rotated relative to it’s body (allowing us to measure the heading of the telescope). As it has an irregular shape, it is not possible to accurately determine the true centre of the object, hence a partial explanation for the inaccuracy in the Ra/Dec data. Clearly this was not going to be the issue! I'm putting it online so you can access it there, and watch my slow progress. Open project code - Circuit_07_BarGraph; Select the board and serial port as outlined in earlier section. Project Code. Appreciate any help with this. Optical encoders do not have a sufficiently high resolution if used in a 1:1 ratio with the movement of the telescope, and would therefore require a gear system to raise the number of counts per degree of movement, hence why potentiometers with a linear resistance output were chosen. I took the GPS unit to six of these locations, and test results were taken, so that the device’s figures could be compared to the known OS coordinates. Post the program you are trying to use. I have lots of experience with computers, some electronics, and no coding. This is a twisty mess.
