Further to my 'weird goings on' Post a few months back, ZWO were unable or unwilling to find a solution to fix their problem with the ASIAIR Plus giving me weird guiding graphs on my Ioptron CEM70EC2 mount. Instead they blamed it on my not so perfect round stars (which are seriously good enough) and said it must be my mount etc...
Polar alignment is really good and the RA and DEC axes are well adjusted and I can take 2 to 3 min unguided pics most nights dependent on the seeing etc..
So take a look at my uploaded log from last night. In sessions 1 & 2 you can see the dec running nicely and the RA increasing in value with an rms error of 7.77 and 11.54. Yet my pics taken during these times are really good with very nice round stars.. Session 4 shows both axes guiding nicely for 1 and 3/4 hrs with rms=0.58. So its looking normal here.
Session 6 and 7 of the logs are also nice running at 0.7 rms..
I have tried to upload a pic taken at 11.05pm during the rising RA axis graph with rms=11.54 but an error on this forum wont let me. It is a 5 min guided pic and the stars look pretty good and round for an rms = 11.54. Something weird with ASIAIR and Ioptron mounts is going on. ZWO wont address it. Others with Ioptron mounts have had similar issues and no solutions from ZWO.
What is going on???
