Notes on Celestron OAG Dimensions

Attached are some notes on the critical dimensions of the Celestron OAG should you decide at some point to make a design for it.

unhandled exception in focuser app

Hi Julien

There is a condition in the focuser app that will give an unhandled exception

The maximum target position of the focuser is 4000
Entering a number for the target position greater than 4000 will give an unhandled exception.

See below:

By the way, cool project. I made a focuser, but I made a no-solder version :)

Do you think I can be successful?

Hi Julien, I would love to give this project a go, but I have a few concerns mostly around my ability. I will need to modify the 3D files as I have an Antia focuser, OAG and filter draw, not the ZWO. I have zero skills in FreeCAD, but have decided to use Fusion 360 as I think that might be easier. I have already made some basic edits. The Antila is a touch bigger than the ZWO. I don't have a 3D printer, but will get the parts professionally printed. My next issue is the electronics where my knowledge is at an absolute zero. I would have to follow the information in here on GitHub verbatim. There would be no way for me to stray form the path. If I could not get the exact same components I would most likely be lost. However I would really like to see how far I can get. Would you be willing to help me if I get stuck?

Lastly should I hold on for the revised focuser with that battery, of should I crack on with the original design, as documented here on GitHub.

Thanks so much for sharing your wonderful project and knowledge here.

ULN2003A wrong way in fitzing schematic image

The ULN2003A is actually backwards in the schematic, which threw me for a loop for a few minutes.

ASCOM.DarkSkyGeek.OAGFocusDriver.dll

Hello, I'm not able to register to my windows 10 pc the ASCOM.DarkSkyGeek.OAGFocusDriver.dll.
I follow the steps indicated but always end with the same message. I even created the dll with visual studio whitout any troubles, but I try to register the dll and those messages appear:

RegAsm : warning RA0000 : Registering an unsigned assembly with /codebase can cause your assembly to interfere with other applications that may be installed on the same computer. The /codebase switch is intended to be used only with signed assemblies. Please give your assembly a strong name and re-register it.
RegAsm : error RA0000 : An error occurred inside the user defined Register/Unregister functions: System.TypeInitializationException: The type initializer for 'ASCOM.DarkSkyGeek.FilterWheelProxy' threw an exception. ---> System.FormatException: Input string was not in a correct format.

at ASCOM.DarkSkyGeek.FilterWheelProxy..cctor()

I looked at the RA0000 error on the net but this went in a spiral of wouldbe solutions...

Is there a simple solution to this issue ?

Best regards

Confused about hole sizes in base and cover

I'm confused about the hole sizes in the base and cover. The base holes are significantly smaller than the 4 mount holes in the cover. As the bolt/screw needs to go through the base into the cover, how is this supposed to work?

Thanks for any help. In the mean time I will use a feature in my slicer to fill in the cover holes and replace with smaller diameter holes.

Scops OAG: access to COM7 denied

Hello,
I know from the doc and the video, that the app should work fine with a Pegasus Astro "Scops" motorized OAG, too.
Unfortunately I have an issue here. Ascom Driver were registered without issues and I know that the OAG works on port COM7. When trying to connect to the device with the DarkSkyGeek app, I receive an error: "An error occured while connecting to the focuser".
I see the issue in the Ascom log, where it says that "access denied opening COM7" and also the Ascom Diagnostic tool says "accees to port COM7 got denied". Any ideas how I can fix this and find out more about the root cause?
Best,
Chris

Install ASCOM driver on my mini-pc

I just ran this focuser solution on my pc (windows 11) and it works perfectly. This is a really great solution. But when I load the software on the mini-PC (windows 11) at the telescope, NINA gives me an error. It's probably a trivial issue, but unfortunately I can't solve it.
The error is:
Retrieving the COM class factory for component with CLSID (xxxxxxx...) failed due to the following error : 80070002. The system cannot find the file specified. (exception from result:0x80070002)

What's the value of the capacitor on the PCB?

I couldn't find the value for the capacitor shown on the PCB schematics and final assembly anywhere.

The small disk capacitor on one of my ULN2003 driver boards measured at 0.01uf but I see you're using an electrolytic which I can only find starting at 0.1uf.

Which version of Arduino IDE to compile/upload sketch? Problem compiling with V2.3.0

When I try to compile the sketch I get the following error message in the unmodified sketch:

/ascom-oag-focuser-2/Arduino_Firmware/Arduino_Firmware.ino:17:16: error: 'constexpr const auto OK' redeclared as different kind of symbol
constexpr auto OK = "OK";

Which version of IDE do you compile with? What platform? (I'm on MAC).

Thanks for any help and this cool focuser.
