You can easily add a lot of shields and sensors specially designed for Arduino, or you can adapt others.It's easy to find libraries that can help you using a lot of different things.Have a huge community and tons of information online.I personally prefer Arduino for several reasons, including: This instructable will guide you, step by step, how to complete your own controller using Stellarium (astronomy software) and Arduino (open-source prototyping platform based on easy-to-use hardware and software).Īnd, why Arduino ? Well, there is not a simple answer for that. If you are not interested to spend thousands in a go-to mount, this will give you a really good help when you start to point your telescope to the sky.Your telescope will become "famous" among your friends.Your telescope will be customized to fit your needs.You can control your own budget and keep it below 50USD.It's a good contribution to learn a lot of new things (otherwise skipped by using a ready to use solution) like: alt-azimuth and celestial coordinates, local sideral time, earth movement, spherical trigonometry.It will be a lot of fun trying to do something new.Why build a controller instead buying a ready to use one? However, because of my electrical background and because I like to consider myself hobbyist, my first thought was: - I can (and I will) build a DIY controller for my telescope. You can say: Yeah! Buy a goto telescope and you will see your problem solved! Well, you are absolutely right! 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).Īfter a couple of nights using my telescope, I realized that it should be helpful if, at any moment, I can compare my telescope position with the position of the target that I am looking for. To help you to know the sky, there are several software's you can use and stellarium is my favorite one.
It's a nice mount (cheap, portable and very easy to use), but to get what you want to see, you need to know the sky like the palm of your hands (which can be a problem to a beginner like me.!). Recently, I bought a 8" Newtonian telescope that came with a Dobsonian mount. I am fascinated by astronomy since the first time I looked to the night sky.
