I’m interested in what hardware and software you folks are using to do astrophotography from your home to your observatory or outside setup. Avoiding biting insects or cold conditions tend to make our hobby less stressful. In particular - what combinations of the two have you found to be the most compatible and consistent in operation.

MiniPC at the scope and second miniPC inside connected via ethernet.  Response is quite fast. I have a small LED display outside for doing PA and setup.  Then all else moves inside. 

Same for remote locations with second miniPC inside car.

I ran an ethernet cable out to my yard to avoid having to use wifi.

I use Splashtop Personal and ZeroTier (mostly as a backup). Been using Splashtop for almost 2 years now and couldn't recommend it more highly. I just started using ZeroTier as few weeks ago and its been great and is a very nice (and secure) option for local and remote access. Both Splashtop and ZeroTier work on pretty much any device you can think of.

If you're using Windows you can always just use RDP provided your imaging PC has a Pro version of windows but note that it isn't safe to us for access from outside your home network.

I use a mini pic at the mount for local control. It has RealVNC loaded which I can access from anywhere. I have an ipad that I can use while i'm outside for Polar alignment. Otherwise everything is remote control. 

Definitely use ethernet if at all possible. Much more reliable connectivity

Cheap J4125 NUC over wifi utilizing windows remote desktop.  Runs Nina without issue.  Just need to make sure you have decent wifi signal to your scope.  In my case the Ubiquiti U6-LR has no issue feeding both scopes in my backyard.

For imaging while away from home I just use TeamViewer to gain access to my desktop PC, which also connects to the scopes.

This is my setup. Runs off of 12v DC, or an AC charger, holds my Beelink Ryzen PC, powered USB hub 11 port, DC Step Up Converter 20V, small fuse box inside under the PC with lots of 12V DC outlets of every kind. There is an AC inverter in there just in case. The 12V battery has a Bluetooth battery alarm, the plastic box has a GPS receiver and DC power monitoring display on top. It uses a high gain 2.4Ghz directional antenna via WiFi adapter connected to the PC. This thing is my Swiss army knife. 

I connect to it via Remote Desktop, on my main PC, runs on all 3 of my monitors. PCs comes with Remote Desktop built in. When at a remote location, I'll setup a hotspot from my phone, and use my laptop from the car.   

This setup runs dual instances of NINA and PHD2. Been using it for about a year now. Cost about $375 to build, including the PC, and 40Ah of lithium batteries (12hr battery capacity), charger and everything. Worth every penny.

Beelink Ryzen PC,


I've been using this same PC and its been great. CPU on it is one of the most power efficient as well. 

The size of the PC makes it pretty easy to pop out and work with inside at times as well.

Thanks for all of the replies. I’ve been having connection issues with my observatory and I wanted to see what others are doing successfully.
‘My equipment is running well. N.I.N.A. is a great program and everything connects well … when I’m able to connect with the Mini PC in the Observatory.

From your replies I now know that my Mac in the house should be able to connect with the Mini PC out there. I just have to figure out what settings I have to change to get everything working. As strange as it may seem, I did have Microsoft Remote Desktop working for several weeks and then it just stopped working. I have an Ethernet cable but I can’t get it to connect. No luck with Apple’s Remote Desktop either. 

The frustrating part of all this is that at one point every thing worked.

Again, thanks for the feedback.

I assume you're connecting via wifi correct? Have you measured the signal strength out at your rig? If not you want to do so. Even if the signal is strong wifi is a very tricky protocol as it is susceptible to many different interference from especially if you have close neighbors.

When I'm imaging, my scope sits maybe 30 ft from the house, and I've placed a wifi extender near the scope (but inside the house). At the scope I have mounted a Mele Quiter3Q mini PC running Win11 Pro that connects to the mount, camera, etc and runs NINA and PHD2. The mini PC is connected to my wifi network. I use a laptop inside the house that's also connected to my wifi, and I use the laptop to remote into the mini PC using Microsoft Remote Desktop. Works great.

I have a mesh system in my remote setup. It’s better than an extender. I ethernet cable runs out to my roll away observatory and I have it connecting directly to my Mele Quieter 3 PC which is on my mount and also to a mesh unit that transmits a wifi signal but is connected to my network switch via a ethernet cable. I remote into that with either Windows Remote desktop, Google or Teamviewer. My wife is kind enough to roll the observatory off and on for me if I’m away.
When I’m at home I use Windows Remote desktop on my ipad. I regularly am away from home due to work and if the forecast is clear I  can remote in Via Teamviewer or the google remote. 

Your connection issues could be due to the wifi extender. A mesh is much better as the computer doesn’t have to jump to a new wifi network (yes its an extender but it is actually a new network). I mesh system is one continuous signal, or network. I have never had any connection issues with the mesh. I can walk out to my observatory and the wifi signal to my ipad doesn’t drop out.

I run a mini PC at the mount. I use RDP to control it. The observatory is mains powered. So I use 2 powerline ethernet adapters. WiFi drops to frequently to be useful.

