This is my ISO1600 data from 2016 (31 60s subs) plus new ISO800 data (32 120s subs) from last night.

      Complete beginner question regarding using this mount.
      When I have tried to set up and align the mount , the goto targeting is off by many degrees.  Here's what I do - can someone tell me what I'm doing wrong!?
       
      With the power off:
      Align the tripod and mount to North and, with the clutches released, set the declination to my latitude (52deg 28' N). and the mount in the weights-down home position.
      Lock the clutches and fine tune the alignment on Polaris using the mechanical adjustments on the mount.
       
      Turn the power on:
      Set up the date, time and location, elevation etc. in the handset (noting the American Date format and Longitude first (set to W 1deg 48')
      DST = Yes
      Select 1 Star align
      Pick a star, I usually try Procyon or Betelguese depending on the time.
      The scope slews to vaguely the right direction but actually nowhere near.  It can take 2 or 3 minutes of manual slewing to centre the star in the eyepiece.  Finishing, of course, with an up and right movement.
      Finally, press Enter to complete the alignment ==> Alignment Successful says the handset optimistically.  
      Now from the object menu pick another target.  Try, say, Polaris which was where I started and ... nowhere near it.   It's the same regardless of the selected target.
       
      I have tried 2 star alignment and 3 star alignment, a factory reset before starting,  but nothing seems to work.   Once i'm lined up on a target the mount tracks nicely - it just won't go where I want it to!
      Not yet at my wits end but - Help!

      Hi everyone.
      A friend has an EQ3 Goto mount, I think it's the Sky-watcher one.    Currently, I know nothing about them, except that he's having issues getting it to work.  To the point that he's getting so frustrated with it he's seriously starting to thinking about throwing the mount away.
      He's described what's happening to me.    What he's saying is that the mount never points to the place where he's asked it to point.    He's saying that say the scope is supposed to point towards something in Orion, it'll end up pointing somewhere on the other side of the sky.     He's also said that it doesn't seem to want to track past a certain point in RA.
      I'd thought rather than simply jump in and try to help him out and get just as confused,  I was wondering if there's some check list of common EQ3 faults that I could work through to see if we can solve the issue.
       
      Once thing I do know is that he's running the mount from a dedicated tracer battery, so it maybe safe to assume that the power supply is good.   (althought it's something I'm going to double check as I don't want to miss anything)

      34 2-minute subs, no darks. Exif says 6c so the sensor was probably somewhere between -15 and -20C!
      Begging for a few more hours!

      To my surprise last night wasn't a complete write-off. I managed to get another 135 minutes of decent 5-minute frames of M31, this time without my LP filter. Total of 3 hours 55 minutes with my cooled canon. There was some streaky noise caused by drifting very thin cloud.
      The subs were much brighter and no moon plus high elevation meant I got away with it. The mix of frames with and without filter stopped the core being too badly blown out. I think I've controlled my urge to over-process this time, but any suggestions for improvement welcome.
