Hi Jeff. I suspect what you are seeing on his mount is cable drag and or balance. If the stars are diagonal its usually polar alignment but his seems to be going left to right sometimes indicating drag or balance. But he does not have a heavy load so my guess cables on the mount.

I know I am going to be in a tiny minority here, but if your polar alignment was that tight and you have a well balanced level mount I am surprised at the oval stars at 10 minutes. Have you done PEC training on that mount? If not, then you could be seeing periodic error in the worm. On Sat, Jan 13, 2018 at 4:37 PM Astrophotography <

Last night I tweaked my polar alignment using SharpCap's polar alignment routine. Attached is a screenshot of the reported result and a 10 minute unguided single frame that was dark corrected, opened in Nebulosity and binned with the 2x Adaptive setting and saved as a jpg.
I am quite pleased with the improvement. The stars are fairly round, but not perfect. I need to work on getting my guide scope re-mounted and configured.
The background is quite bright as it was taken after 6am this morning.
