[Dessislav Gouzgounov] wanted to build a small piece of hardware — a GoTo for his telescope. This handheld controller would allow him to use software to align the telescope with whatever celestial body he’s checking out.
Many GoTos simply interface with a laptop, but [Dessislav] built a standalone system centered around an Arduino Due and 240×400 touch screen, with GPS, RTC, and Bluetooth under the hood. It works on both hemispheres and contains a database of 250 celestial objects, features different speeds for time-delayed tracking of celestial, lunar, and solar phenomena, and it can work with any stepper-equipped telescope.
We covered [Dessislav]’s previous version of the RDuinoScope, but he’s improved the project considerably with over 2,400 lines of code including a new menu system and added a star atlas showing the location of the sky at which the telescope is currently pointed, among other improvements. The project is open source and you can learn more about it on [Dessislav]’s project page or check out his code on GitHub.
