I connect my mount to PHD2 using ASCOM and most nights I have the error "Star did not move enough" as well as "Suspicious blah blah, axis may not be perpendicular". This does not happen when I connect the mount via ST4 cable. I read somewhere that I can do a Calibration Sanity Check in PHD2. I am however unable to find that function in the software. Is it some pop up feature or does it have a location in the settings/brain icon?

Any help will be highly appreciated.

Please post the guide log with the calibration causing a problem. You can find them from the help menu option to open the log files folder.

When you swap between on-camera (ST4) & Ascom control, have you re-configured PHD2 in the connect equipment settings ?   If everything else is the same i.e. same camera, guide scope etc., then you calibrate by selecting looping, click on a likely target, then hold down the shift key while clicking on guiding. This will force a re-calibration.

Hi, did you also increase the ra rate and dec rate value under ascom pulseguide settings?  It's recommended to increase   to about 0.5.

If you move the mount with the on screen handset North just before you calibrate it takes the backlash out of the DEC, otherwise the software is trying to move the star and it can't so it gives up..click on N until it moves the star,then callibrate..hope it helps

      Hi All!

      I have guiding problem with the following guider setup: 9x50 finder + ZWO ASI 120mm mini + PHD2.
      The imaging scope is a 6' newtonian + canon dslr on a HEQ5, driven by a laptop via diy EQDIR cable.
      When the mount is set up and running correctly, polar aligned and all... I connect the guider camera
      and mount with phd2. All nice and easy, I run a calibration, then it starts to guide. All seems ok.

      Then I am starting to take pictures. The first seems OK, then the second have the star trails...
      I check phd2 and there is a message: the camera (ASI) did not take a picture for "xy" seconds so it is disconnected.
      Grrr.... I reconnect try to set up a longer period for "xy" in the settings as mentioned in the message.
      And all the same again and again. Whatever I add for connection timeout for the camera, it just reaches that
      and disconnect the camera.
      PHD + philips toucam has worked for me flowlessly. I changed to PHD2 because I gave myself a birthday present,
      the little ZWO camera. (and PHD did not recognize it)
      Do you have any idea what can be the problem? I will contact PHD2 help also, but maybe somebody had already
      the same problem and figured out how to overcome. I am almost sure I make some dumb mistake in the PHD2
      software settings, however I tried to change only what was needed.

      I have recently bought a Orion Starshoot Autoguider. I downloaded phd 2, eqmod and ascom stuff. After a small research I found out my mount (exos 2 gt) doesn't support computer acces without firmware upgrade and fancy cables but I have the st4 port so it shouldn't be a problem. In phd I choose camera as Starshoot Autoguider and mount On-Camera. Aux mount and AO are both none. My wiring is one cable to pc from camera and another to st4 port from camera. When I started looping I selected the star with no problem. I choosed the one star alignment option from my hand controller and after centering the Archturus in the middle of view I pressed ok and it was successfull. I started guiding and after a while I get the error: RA calibration failed star didn't move enough.

      Ok, so this is a really annoying bug / problem that I have with my setup:
      From time to time, in non regular intervals the image my guiding cam (ZWO ASI120) send seems to get flipped / mirrored or looks like it's from a completely different patch of sky.
      When I'm paying attention to the guide images I can clearly see that the image seems to be flipped in some way.
      It only happens for 1 frame PHD send a warning ( No star found / Star lost Mass changed) and after that everything is fine again. My gear is all connected to a single USB3 Hub which then runs via powered USB3 cable to my Pc.
      I'm not binning and have the noise reduction off (though PHD might got hickups while processing) but it still happens. Sometimes there are minutes between two events sometimes it happens 5 times in a row.
      It also seems like it's only happening during guiding, I haven't seen it happen during calibration yet...
       
      I'm completely clueless what's happening or how to get rid of it, any help / idea is greatly appreciated.

      Hi Guys, hoping someone can help me with the guiding issues Iv'e been having. First of all my setup is:
      Explore Scientific ED80 Triplet  Skywatcher EQ5 mount with synscan  Orion mini 50mm guide scope Altair GPCAM2 AR0130 Mono (as the guide camera) I did my polar alignment and 3-star alignment, which was spot on. So I set up the GPCAM2 and opened PHD2 where I selected "Altair Camera" and "On-Camera". It was all in focus, kept it on the default settings and I selected "auto select star", then it said I was guiding (I can hear the mount making small adjustments). A message popped up saying I needed to increase the max RA duration, then I needed to increase the max DEC duration, which I did gradually by 1000ms each time the message appeared. Still no progress.
      So I restarted the process with the max RA and DEC duration as 8000ms and it said I needed to eliminate the source of the problems.
      (I HAVE ATTACHED IMAGES OF THIS)
       
      I'm not sure why it not working and if I'm doing something wrong. But if someone knows where I'm going wrong, or has any advise it will be greatly appreciated!

      Oh and just let me know if you need any more info, because Iv'e probably missed something out. 
      Thanks again ?
