  1. Arduino Sky Quality Meter - working!

    If you go to the sourceforge repo and dig inside the Documentation : https://sourceforge.net/projects/arduinomysqmskyqualitymeter/files/mySQMPRO/Documentation/ The "mySQMPRO.pdf" has all the build instruction (multiple schematics, ...). You can also find the Schematics in https://sourceforge.net/projects/arduinomysqmskyqualitymeter/files/mySQMPRO/Schematic and Layout/ Rodolphe
  2. So here is my first test with the Atik 16200 mono. The imaging condition are not optimal as I image in my front yard, next to a street light that uses broadband LED, I also have a few power lines, phone, other cables ... but there it is : https://rti-zone.org/astro/dso/m27/M27_2017_09_23.png You can get the imaging details on this page : https://rti-zone.org/astro_dso.php (first one on the page ) Rodolphe
  3. Pi3 Replacement

    Good point Nick. I have one here mostly for dev but I understand your concern regarding fan vibration and thermal throttled. Rodolphe
  4. Pi3 Replacement

    If you need more power that the C2, the ODROID-XU4 has gigabit ethernet and usb3 and more raw power.
  5. Arduino Ascom focuser Mark2

    I would think that sourceforge would have multiple data center, dually powered rack with different power rail, and announce their IP space through different tier 1 ISP via BGP .. with all the adds and other crap they are putting on their page these days .. Rodolphe

    Looks like the sourceforge page is no longer there : https://sourceforge.net/projects/arduinoascomfocuser/ This returns a 404 !!
  7. Open source X2 plugins for TheSkyX

    I've posted a few recent update to some plugin : - MaxDome II : I fixed the calibration and Sync. I now have a MaxDome II card for testing so this is a lot easier to debug (I'll have to return it at some point to the nice person lending it to me). - NexDome : I fixed a few bugs and also fixed a few issues that showed up with the new NexDome firmware (1.10). Latter I'll add a few things to the settings dialog for the few new commands of the new firmware. Rodolphe
  8. Arduino Help - convert to hex

    char buffer[10]; snprintf(buffer, 10, "C: %02X#", tempC); Serial.println(buffer);
  9. The NexDome code on the Arduino only does what you would call slaving, AKA it expect a GOTO command from the computer to move to a specific position and then stops. So the software sends position update (slaved to the mount/telescope) to the controller to keep the slit aligned with the telescope. Most dome control system work like this and wait for position update command to move and do not move by themselves. As you said, the difficulty on constant tracking is getting the speed right. Rodolphe
  10. Feel free to ask questions. Based on your picture above you already have a stepper controller with a big stepper. The NexDome system uses an Arduino Leonardo to drive the stepper controller via ASCOM (or a native X2 plugin if you're using TheSkyX Pro). I wrote the X2 plugin for TheSkyX Pro and built a test rig with the code from the link above to test the plugin. This has been used by a few people directly with the original NexDome but also with their own dome just using the original code of the NexDome controller and a stepper controller (the one you have is fine and will work). I can go in more detail if you want . The advantages, all open source and all open hardware Rodolphe
  11. As you're already using a stepper motor you might want to look at the NexDome sketch and ASCOM driver : https://github.com/grozzie2/NexDome You might need to change a few values in the sketch to match your gearing. You can then control it via anything that can talk ASCOM and control a dome. Rodolphe

    thanks guys.
  13. 2017 Eclipse from Oregon

    I was lucky to have family not far from the path of totality. So we drove for about an hour north from their place to Corvallis and I was able to see my first total solar eclipse. I followed advices from here and other forum to not take a telescope but just a camera an not worry to much about taking picture and just enjoy. Best advice EVER !!! I set some sequence on my canon remote, press the button and walked away from it And yea .. ECLIPSE !!! WOW ... speechless. Bonus.. I got some picture : https://rti-zone.org/astro_eclipse_2017.php I even manage to do a small animation : https://rti-zone.org/files/animation.gif Rodolphe
  14. I've written a bunch of X2 plugin for various devices for TheSkyX. Some people might be interested so I though I'll drop a note here. I usually make them cross platform when possible (which has been the case so far for all of them) so they work on OS X, Windows, Ubuntu and Raspberry Pi : https://rti-zone.org/macosx_x2filterwheel_plugins.php https://rti-zone.org/macosx_x2dome_plugins.php https://rti-zone.org/macosx_x2mount_plugins.php https://rti-zone.org/macosx_x2focuser_plugins.php I hope someone finds these useful. Regards, Rodolphe
  15. Arduino Ascom focuser Mark2

    I just wanted to let people know that I wrote a focuser X2 plugin for TheSkyX (OS X, Windows, Ubuntu and RPI are supported) for the AAF2. If you're interested you can find it there : https://rti-zone.org/macosx_x2focuser_plugins.php Regards, Rodolphe
