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, thank you all for the replies.
I understand the "reverse wedge" or align RA to zenith thing, but that practically disrupts the possibility to use the EQ mount for other "regular" things during the

Hi,
Is it possible to configure an ASCOM driver, so two focusers can be used at the same time - like for example in Maxim DL, where two ASCOM focusers can be connected?
I tried connecting first by

I think I may found what is the problem here.
First of all, you need to check values set in SWS (advanced axis config) because they will took over. To me, it looks like values set by config.h are not

Yes. Both of those are set. I am navigating the entire sky, except for that area under the pole.
Good idea. I will see what alternate program I can download.
Thanks,
Bob

If you are sure this is just to prevent switch stuck and not due to some hardware limitations (timer resolution, etc), I could increase this value because I don't use switches. I don't get it why

This is to prevent a stuck switch from driving the mount in circles. It forces you to let off the switch and then re-apply. It's a safety thing. I am sure the Manual Guide command is the same

Henk,
Get a schematic or specifications to make sure you can plug in 24V. I am using a MaxESP and they come with switching buck regulators. They drop the voltage down to 5V and take 35V or more on

Patrizio,
Rotate your RA axis to the vertical and you're all set. Or get a Dob.
Once I did the reverse. I had an iOptron cube, but the older alt/az only model. I just told it I was at the North

Hi All,
I am in the process of integrating my Onstep with my Losmandy. So far so good, with a 10:1 planetary &24V, I can achieve a decent 2deg/sec. I also have it running "goto"s from Sky Safari on

Another thought. Within the EQ mount restrictions i have no idea if the guiding port controls would give you the correct directions locally or if they set to move reasonable distances.?

This may or may not be what you are trying to do.
I have just started used Stellarium to control Onstep via the usb and using lx200 mode or ascom.
I am new to all this so other progs may do it as

Hi, maybe it's a stupid question, but is it possible to just be stupid and simulate the Alt/Azm movement in Equatorial mounts?
So when you press "N" on the SHC, instead of going "N" and move the DEC

You cannot flash the STM32 module from the microUSB on the module itself.
You MUST flash it through the CP2102 module on the PCB.
And there must be power applied, and the Flash/Run switch has to be

Thanks Drew and Howard for pointing me to the right place and for the explanation, now I see it and it makes sense. My bad, spent time searching on the forum and didn't check properly all the details
