Synscan power supply wrong figures in manual?

Recommended Posts

I recently purchased a EQ5 mount with synscan. But rather then use the car adaptor running though a 3 pin convertor i bought a 12v 500mA DC power supply. The back of the manual states it requires 100mA (see image). So here i am thinking great this will do. Wrong. Its enough to start the hand controller and go through all the set up but it doesnt seem to move any motors. This being my first attempt i wasnt sure if i was doing something wrong. Did the brakes need releasing? - No. are the cables going to the right sockets? - Yes. After much head scratching i went back to to start and used the supplied 12v car style plus in a convertor i had. Sure enough it all worked perfectly. okay went back to my 500mA and nope nothing worked. After searching the house for a 12v 1A DC supply with the correct plug and trying that, Sure enough it all works fine. Have they simply missed a '0' off the manual or am i missing something else here? Tomorrow i'll probably go an exchange it for this 12V 1000mA Power supply. I'll let you know how i fair. And for anyone checking for power supplies (Like i did) your looking for a 5.5mm x 2.1mm power tip to for the unit.

Yes I remember going through two different adaptors before finding a 1200mA 12V supply worked. You know it works when you hear that click followed by the beep from the hand controller.

Perhaps the manual is referring to the amperage required to power the hand controller alone, a useless number since the motors require at least 1A when slewing at full speed.

The voltage and amperes in the photo only refer to the requirements for updating the handsets firmware. The mounts requires  11-15v dc with a continuous current of 2 amps (more is better) to ensure it functions properly.

Thats handy to know. Im not great on electronics but Amp wise it will only take what it requires? So if i was to get 3000mA id not damage the system?

Yep, I use 10\20 amp supplies (useful for powering cameras etc.) with no ill effects.

That psu should be ok.  The minimum requirements for a psu are 12v dc with a continuous regulated output of 2 amps.

Couldnt get anything closer then 1A today the 1.5 was a detachable end with different sizes. But as its outside im not willing to risk to many connections in the system.

But have tried it on the set-up and it works. But will be searching works psu stock for a compatable one with more Amps.

1.5 amps might work for a short while but if the mount tries to draw more current than the psu can supply then you will get problems.

      Hi guys,
      With new mount and upgraded scope features, now looking to venture into imaging.
      Before I start, I'm not looking to get feedback on polar alignment, mono guidecam, better imaging cameras, etc; this is more a 'dummies guide' setup discussion! I'm not expecting to get great images at this stage, just more the options available, getting over some issues, so that I can jump outside on a clear night with an ideal, foolproof(!), setup for either imaging or visual as time would permit and what may work best for me. As you may guess from the topic name, I'm a mac user (Macbook Pro) and would rather keep to this if possible (whilst I do have Windows (and Ubuntu) via parallels, I'd rather not use these).
      I've got a setup which has worked well for visual, and obviously want to have a couple of 'staple' setups that I can use depending on expectations of night observing or imaging. So far, the best one for me has been the Skywatcher Wifi Synscan controller, which has worked a treat with my Android phone - I use the Synscan app to complete alignment and GOTO stars/planets/DSO etc, or Stellarium_plus after completing alignment. This removes the need for the Synscan Handset and any USB cables to the mount altogether. But I don't know if this will work for guiding.
      That then brings me to my issue on mac - connecting USB(A) between Macbook and Handset, I've attempted to control the mount through Stellarium. Trying each of the available connections (/dev/tty.usbsetial-1420, /dev/cu.usbsetial-1420, and just for sake of it, the /dev/tty.Bluetooth-Incoming-Port and /dev/cu.Bluetooth-Incoming-Port) in the dropdown menu under DeviceSettings/SerialPort, I cannot get the mount to connect (well, more like selecting the telescope and clicking the "Start" on the TelescopeControl just results in the spinning icon and I have to Force-Quit Stellarium and start again with the same result each time. Annoyingly (for fellow mac users!), Parallels/Windows/Stellarium connects and controls the mount fine! As the mount is the newer "pro" type, I also have a USB connection directly under the hand-controller RJ45 and AutoGuider ST4 sockets, but using this still results in the same issue. Another issue I have seen is that when I unplug the USB from the computer when connected to the handset, the date on the controller jumps significantly - for example, last night at ~23:30, I was transported through the local wormhole galaxy to Jan 2048 according to Synscan! Obviously unplugging isn't going to happen during a genuine session, but just wondering if this is a possible issue somewhere?!
      Any other mac users connecting USB directly to the SW 'Pro' mounts?
      Software wise, would folks generally suggest steering away from Stellarium towards KStars or SkySafari(Plus) for controlling the mount?
      Can the Wifi dongle be used for controlling mount from computer (any OS) or do I need to go USB either to handset or directly to mount?
      Is there an issue in using Mac USB to the telescope compared to 'straight' Windows (i.e. PC/laptop with Windows instead of virtual)?
      Anyway, back to topic... I've a Nikon DSLR to use for primary camera at this stage, which would be triggered independently from guiding software. PHD2 is my hopeful choice of guiding software (is EKOS with KStars similar?), with T7C guide-camera on 240mm f/4 guidescope, and at this stage, I can confirm PHD2 at least connects to the camera on OS-X. There is an ST4 port on the camera, but having read several topics, I think I want to pulse-guide directly - is this correct or is ST4 best for this setup? This sorta comes back to software and connections - my understanding is one of the following cable setups for guiding (as a minimum) :
      Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => SynscanHandset => AZEQ6
      Guiding-camera => USB(A) => Macbook => PHD2 => USB(A) => AZEQ6
      Guiding-camera => USB(A) => Macbook => PHD2 => Wifi => SynscaWifi Adapter on AZEQ6
      [using ST4: ST4_on_AZEQ6 => Guiding-camera => USB(A) => Macbook => PHD2] (no additional connections needed if ST4 is used)
      Additionally, I'd like to use an observatory package, say Stellarium/KStars/SkySafari, to select objects and drive the mount, then use guiding software to keep good 'tracking'.
      Where in this train does EQMac fit in, or when is it used?
      What about the 2019 addition to EQMod (ASCOM Alpaca)? Can this be used or is it already in other packages?!
      For Windows users, how does EQMod fit in (if I go down route of getting Windows laptop for controlling things, is the setup similar to above?
      There may be bits in the above that repeat, and for that, I'm sorry, just want to get across the message that I'm new to the guiding but haven't quite settled down into the software/hardware I'm expecting to use for 'goto' and 'guiding'
      TLDR:
      For a mac user, what setup and software are folks using for guiding and observatory softwares for the newer USB-on-mount 'AZEQ6/EQ6-R Pro' mounts from SW?

