I have a SkyWatcher AZ-EQ5 mount. It’s all working fine, except I have an issue with alignment. This applies whether I’m in EQ or Alt-Az mode.

I set it up using  one or two star align without problems.
However if I use the handset to GoTo another object, I usually need to do fine tuning adjustments to centre on the new object. But the mount disregards these adjustments, so if I use the GoTo system to centre on a nearby object, or revisit the original object a second time, it’s still off by the same amount.
How do I tell the mount that I have centred on the new object and that it should now be aligned with that object ? 
My iOptron MiniTower has a feature that does exactly this – once set up correctly and aligned, for each new object I go to there is an “ALIGN” option, and if I use this it now knows the correct position. Can I do this with SkyWatcher and Synscan ?

Thanks. Angelo

Press escape then press and hold escape it will flash up centre object do that finish with right and up ( helps with backlash) then press enter your next object should be a lot closer.

It's called PAE (periodic error alignment) it is in the handset user manual it does help, I have used it on a couple of objects at the beginning of my night and then everything is in the FOV your very welcome.

I had a similar issue with my EQ6r mount last week. Really frustrating! After a few people on here giving me some tips and a friend of mine spending a few hours on the phone I tried a few things. So I did a factory reset to clear all stored data to ensure nothing was pushing the mount out. I then updated the hand controller software and updated the mount gears software on skywatcher website. Then I went back to basics with the polar alignment so I did the test of putting polaris in centre of reticle (cross in centre) rotated 180 degrees checking polaris stayed smack central and didn't drift off. Once I knew that the axis were aligned correctly I went to the next test. For the second test I placed polaris into the circles using the middle circle track. Unlocked my RA clutch and rotated to see if polaris stayed on that circle and rotated like a train round a track without drifting. Once I knew that was accurate I rechecked the polar allignment position for my polar app unlocked clutches got everything facing back north. Turned the mount off and back on then I entered all the details as shown on synscanit and went for 2 star allignment. Everything was perfect for me last night. Good luck hope you sort it. 👍

      Skywatcher illuminated reticule eyepiece. It has a red crosshair pattern. I think it’s 24mm rather than the newer 12.5mm models. Great condition. Looking for £35 including postage from France. Thanks.

      Hi All,
      I am currently researching which setup to purchase as my first proper scope (once they are back in stock).
      I thought I had settled on the Skywatcher Explorer 130ps AZ GTi but then I saw the Skywatcher Star Discovery 150i for just a little more money.
      Could anyone please tell me the difference between the 2 OTA's (other than the different aperture size), and also the difference between the 2 mounts?
      I realise that the AZ GTi can be modified to run in EQ mode whereas the Star Discovery can't.
      Can the Star Discovery view all the way to the zenith or does the OTA catch the mount or tripod before it gets there?
       
      Thanks

      I've been trying to image a couple of galaxies per night, one pre and one post flip.  On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data. 
      Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
      Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
      Mount: Mesu e200
      Guiding: ZWO OAGv2, 290MM, PHD2
      Filters: None
      Software: APT for capture, APP and PS for processing
       
      I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before.  I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time.  I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
       
      CC welcome.

      Help! I have a Skywatcher EQM-35 PRO GoTo mount for which I am unable to get the star alignment right, whether I use 1 star, 2 star, or 3 star alignment. I can get it polar aligned without any problem, but when it comes to star alignment it is way out. Choosing Sirius as the first star to align, the scope slews to the right general direction but about 20 deg. lower and slightly to the east of where it should be. The mount is perfectly level. I have checked, and double checked, all the settings, longitude and latitude ( N 50:41:46 W 3:13:53), Date in mm:dd:yr format, Time, Time Zone (0), Elevation (25m) and Daylight Saving Time (Yes). I am at a complete loss what to do next. I am getting close to chucking the lot into the sea!!! Before I do that anyone got any suggestions?

      As above looking for scopes for both these mounts. Thanks
