Hi, I'm new to this whole auto guiding thing so bare with me!
So I have a iOptron SkyGuider Pro with a WO Zenithstar 61 and recently bought a ZWO ASI120MM Mini and guide scope to have a go at auto guiding. I followed tutorials online step by step (installing drivers, and changing the settings in PHD etc.) and managed to connect the camera and mount in PHD, start looping exposures and select a star. But when I start the calibration, it counts to 'west step 61' and comes up with "RA Calibration Failed: star did not move enough"
I have tried reinstalling all drivers/software, using a different laptop and solutions other people have found do not help. Guide scope is focused and it's not trying to track a hot pixel.
The star is supposed to move up and down as the mount moves during the calibration although nothing happens. So this makes me think there is something wrong with the mount or the ST4 cable from the camera to the mount. Cable securely clicks into both ends. I have heard the term "backlash" with mounts and not sure if this could be the cause? Not sure what this means or if this is possible with a star tracker?
I can't seem to manually control the mount in PHD although I'm not sure what I'm doing. I can however, manually press the buttons on the mount itself and it moves fine.
I've attached pictures of my setup along with the 'Guide Log' that people often ask for - PHD2_GuideLog_2021-08-23_225305.txt
(Also, the total weight on the mount is 4.7kg and the max payload is 5kg for imaging so this should be fine?)
Any Ideas? Let me know if you guys need anything else.

My synscan V3 handset is having issues in the goto settings, for example, it may be over 10 degrees out in azimuth and a few degrees out by altitude. For troubleshooting purposes and to save you from asking unnecessary questions, I have tried different locations and made comparisons, I have also tested multiple different targets. My location, date and time are also correct and to make sure, I have tried different variables to see if there is a difference but there is not, the handset is still out. I should also let you know that the difference between the real value and H.C. Value is not fixed and does vary. Help would be greatly appreciated as this has really puzzled me. I have updated the firmware and went to older versions - same issue. I have searched for this topic on the likes of YouTube and other forums and cannot find some information. Fingers crossed one of you can help me with this.
Hello fellow astronomers, I have come to the forums as I have depleted all other options.
I own an NEQ5 GoTo with a Skywatcher 72ED. I have connected the mount to my computer using an EQDIRECT cable.
I am trying to use stellarium with ascom and eqmod to slew the mount to a desired object. I have configured my scope using the “telescope control” plugin in stellarium. In the past I had successfully achieved slewing through stellarium.
The problem is that now, one month later, when opening stellarium and trying to slew the telescope to a selected object (using either the “slew telescope to” panel or the shortcut (control + 1)) the mount moves for a fraction of a second and then stops, stellarium freezes and then the scope indicator in stellarium slides quickly to the horizon, and EQMOD control panel displays “horizon limit horizon limit” error. (Let’s call this the “main failure mode”.)
Note that :
I can use EQMOD and slew the scope manually without problem. If using it in tandem with stellarium, when I do so the scope indicator in stellarium moves without issue.
I have used the “resync encoders” button on EQMOD to establish the home position, but this does not affect the behavior.
I can use ascom device hub to slew the scope manually without a problem as well.
The main failure mode described above happens most of the time. However, I sometimes get other erratic behavior in stellarium:
Sometimes, when trying to slew the scope in stellarium, the mount moves for a second then stops (as described above), yet the scope indicator in stellarium moves to the selected object not the horizon, then the mount starts to track (even though it has not yet slewed).
Or, rarely, when trying to slew the scope in stellarium, the mount physically moves (seemingly to the object) and starts tracking, the scope indicator moves to the selected object -- appearing to work normally. But then, when trying to slew the scope a second time to a different object, it fails again as described in the main failure mode above.
I have tried opening stellarium as administrator but I still get one of the three outcomes when trying to slew.
Does anyone have any insight on this ?
I have a CPC 800 Edge HD as well as an Orion Starshoot Autoguider. I recently ordered a ZWO ASI294 MC Pro colour camera. In terms of the auto guide function I had planned on using PHD2 (which I already downloaded onto my Mac laptop). In terms of researching software that would allow for control of the camera I understand there are a number of options. I considered purchasing an ASIair, however, I understand that is not compatible with the Orion Starshoot Autoguider, and therefore I would need to replace that with a ZWO. I am hesitant to want to do that, even though it would be convenient not to have to bother with laptop connectivity. Right now I've been using my iPhone for goto functionality with Starsense and Skyportal wifi. I understand there are a number of options available for Windows based PCs in terms of control of camera and image acquisition. BackyardEOS (for DSLR cameras), Astrophotography Tool, and Nebulosity. These seem to be the most popular. However, it looks to me as though APT is just for Windows based PC. As well, not sure the extent to which Nebulosity is seamless when it comes to Mac compatibility. Is there a recommended Image Acquisition software for Mac users? Is a Windows PC laptop dedicated for astrophotography the best approach (e.g. second hand etc)? I would appreciate your recommendations. Thanks
