I already had a Lynx EQmod cable so never bothered trying a normal USB. I even managed to update the mounts firmware through the EQMod cable.

Everything is connected to the PPB on the scope and then to a Startech USB to Ethernet box with RJ45 to the mini PC in the shed. The mini PC is connected to the house router via a Link powerline adapter. No issues with WiFi etc

Do you power the USB hub from the Pegasus or the distribution block?

OK so I run the power cable from shed to mount and fed into a banana plug type distributor. I then run a smaller cable from the banana plug box to the pegasus power box. Yes, I did solder the second cable to the plug that goes into the PPB but you could also just buy a crimping tool and some crimps. I avoided soldering for years and crimped everything but I've lately decided to tackle it again!

Thank you, very helpful. I have an idea now of how I want to run things. I'll most likely keep the Nevada at the house and run a 10m DC cable from PSU to the mount. Will probable use a Powerpole distribution block at the mount end and terminate the cable from the PSU with power pole connectors. Then, from the distribution block to Pegasus, one of these, although I should look around for a shorter one or make one myself.

Nothing wrong with 12v cable to the rig as long as you use good quality cable. I run a 2.5mm² 2 core cable from my shed to the mount over 10m. You just need to output more than 12v from the PSU. I use a Nevada linear supply and its set to output 13.8v. With everything running, mount, camera, focuser, dew straps it only drops down to 13.1 volts. I've seen more issues with people running out 240v and using inadequate 12v power bricks as they never put out more than 12v and under load they actually can drop causing issues.

Did you prepare your own cable?  How did you terminate the end at the mount? I am trying to avoid soldering if I can.

Hello,

I am in the process of setting up an imaging platform and would greatly appreciate some feedback on how to power the setup. My component list is as follows:

• GEM45 mount
• 107PHQ refractor (yet to arrive)
• IMX571 mono cam (yet to arrive)
• 50mm guide scope and QHY 290M guide cam
• Pegasus Pocket Powerbox Micro (yet to arrive)
• 7 port powered USB hub (yet to arrive)
• Pi with Astroberry

The platform would be setup around 10m away from the house, with the option to use an extension power lead from house to mount . I am trying to avoid power cabling as much as possible and have seen a few posts which suggest that I could use the Nevada PSW-30 as a single source to power the entire rig, with room for expansion. Which brings me to my questions:

1. How do I connect the Nevada to the Pegasus Powerbox? The Nevada has binding posts as output, while the Pegasus has a standard 2.1mm DC jack. Do I need to make my own power cable?

2. Once I have the above power connection sorted, what would be the ideal location (in terms of equipment safety from elements, power distribution etc) of the Nevada? Would it be better to either:

  a) Keep the Nevada (mounted inside some protective box) near the rig and run a 10m extension lead from the house?

b) Keep the Nevada in the house and run a 10m DC power cable from Nevada to the rig?

3. If I end up using all 4 of the DC power jacks from the Pegasus and I need more, how would I get this (assuming that I can't source power from the USB)?

4. In a set up like this, do I need to use Powerpole connectors at all? If yes, at which entry/exit points in the rig would I use them?

Thanks very much.

Felix
