Hi! This driver provides both telescope and focuser interfaces each of which may be used by separate programs. See my Observatory Control page for more information. That's most of a working telescope mount controller (just need to add the Declination or Alt axis) and can be used with my Android App and/or a PC for control. 1 1. Donation is not required by any means, so please enjoy your stay. Alt-Az Adjustments. but lets the Arduino take control of the mount. It's a nice mount (cheap, portable and very easy to use), but to get To control a computerized telescope mount with your PC requires some additional software and drivers such as ASCOM. Rubber tube to use as hose to connect the handset to the telescope mount. cables USB-Bluetooth switch Simple handbox socket Bluetooth status indicator: flashes if not paired; on if paired. Control Homing. . Do this by tapping the object in the sky chart, or by searching for it by name. I decided to build an Arduino digital setting circle for my mount because it's really hard to buy Tangent Instruments boxes cheaply, and the Argo Navis (the Lexus of telescope digital setting circles) is quite expensive. One is a Home/Reset where you manually move the telescope and the other is a Find/Home where OnStep moves the telescope. The RA fine adjustment knob on the EQ5 mount turns 144 rotations for every full rotation of the telescope's RA axis. The ST4 port is a very basic interface. . Control Your Telescope Using Stellarium & Arduino by NelsonFerraz I am fascinated by astronomy since the first time I looked to the night sky. After completing my homemade telescope mount it was powered by a Meade DS motor kit. . You just need to enter the correct settings for control and USB communication between the computer and the telescope. Today. Remote telescope control via a STELLA Wi-Fi connection. Select that same object in SkySafari to make it the current target object. GEM Telescope Mount Control with an Arduino Mega The goal of this project is to enable conversion of a non-motorised Equatorial Telescope mount to an goto capable mount with tracking.

Everybody it seems has written their own Arduino-based motor focuser controller, of which the most popular is probably the SGL Observatory Automation version. Ok, here's a quick update, firstly I should have said that pin 7 is the shutter, and it has it's own LED (which is also green). The world's first standalone Arduino-based telescope control Goto. Essentially, when changing directions in an axis, there is a short period of time where the drive gears do not mesh teeth. Demonstration of Arduino telescope control on my homemade telescope mount.Astronomy and astrophotography involves a lot of process control, and the Arduino i. EQ Track comes in different "flavors . But using the quad' will require measuring the amount of backlash, and using the mag encoder is much simpler. The control box is attached to the telescope on a 0.5m long length of rubber tubing. Dane Gardner has found a way of incorporating higher-end features into a more affordable scope by making use of the WiFi capabilities of a Raspberry Pi Zero W. This article first appeared in The MagPi 79 and was written by David Crookes. EQMOD is a popular set of software tools used by many astronomers to control the Skywatcher HEQ5, NEQ6 and other mounts directly from a PC.

Physically point the scope at a real star in the sky, using SkySafari's arrow buttons or the scope control panel. (ATM) with electronic board schematics and embedded software to control their telescope mount via stepping motors. Actually, all the stars describes a circumference centered at the pole star. We asked Steve Richards to write an overview of EQMOD with details on some of its many features and how to use them. My design objectives for a telescope joystick motion controller: (1) The scope moves in graceful arcs and accelerates/decelerates smoothly. so here you go. Stellarium 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). rDUINO Scope is based on Arduino Due board and utilizes the code and few sensors in order to collect needed data to control the telescope mount. Recently, I bought a 8" Newtonian telescope that came with a Dobsonian mount. For print use ABS with 100% infill or create from metal (recommended for heavy telescope). The slightest touch can send vibrations rippling, from the scope to the mount, through the tripod to the ground and back up. The Telescope Control plug-in allows Stellarium to control a telescope on a computerized mount (a "Go To" or "Push To" telescope) and offers a graphical user interface for setting up the connection. . This project consists on a first approach to control a telescope mechanism, builded from scratch and based on Arduino microcontroller, from a computer with GNU/Linux and the Stellarium software. Commercially available mount options have a starting price of several hundred pounds and range up to . If you own a telescope capable of high magnification, you know that the stars can jump around quite a bit when you're trying to achieve "perfect" focus. There's one pin per. 3. .
