    EQMOD and Mount Limits

    Yes, you can manually position (slew) the mount anywhere you like - you're in full control and if you crash into the pier/trip that's your own fault. Limits are essentialy there to protect an unattended mount tracking into he mount/tripod.

    Couple of new issues for you to solve please

    Yes it will hit eventually. The problem was not that you had limits enabled, it was that you had left them the default (meridian). EQMOD RA limits are configurable. You could for instance slew off to your target so the dec axis gets positioned appropriately - then manually slew round in RA until the scope is about to hit and set the RA limit just that point. Then go back to your target, start imaging safe in the knowledge that EQMOD will track through the meridian but will stop tracking before any collision takes place.

    IOptron iEQ45 pro OR Skywatcher EQ6-R

    EQASCOM and EQMOD are the one and the same thing. EQMOD is the name of the community project that produced the EQMOD ASCOM Driver (EQASCOM). The EQMOD project has produced other software but by far the most widely used is the ASCOM driver which folks got into the habit of refering to as simply EQMOD. Whilst EQASCOM is at its core an ASCOM driver it also provides lots of other mount control functionality (Polar alignment tool, Sky model, gampead interface, GPS interface, PEC, Audio prompts etc.) that are not typical of other ASCOM mount drivers. If those features matter to you, and in all other respects the IOptron and EQ6r are matched, then the EQ6r may be a better choice. Chris.

    IOptron iEQ45 pro OR Skywatcher EQ6-R

    ASCOM drivers are what enable ASCOM capable software to (planetariums, guiding automation etc.) control specific hardware (mounts, cameras, focusers etc.). The uniqueness of each piece of hardware is abstracted into the driver allowing the the controlling software to use a common "language" when requesting services from the drivers. The drivers then interpret the ASCOM requests as mount specific commands. So, if you want to control your mount via ASCOM you will need a specific ASCOM driver written for your mount type. EQMOD is an ASCOM driver written specifically for skywatcher mounts.

    Eqmod finding com port problems

    Start EQMOD using the toolbox applicaiton that installs with EQMOD. The toolbox, unlike a lot of other ASCOM applicaitons, will not immediately close down EQMOD if connection to the mount fails - allowing you to see the error message EQMOD is most likely displaying.

    SGP - Platesolving nuisance

    Yes. Append on sync wil at a new point to your pointing model every time SGP syncs. This can be a pain when using plate solving at yo end up with clusters of closely grouped alignment points (where as alignment points really want to be space out). You have two options: 1. Stay with "append on sync" but set the proximity range filter so that only the last sync point added within a proxiity range is actually used by EQMOD (any other sync points within the proximity range are automatically deleted from the model). If you have a permanmently sited mount doing this allows you to have platesolving build up/refine that, as you visit different targets, will improve the accuracy of any "non platesolved" gotos you may subsequently make. 2. Change to "Dialogue Mode" (orginally this was the mode used for manual, dialog led alignment). With Dialogue mode any sync received by EQMOD only acts to shift its current point model to align with that sync point - no new points are added. This is the more traditional implementation of a sync. Each time a new sync is made the correction shifts in RA and DEC (shown as DxSA and DxSB in EQMOD) will be recalculated based only on the current sync/posiiton offset. Most folks just go the route od option 2 - probably beacuse this iswhat was settled upon by a consensus of opinion on the SGP support forum many years ago (but that's not to say there aren't folks sucessfully using option 1).

    What Constitutes Good Guiding?

    If you can't remeber to park then put some thought into how to setup a resynch encoders position (maybe some distant terrestrial object you can see with a reticule eyepeice or a physical indicator on the worm shaft (EQ6Pro have a flat on the end). All you then have to do do is create a custom park with the mount at the position and whenever you want to reysnc just move the mount there (manually or under EQMOD control), select the resync as you current park option and hit the resynch encoders button.

    Some questions about PEC in EQMOD

    If the files have been timestamped then that should be apparent in their filename. IF you're having trouble finding the files in widows explorer try changing the location they are stored (an AutoPEC config option) - Later windows version can be a bit fussy about giving folks direct access to the Program Files subdirectory that is the default.

    Some questions about PEC in EQMOD

    If you go onto the Periodic Error Correction tab of PECPRep you will see a plot of the "residual error" tha twould occur if using your filtered data to correct the actual data that was recorded. If you over filter the result can be a larger residual error. You don't have to get a perfectly repeatable trace on PECPreps Analysis - just aim for a curve that does a good job of fittig your raw data whilst ttaking out high frequency noise and non periodic elements. PECPRep will average the results of each cycle when it comes to build the single cycle PEC curve anyhow so any discrepenceiws in the individual cycles will be averaged out. Chris.

    Some questions about PEC in EQMOD

    Note that the options highlighed are not EQMOD AutoPEC - this is a low level interface to provide limited control of skywatcher's PPEC (on the mount's that support it)
  11. chrisshillito

    Some questions about PEC in EQMOD

    That isn't strictly correct. AutoPEC applies "generic" filters and doesn't have the range of functionality that PECPrep has (the idea was to keep AutoPec simple). For those who wish to have greater "manual" control over how their PEC file is created you can still pull the raw data file captured by AutoPEC for more advanced filtering and analysis.

    EQMOD Language

    With EQMOD not running use the toolbox app to open up your EQMOD setup screen. Under General options there is a language dropdown where you can select between "locale dependent" and "English". Note if you want the simulator to be in english to you'll have to do the same for the simulator setup. FYI the dll is named EQMODNL.dll and should be in the install directory along with eqmod.exe (probably something like Program Files(x86)/Common Files/ASCOM/Telescope) Chris.

    Imaging just keeps getting more complicated!

    Maybe PHD is running with admin rights then - the issue is that the "clients" of EQMOD are running with diffrent rights. Admin rights shouldn'd be necessary so long as everything is running at the same level. As for checking what rights things has that ma be dependent on which version of windos you're using. With windows 10 you can get the task manager "details" tab to show an "elevated" status of the apps runnig - if elevated they are runnig with admin rights. To try things out you can always right click on the app exe and "Run As administrator" and see if it makes any difference. If changing APT to run as admin sorts out the problem then that would imply the phd is already runnig as admin by default.

    Imaging just keeps getting more complicated!

    That will be because APT is running with different windows rights to the other applications using EQMOD. Install/Run all software with the same level of rights and you will only get one instance of EQMOD appearing. Chris.