Everything runs on the mini pc, and inside my house I use robocopy to automatically copy new fits files over to the processing PC to be integrated later.

I have a small switch in the observatory too. It is POE and powers a Reolink CCTV camera. Not so much for security, but for keeping an eye on it all during the night (it has IR built in). This also runs off the powerline ethernet adapter. (The trunk port actually runs over it, the mini PC is a simple access port into the switch)

This all sits in a corner cabinet. I only have to go out to shut the roof and power down.

You can see the mini PC on the vesa mount. The vesa mout is secured by tube rings around the pier. These are actually their to help dampen oscillatoratory vibrations. They do rather well, and serv as a mounting point for power and "stuff".

Hope that helps,

Another option is to use an ASIAIR Plus for control at the scope and a recent iPad for connection.  While not as fast as ethernet, it can work quite well with far fewer wires and gear needed.

I think I may have located the problem. I do have a Linksys Mesh system with one of the nodes in the observatory, so signal shouldn’t be a problem. I also have an Ethernet cable to it  but I’ve never been able to get it to connect. It’s been tested and is functional. I checked the IP address of the Mini PC but when I Pinged it I got no response. I retrieved thePC from the observatory and when carrying it back to the house it rattled. Some pieces appear to be loose on the inside. Not a good omen. I ordered a replacement and it will be here tomorrow. I chose one of the brands that some of you have been using successfully. Hopefully this will get me back into astroimaging.

Signal can most definitely still be an issue even with a mesh system if your nodes are too far apart. People tend to put them where they experience weak signal. This is a problem because if a node is receiving a week signal its going to put out a good signal. For this reason I still highly recommend  you test the strength of the signal coming from the house (with your obs nod unplugged) to judge its strength. If the signal is less than about -72db that is on the low end of decent. any lower is not an adequate signal. And again even if your signal strength is strong that doesn't mean you aren't being effected by interference.


Really the best thing you can do here is to get that ethernet cable going out to the obs working. If you do that you can not only hardwire your mesh node but you can also hardwire your imaging PC and that would make your life so much easier.

I have a Raspberry Pi 4 with Astroberry installed. The software is Ekos/Kstars. Have been using Ekos for 5 years now on several brands of SBC, but the RPi 4 with Astroberry is the most stable solution so far. Any crashes can generally be backtracked to hardware failure (usb cables eg). Until recently, the RPi got power from a MeanWell 5V power supply, 75 W. The mount and other hardware get power from a 12V 150W MeanWell supply. The RPi sits on top of my telescope, together with a Pegasus Astro PowerBox Advance for easy cable management. Until a few weeks ago I had diy distribution boxes for 5V and 12V, but now I've switched to the PowerBox advance, and got rid of the 5V supply. The only cables coming off my setup are a 12V power cable and an ethernet cable.
Astroberry uses vnc for remote control, and I can connect to the RPi from any web reader.

Hi Mossyback,

I use a MiniPC that is mounted on my fence and some custom cable for powering the equipment. An active USB cable is used to connect my scopes to the PC. I now have 5 scopes (only two are used simultanously) that are prepared with AF-motors (some are DIY), USB-Hubs, DIY Power controllers and guide scopes. The PC is on the fence, because I want to be quick when changing the scopes. Every accessory is mounted on these scopes and I just had to connect the power and USB cable… could not be faster. Everything is put on an EQ6-R Pro.

For a second setup on a NEQ6, I use an old Thinkpad X240 which is not the fastest machine anymore, but still able to control my second rig. It is placed in a case and then surrounded by a wooden box with a water proof top. It is outside for two years now and I didn't have any issues.

Both PCs are running NINA. Inside the house, I use another laptop with RDP. But my experience is a bit mixed. The laptop works fine without any issues for years now. The MiniPC on the fence seems to disaple RDP constantly when updating the anti virus software. So I had to include a Raspberry Pi as a KVM-controller to remotely activate RDP again. This is the most frustrating part of my observatory. I was not able to find the Windows settings, where I could prevent this to happen.

But beside these problems, my system seems to work very well for about two years now. Both PCs next to the scopes are not easily accessible with a real keyboard or monitor. So I use RDP even when I do some settings outside. This is the only time I use Wifi to connect to it. The MiniPC is setup as an access point using the Connectify-software. Inside the house, everything is done via ethernet cables that run out to the PCs to stay safe. I don't like wireless setups. They are slower and not reliable enough for my needs. My scopes are quite far away from the house.

I plan to build my own observatory in the near future. Currently, I just put two covers (Telegizmo 365s) on my rigs. A wheather box is warning me at night, If there is any rain or clouds detected.

Problem solved. Replaced the broken computer in the observatory with a MeLe Quieter 3Q mini PC. I’ve been able to connect with it using Microsoft Remote Desktop. I also have my Ethernet connection working. I’ve now started loading all the software programs into the new machine.

Clear skies to night! smile
