Raspberry Pi 3 + INDI -> Astro Imaging Automation

Recommended Posts

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 guys
      Can anyone identify which control box this is? Is it focusmaster? And does it run off robofocus driver in Indi lib as I cannot get a successful connection (in indi within ekos) 
      I bought a robofocus motor with this control box second hand. 
      I have faith with seller that hardware works as should. 
      I've tried other cables and USB ports too. The software (k stars) I use does do port search when connecting equipment.. 
       
      Any help appreciated 
      Wayne

      I have an EQ5 telescope mount which i use for astrophotography. I have modified it with a motorised RA axis using a bipolar stepper motor - my thread for the build is here .
      I want to expand the mount's tracking ability by motorising the DEC axis and using a guide scope/camera. I generally use the mount in fairly remote locations so would like to use a raspberry Pi for portability.
      I understand that I'll need to use a Raspberry Pi Camera Module for the guide camera. 
      The capability I want is:
      1. guide the mount along RA and DEC axes using a guide star as feedback
      2. track the mount using the RA axis only, and if possible continuously take 20-30 second exposures on the guide camera (this functionality is optional, but would assist in polar alignment of the mount)
      I don't want any GOTO capability. I am very new to RPi and need some help:
      - do I need to write code for this, or is there existing programming available for what I want to do?
      - is it possible to avoid the use of screens (in the field)? My preferred option would be to flick a switch to start and stop the guiding, with another switch for alignment mode (or something simple like this).
      - do I need to use any particular stepper motors/drivers for raspberry Pi? I'm using a bipolar stepper motor running quarter steps, with an A4988 stepper driver
      - is the RPi 3 Model B+ the unit I should buy?
      Thanks

      Starting my 1st IOT project. Since i've been an astrophotographer with no permanent setup, it makes sense to reduce the physical footprint (and the weight) of as many equipment as possible, as well as to do better cable management. I am soon going to start using Astroberry Pi server, an Ubuntu based suite for Astrophotography. Just purchased a Raspberry Pi 3B along with a 3.5" display for that. Lets see how it goes.

      £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.

      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.
