Hey guys, I recently found out about INDI and Ekos and was curious to see how well it worked (check it out here). I had a raspberry Pi collecting dust and after a couple minor setup steps, my equipment was recognized and connected. My mount, DSLR, shutter release serial cable, and guide camera all connect directly to the Raspberry Pi. I then connect to the Pi from my mac laptop using SSH and the Virtual Machine provided by http://www.indilib.org/. The nice thing about the PI is that it uses little power (about 0.5 amps at 5v), has 4 usb ports, and has built in wifi. I picked up a usb battery bank for the Pi and threw the two into a project box. I'm fairly sure the Pi would run 20 - 40 hours on this small battery alone. Anyways, I've seen a couple posts touching on this subject and thought I should share my efforts as I'm quite excited about it. It seems like it will perform better than my previous setup. My previous setup consisted of an intel compute stick, small usb hub, 12v battery with a 5v converter, and an additional windows laptop to control it all. I would connect all my gear to the stick through the usb hub. In order to get everything going, I'd remote desktop into the compute stick through my windows laptop. This worked ok, but the compute stick (running windows) was unreliable, there were a number of imaging sessions where it decided it would be best to install an update for half an hour. Other times, it refused to auto connect to the wifi hotspot without logging in, meaning I could not remote desktop into it and would need to connect a screen. Eventually, I tried using a LattePanda board as well but had similar experiences due to Windows 10. Regardless, I do recommend the LattePanda for windows applications, it is a slightly stronger board than the Pi and has an Arduino built in but unfortunately is not too great at running linux yet.

Hi. In preperation for a remote box-observatory i have been setting up a pc for telescope controll and more. I now have Kubuntu working with a ssh tunnel and headless vnc setup. KStars is installed with all necesarry drivers for my celestron avx, eos 550d and orion autoguider. Everything starts up in KStars and i have controll over all the exuiptment, except! The issue. 1. When slewing to an object using the nextstar hc on the mount: Recticle in KStars moves in the same path as the telescope, and ends up at desired target. 2. When slewing to a RA/DEC coordinate in INDI control panel -> Eq.Coordinates: Recticle moves as excpected and ends up on target. 3. When selecting a target in KStars gui, right clicking and selecting slew or track in mounts context menu: All kinds of craisyness.... The recticle moves erratic. Sometimes to high in the sky, and sometimes down in the ground. At one point i ended with the counterweight bar straight up and the scope pointing more or less at polaris, when telling it to slew to the zenith. The strange thing is that the recticle in KStars is pointing where the teleskope is pointing. So KStars "knows" that it's not pointing the scope at the target i selected, but it keeps on going. I was thinking it could be some time-site issue, but the t-s is set up in INDI control panel. Using INDI to slew manually, everything works as expected. Not 100% sure how the sync option works in KStars. Could i have synced to some random place in the sky and "un"calibrated KStars? Don't know how to undo it if that's the case. New to KStars and INDI. Hope someone can help with this issue. Magnus.
£130 Ono ! Will calculate postage when sale agreed but I can't see it being more than £10 with royal mail Stellarmate imaging astrophotography computer. Based on raspberry pi . Comes with upgraded 32gb card rather than the standard 16gb. Included in box is hdmi cable and usb cable with power switch. This was an early Christmas present but is turning into a project I just don't have the time for. Works with anything that has an indi driver. https://www.stellarmate.com It's like the zwo ASI air ...but can be used with other equipment including zwo. Please note if you have Altair cameras the driver is still in development.
