ZWO Improve ASIAIR accuracy of plate-solving to targets

Hi, I’m Ian and I live in Surrey in the UK.
You may have seen a couple of my previous videos (“Orion and Horsehead Nebulas Wide-screen Mosaic - Part 1: Planning and Accuracy” and “Important to know with the ASIAIR Pro”) where I highlighted some inaccuracies when the ZWO ASIAIR Pro plate-solves to targets.
I know a number of other KZfaqrs have also highlighted these issues such as Cuiv, The Lazy Geek.
Well, I’m please to say I think ZWO have improved this part of their software in their latest 1.8 Firmware release.
I’ve tested it with my Evostar 72ED (focal length 363mm) and my recent Esprit 120ED (focal length 863mm). I don’t think the increased focal length has caused this improvement I think it is what ZWO have described in their Firmware update as “Optimized accuracy of the Centre-Goto”.
It really seems to have worked as I’m now only off target by a few seconds on either the RA or DEC, which is much better than I was seeing before. This will really help when setting up an exact field of view or when doing mosaics in the plan mode.
Apologies in the video for the initial images of me, seems my phone was struggling to get a good focus in poor light.

Thank you for this video - excellent work. I agree, I own the ASI Pro & Plus - centering up of objects is very close to Telescopius ( which I use for planning ).

Hi Ian, thanks for this video! I was scratching my head the other night wondering why my asi air plus wasn't framing as pictured on the device. Im gonna give the coordinates method a try to avoid future disappointment. 👍

My mount cannot be controlled in the dec and goto sets it to 00:00:00. So it cannot center and I will turn auto centering off on the mount. Can you tell me what happens when the mount is rotated to the ra but cannot be centered? Does it proceed with the plans imaging or does it just end or loop for ever trying to center. I would like it to continue with the imaging and not concerned with accuracy.
