Hi all, just thought I’d share my latest creation to further simplify the number of components in my setup.
So, my current rig requires 3 devices for my imaging session.
1. A computer to run kstars/ekos (I currently use the Asus tinker board)
2. A powered USB hub (because my USB3 cameras suck too much power and the Tinker box would not run them without additional power)
3. Astroberry focuser (running in server mode with a Raspberry Pi 0W) which connects to Asus tinker board via indiserver) to focus.
My mount connects to the Asus Tinker Board via Wifi. Eventhing is controller by remote desk topping.
My latest creation is the "ultimate" single box device which uses the current Raspberry Pi 4 (4G version) computer. It eliminates the Astroberry focuser running in server mode and the powered USB hub. Everything is inside a HighPi Rapsberry Pi 4 enclosure (see
I also installed a cooling fan and heat sinks to keep everything cool. Under full load I'm only seeing temperature of 59 degree C with ambient temp of about 26 degree C.
I have all the wiring for the Astroberry focuser which runs a DRV8825 motor controller connected to the Rpi4 GPIO. I also fitted a 12VDC to 5VDC 5Amp buck converter inside, which powers both the Rpi4 (i soldered the power supply directly to the RPi4 board, do this at your own risk!! see picture) and the Astroberry focuser.
I connect my Astroberry focuser to the motor using RJ12 plug.
And that's it. Everything runs beautifully and I reckon this is the ultimate mobile rig.
Lots of trial and error, mainly error, but in hindsight, it was easy!!!

I use C8SE with AVX. Pi4 with Astroberry, and 5GHz router for a faster communication, Celestron SkySync GPS, Shoestring with Motofocus autofocus, OAG with ASI120MM Mini (mono) as a guide camera, Celestron f/6.3 reducer, and Canon T3i as capture camera.
Also, I use Jackery Portable Power Station Explorer 240, 240Wh as the power source with passthrough capability, and finally, an IR IP camera for remote monitoring.

My semi-permanent setup on the garage roof.
(Mobile setup is here -
I keep the tripod/mount there most of the time covered with a DIY cover made out of tarp.
I put my imaging rig on whenever I feel like imaging and keep it there for a week or two.

I've been into this for 3 years now. Went to indi after 2 years. Jasem hot-swapped my driver and tested/ran my setup from the other side of the planet.
I'm fully remote from anywhere. I still swap back and forth. Pics are from my remote IP cam. = (

Hope some day I could make pictures like yours. Beautiful.
Could you give more detail on the AVX support+wheels+brakes+shoes seen on one of your telescope’s pictures ?
Is it custom made ? Is it possible to learn on the design/construction with more detail somewhere?
I am just building a wheeled support for my AVX in order to move it from my bedroom (its parking lot) to the terrace. So, your setup is very interesting to me.
