  1. Glad to hear more than I have got a clean sensor. Lars
  2. I too feel that a 64-bit installation is a must today. The downloading of the Canon EOS file speed up ramarkable, from 9 sec to 3, and a lot of other things to of course. I have done som updates of my setup: http://www.astrofriend.eu/astronomy/projects/project-kstars-raspberrypi5/01-project-kstars-raspberrypi5.html The only thing left now is to implement my special Custom Gear setup of EQMOD. Lars
  3. Thank for feedback. So interesting to see what much different ways there are to setup a Raspberry. I can't say it works all time, but most. The GPS is the most common problem, only use it when take the car out to remote dark places. At home it's connected to a LAN. Lars
  4. My RaspBerry Pi4 ages and I need one more RP. Now they sale the new Pi5 versions which is much faster. I bought one and it didn't cost much more than the older Pi4. But I had to chose the 4GB version because the 8GB was sold out. When doing this I want it setup with the new OS with 64-bit. I have read somewhere that KStars/Ekos isn't developed anymore in the 32-bit version, or at least not much. As usual it's much more complicated than I thought it to be. Mostly because I'm a Windows man. But I have good Linux friends 🙂 Here is my Raspberry Pi5 project: http://www.astrofriend.eu/astronomy/projects/project-kstars-raspberrypi5/01-project-kstars-raspberrypi5.html I got most of it to work but have problem with VNC, I add more information during the progress of this work. How many of you have the Raspberry Pi5 and 64-bit OS with KStars/Ekos ? Lars
  5. When looking at my old projects I noticed that I have a lot of readers on my project about the EQ6 mount. I have gone through the text and correct mistakes and moved out some of the pages to separate projects/tutorials. Here is the updated version: http://www.astrofriend.eu/astronomy/projects/project-eq6-dismantling-rebuilding/01-eq6-dismantling-rebuilding.html Let me know if there is something that is unclear and I try to complement the information. It works very well nowadays, both on Windows ASCOM and Linux KStar system. Lars
  6. After many years I have now my TS130 APO refractor up and running again. The new push pull focuser I designed and the motor focuser controller for INDI made it. One of the first test photos, it's taken from home with Bortle Class 9 environment. http://www.astrofriend.eu/astronomy/astronomy-photo/galaxies/m51/m51-galaxy.html It's very noisy but the focuser worked very well. Lars
  7. First outcast to add an off-axis guider to the filter wheel: http://www.astrofriend.eu/astronomy/projects/project-filter-wheel/08-project-filter-wheel.html Lars
  8. Added a lot of updates to the project. I have 3D-printed the wheel and chassi and it looks like something that could work. Project documentation: http://www.astrofriend.eu/astronomy/projects/project-filter-wheel/01-project-filter-wheel.html Lars
  9. When having a 3D-printer it's a lot of thoughts about everything that can be 3D-printed. If I buy a monochrome camera in the future there is a need of filters and a filter wheel. It's not very dificult to design it in 3D CAD, the problem is more, will the plastic material be good enough ? At least I get it exactly as I want it. Most people who do this buy a manual filter wheel and set a motor on it. Here I give it a try to do it all in the 3D-printer. My filter wheel project: http://www.astrofriend.eu/astronomy/projects/project-filter-wheel/01-project-filter-wheel.html As a driver for the filter wheel I will use the open source project myFilterWheel. Lars
  10. Hi, The last I did a couple of days ago was to replace the stepper motor with one with higher impedance. http://www.astrofriend.eu/astronomy/projects/project-motor-focus-driver/11-project-motor-focus-driver.html Lars
  11. Now when I almost finished the focuser project to my TS130 APO refractor there are a lot of small upgrades to do on the refractor and its peripherals. There are: Mechanical, USB hub, brackets, DC/DC converter etc. They all can be more practical, smaller and more energy efficient. To my help I have the 3D-printer. Here is my documentation of what I'm doing: http://www.astrofriend.eu/astronomy/projects/project-ts130-upgrade/01-project-ts130-upgrade.html I soon hope that I can get the telescope up on the mount with a clear sky. Lars
  12. Hi, Yes I read about all struggle people had with there old ASI120 cameras. My camera is not the mini as yours. But is there any difference in the electronics ? Now I'm waiting for a clear sky to do a real test how it behave. Lars
  13. I setting up a second astrophotography equipment, to make it practical I bought a second camera for auto guiding. It's a used ZWO ASI120mm with the old USB2. It will be used with a Raspberry which use Linux. Bad chosie because it didn't work with Linux and all say it's very complicated to get it to work correctly. I gave it a try and collected all information from INDI forum and others and got it to work. Here is my documentation if someone else has the same problem: http://www.astrofriend.eu/astronomy/projects/project-asi120mm-upgrade/01-project-asi120mm-upgrade.html Note, I havn't tested it under a clear sky yet. Lars
  14. Today I could do a load test of the focuser. I loaded it with 5 kg and there was no problem for the stepper motor to handle that load. Load test: http://www.astrofriend.eu/astronomy/projects/project-motor-focus-driver/10-project-motor-focus-driver.html Lars
  15. A good working motor focuser is important to get good quality photos. I make small improvements year after year. But now starting all over from the beginning and make a focuser that I have designed. It's a 3D-printed focuser and now I'm building the focuser controller based on the open source project MyFocuserPro2. Here is my project: http://www.astrofriend.eu/astronomy/projects/project-motor-focus-driver/01-project-motor-focus-driver.html Maybe I can do some desk test of it this week. Looks promising. Lars
