    Default Meade LXD75 with autoguiding trough PHD2



    Recently i bought a second hand Meade LXD75 to start with astrophotography. I am very happy with the scope and mount so far, and the results are pretty good.
    I had the opportunity to buy a QHY5R-II-C guiding camera and a 50 x 166mm guiding scope for a good price so now I am trying to make everything work with PHD2.

    I installed the following software:
    Meade autostart suite 5.5
    Ascom platform 6.4
    Ascom Meade classic driver
    Ascom new pulse driver
    PHD2

    I think I have most parts working now but some results vary and I don't get feedback within PHD2.

    In PHD2 i am using the Ascom POTH hub, and within there i use the I_Autostar 487 driver. This seem to work when I use the manual control trough the acsom driver. But when I use the manual control of PHD2 the mount does not give any feedback.
    I also don't see any correction feedback in the history graph of PHD.

    All the tests i have done so far are with stationary lights which should at least give some feedback.

    Am I doing something wrong or is this to expected until I am tracking real stars?

    Something is definitely wrong here, last winter I had a lxd75 mount and tried to autoguide with it , I did it everything to work with phd2 but I found the slop in the Ra was way too much to overcome, but it's worth a shot. I believe if I remember correctly I downloaded from ascom "Meade LX200 Classic and Autostar #494, #495, and #497" mount drivers" did not use the "poth"hub, that is certain.

    I have tried those, but had not feedback at all. Can you confirm that i should be able to move the mount with the build in manual controles of phd2?

    Honestly, I don't remember but I set everything up as described in a thread I found on meade 4m community.

    If you can't move the mount with the ASCOM manual control buttons (N, E, S, W), then ASCOM is not connected to your mount. This is almost always a driver problem or a COMM port assignment problem. First, go into device manager see which COMM port your mount is showing a connection to, make sure it matches the COMM port assignment in ASCOM. Then, if needed, search around for other Meade/Generic drivers and experiment with all of them. Once you can move the mount with the ASCOM manual buttons then you should be able to move along to the next step for autoguiding.

    Your screenshots of PHD 2 looks to be showing that nothing is connected (neither camera nor mount). And the ASCOM panel that shows the mount position looks to be the simulator numbers. Do the Alt and Az numbers shown on the screen even remotely match where your mount was pointed?

    Let me know.

    Cheers,

    The ting is, the ascom (N, E, S, W) software controller works fine, also the feedback is correct. The problem is that the PHD2 software controller within the PHD2 software does not react (tools --> manual guide).
    When I press connect, PHD2 also says that the controller is connected, and when I disconnect the RS232 cord I also get the message that it can not connect. So there is definitely a connection.
    I also tried to connect with PHD2 directly to the I_Autostar 487 and through Ascom POTH hub. Both drivers give the same result, except the POTH hub let's me control the mount with the ascom software controller while de direct driver has no way of manual control.

    But I also think it is a driver or related problem, today I am going to install windows7 32bit on my laptop to see if that works better than windows 10 64 bit. I have the feeling that I am close to get it working, and all the forum threads I can find on the internet tell me that I use the correct software.

    If there is anything else I should try, please let me know.