      Hi
      I am looking for help and advice on my SynScan EQ5 pro problem which i am struggling with. Everything was working fine and as expected. I have never updated the firmware and thought while i had everything connected i would update the Hand Controller and the skywatcher WiFi dongle. 
      Everything updated first time without issue and i was pleased to be up to date. However i loaded SynScan app on the pc which connected fine through the handset and USB/Serial adaptor cable. I clicked on the movement arrows and nothing happened, i then went in to a random 1 star alignment and again no response from the motors. 
      I powered off again and instead of the PC i tried the hand controller, i tried a 1 star alignment and the hand controller was displaying the slewing but again no response from the motors. in panic i then did the same with the WiFi dongle and phone app, same thing the software is showing movement but the scope remains still. 
      Knowing all was well prior to firmware updates i reverted back to the previous firmware version and no difference, i tried it again in Lo mode and still nothing. I then noticed a firmware update for the Motor Control so thought i had nothing to loose i updated the Motor Control firmware and again no sign of life from the Motors. I have swapped the cables around, checked that they are all inserted correctly, the power is from mains not battery and the power source is plugged in to a a Power Filter and Surge protector. 
      I have little experience of circuit board electronics, i was struggling to find similar experiences online other than voltage issues due to batteries which is not the case. I have opened it up and no obvious loose cables of solder loose, but this was straight after the firmware update which seemed to have installed and updated very smoothly no crashes etc. 
      Any help would be really appreciated.

      Hello all,
      First post since my initial hello message due to a lot of cloudy nights and a small wait until I could afford my very entry level camera. I would like to apologise straight away for my lack of knowledge and the poor quality of my images. The framing is terrible and they're out of focus, but I'm also completely over the moon with them. I'm very eager for you guys to rip them apart and tell me all the ways I went wrong but I will always love these 4 images as they are the very first successful AP images I've taken
      My equipment is as follows
      skywatcher 150pds on a eq3-2 pro synscan mount
      Polar scope
      Canon 2000d
      Super coma corrector
      I have tuned the motor drives for the mount but haven't stripped down and cleaned and greased the mount itself yet but plan to. Also plan to upgrade to a heq5 Pro asap. I have no guiding other then synscan. Again something else I hope to change as soon as I can but for now its an oppurtunity to learn.
      None of the images are stacked, they're single 30 sec exposures. I very slightly adjusted the raw files by placing a slight s curve on the linear channel but will leave any further processing if I bother until after a good nights sleep. I've included both the before and after image.
      The first image is just of vega, I took it while star aligning. A awful pic for many reasons, especially the flare coming from the star, but my first so will keep it for sentimental reasons. The second I was very happy to catch some light from the ring nebula, and was equally happy to catch the dumbell nebula a little. The fourth is the globular cluster. All really bad framing but was suprised to catch the nebula on just a 30 sec exp with my light pollution. 
      Can't wait for your ideas,suggestions and criticisms. My apologies for a very long post but feel very hyped up even after such awful results.
      Many thanks and clear skies
      Matt

      A used RA motor drive kit for the Skywatcher EQ-5 manual mount. Contains everything you need to upgrade your manual mount to give tracking in RA. (Needs 4x dry cells, not included).
      Price: £45.  Postage £3. Or you can arrange to collect it in person (social distancing rules will apply). Or you can get your own courier to collect it.
      Also available is a 6 volt sealed lead acid battery that will power the kit instead of the 4x dry cells, with 6 volt charger. £10.  This is collection only as the postal services don't like used batteries with wires attached. (can't think why 😁).
      Also advertised elsewhere.
