Stop laughing at my bracket Graham – it was a fence post bracket before I bent it into a Z shape and fixed to my ST80 focuser. Looks good Are you planning to release the source code? I needed a way to fix the device that was secure and simple. We have placed cookies on your device to help make this website better.

Arduino Ascom focuser Mark2 – DIY Astronomer – Stargazers Lounge

Thank you Mr Brown. Already have an account?

I’ve never used an Arduino but I’ve been itching to have a go. There are also some links to videos that show you how to create a driver. Sign in with Google.

Posted June 15, Found making the telescope focuser brackets the hardest bit – as I am not a “Graham” – wish I were. Totally worth having a go, for my C9. This can be used to track when you might need to refocus as the temperature changes.

Also need to test the focuser on Windows 7,10 as its running on Vista at the moment but it should be ok – 10 we shall see. I started by cutting a cardboard template then used that to cut out the cork mats. Sign In Sign Up.



The sketch is a modified version of the one I wrote for the mk1 device with the code for the switch and rotary encoder docus. The one downside is that the Robofocus controller is a bit on the expensive side.

Hopefully I will duy it done at the weekend. A shot of the rear of the cork block after some trimming. This was built using Visual Studio and you will need the Ascom platform 6. Important Information We have placed cookies on your device to help make this website better.

If you could do an idiots guide for getting an Arduino talking to Ascom it would be greatly appreciated. I wanted to turn it into an Ascom-driven device so I can use it remotely from my PC. The rotary encoder support was so I could manually focus the telescope. I ran the four wires from these two motor ports to the pins of a female DB9 connector. I did join the yahoo group but couldn’t figure their focuser out. This shows the cutout section that slides over the dovetail bar on the ota.

Already have an account? Ok so far so good – next I tried driving the focuser when attached to a Focuw ST80 using a direct shaft coupler – knock me down with a feather it works. Sign up for a new account in our community.


Posted March 15, The VS solution contains 3 projects: I intend to create a standard installer for my dit but I dont get much time to spend on it at the moment.

The biggest issue I have had is how to fix the focuser to the ota. Something like this hardware wise http: In my case I was most intrigued by this website:.

I need to try it when I am imaging planets or the Moon as that is where I thought manual control would be most beneficial. I have been using a Robofocus focus controller for many years now to control a Robofocus geared stepper motor on focud various imaging telescopes. I have added additional code so the nano can interface with the Ascom Driver.
