Since I aquired an Losmandy G11 mount without any goto provision I decided to create my own solution. I was a bit reluctant to use a Gemini, mainly because of the cost, but also due to the reliability since the servo motors are somewhat prone to failure. I also like to have complete control over the software/firmware so that no "show stopper" issues will ever be a problem for me. Looking around the 'net I saw other goto systems that seemed capable, but either they had needlessly complex hardware or were commercial systems that cost about twice what they should.
OnStep is a computerized goto system, usually for stepper motor equipped mounts though any step/dir interface motor driver (including servo) should work. It was designed, from the beginning, as a more or less general purpose system and provisions were made in the firmware to allow for use on a variety of mounts including Equatorial and Alt/Az (GEM, Fork, Dobsonian, etc.) It uses an LX200 like computer command set with a few extensions to suit hand controller-less operation.
There's a telescope hand controller App for Android (free in the Google Play Store,) an option to control through a website (Smart Web Server,) and a dedicated physical hand controller (Smart Hand Controller.) Or, on a PC there's ASCOM and INDI drivers for control. These options allow you to setup and control OnStep using a wide range of software including my Sky Planetarium, Cartes du Ciel, Stellarium, SkySafari, KStars, PHD2, etc. You can see most of the control possibilities in the diagram below:
Also, please visit my StellarJourney.comsite for updates, links toOnStep resources, my other astronomy software, or to see someImages taken with the assistance of my OnStep operated mounts.
If you find OnStep useful and would like to show your appreciation and support please consider making asmall monetary donation. This keeps me motivated and helps cover expenses associated with my projects.
Hi guys, help here,
now that the S6 + mottors are working i want to add the wifi-module, i have a wemos d1 mini v3.0.0, and seems like i sucesfully uploaded the code to it (no changes to it at

Dear all,
I'm going crazy with the star alignment...
after the polar alignment made manually (seems quite good), I try to point something from stellarium or APT, the telescope goes in the correct

Desired Slew Rate = 2
Steps Per Worm Wheel Rotation = 0 (for now)
GR1 = 4
GR2 = 130 for Axis

I think what Andras means is to have a time compensation factor instead of yet another piece of hardware.
If a given controller is left running for, say, 24 hours, and an offset is observed, then a

You need to know a few things:
- What are the number of teeth on the worm wheel for each axis (RA and DEC)? This goes into GR2.
If this is an EQ3, then it can be many things, e.g. 130 RA, and 65
