    Yes on the AM radio. Used one back in the CB radio days to find a power pole that was arcing.

    I currently (!) use 3 Tripp-Lite UPSs to run everything except heavy electric motor(s). We have usually good grid power but we get "blips" for usually less than a second.
    They can wreck electrical units so I keep the UPSs between expensive equipment and the grid. Just uncertain how clean of a wave they put out. A few years back every thing was "modified square wave" and that didn't work so well. Don't know what they do now.
    If I knew how to use my oscilloscope better I would take a look at the output.

    Could you send some photos of your setup?
    Are all 3 UPS units on the same electrical ground?

    Yes they are all plugged into the same circuit. I do have several circuits around the warm room I can plug into, but they all use the same breaker panel box.
    Which part would you like a picture(s) of?
    On the Tripp Lites, I have one for the AC lines up to the under the floor DC power supplies at the observatory. I have one to power the MaxDome box.
    I have one to power the two desktop computers and 3 monitors.
    But I have all three Tripp Lites plugged in to the same outlet via a surge protection box.

    Surge protection box? That's the UPS's job usually.

    How much juice do you need? I was expecting 1 UPS for the whole observatory; or maybe one for the PC and one for everything else.

    I get a bit obsessive......
    I don't really use all the power that I have....mostly.
    But I tried to run a vacuum cleaner in the observatory and it threw one of the Tripp Lites into overload.

    I pulled another 120v piece of Romex to run "heavy motors".

    Ouch. You can't put big motor appliances on a UPS like that!

    Yes indeed.
    Another thing that doesn't go over too well is a heat gun for heat shrink (and taking paint off). So now I have one circuit for just doing heavy stuff.

    The 3 Tripp Lites plugged into the Isobar.
    Just a computer sitting on top of them.
    Is this the picture you wanted?

    I was thinking more like a few pictures of the whole observatory, in case one of spotted something unusal... eg I've seen bad ground at the panel, or a pier that is not on the same ground as the building electrical. etc.

    I'll get on it.
    Might have a couple already.

    The warm room is done unless I have to fix something.
    Main computer is under the table on this end. You can see the Tripp Lites

    The power and data conduits go out and come up under the observatory
    Power conduit on the left, data conduit on the right. The under the floor power supplies are in the louvered box
    [​IMG]


    The power wires come up from the floor (in the flex conduit) and go into the MaxDome boxes.
    Also the new Romex run goes up to the box closest to the floor to juice the dome motor.
    There's close up pictures of the Maxdome boxes in the "Run away dome" thread
    [​IMG]

    The data wires and DCV wires come up inside the steel pier.
    The DCV wires come out to the barrier strips mounted on the plywood piece mounted on the pier.
    The USB extension box is the one with the green face on the plywood plate. Also RS 232 runs etc.

    If I can answer questions, ask.

    Hi Greg,
    What are the items 1,2,3 I've highlighted here?
    PierCH.png
    1 - thick black cable
    2 - black box
    3 - white box

    and where's the power supplies for the Mount, Camera, etc?

    1) Power in a split loom cable going to the RCOS controller box (12vdc).
    2) RCOS telescope control box (focus, rotator, fan control etc)
    3) Space heater for when it gets real cold outside and I want to work on things. Don't use it too much. It's connected to the new Romex 120vac run

    Everything plugged in to the 4 plugin box on the wall is 120vac device that is the direct run (no Tripp Lite Box) to the breaker panel in the warm room.

    There are 2 power supply barrier strips that supply 12vdc and 24vdc.
    The 12vdc barrier strip is on the far upper right on the plywood plate and has a sort of gray looking plastic cover over it.
    The 24vdc barrier strip is on the bottom of the plywood plate (next to the green Icron box) and supplies the Icron USB extender box and I have a temporary run to the FLI camera which will go away when the Sbig camera gets back.
    The mount has a 48vdc power supply and it only runs to the mount. That PS is located down in the power supply box under the floor.

    Just thought I would check in and see if you guys have found anything with the camera?

    Despite a lot of time and effort on Tim's part, nothing was found. The camera works just fine.

    What ever happened between when it left here and came back, it sure looks better now.

    It was full of stale old photons, so @Tim dumped them in the recycling bin, and then we ran it through the car wash a couple times. ;)

    OMG
    It was the cable that hooks the STX guider to the camera.
    As I reassembled it I took some quickie exposures.
    Camera worked fine.
    CFW worked fine.
    When it came to hooking up the STX autoguider it went back to disaster. Changed out the little HDMI cable to one I had and it worked fine.

    OMG, classic. Those cables really can cause a lot of not-so-obvious problems. And of course we'd never find it because the problem was outside the camera. The biggest problems happen when you end up with a cheapo cable that doesn't have shield. Such things should never exist... but do.

    Good find!
