I am pretty happy with the guiding,ecstatic with the mount, but I did notice the elongation, probably because the stars were false-bloated thanks to the focus error. I have compared the stars to a circular tool in PS, and they are certainly not perfectly round. I'd like to somehow "fix" that, being a pedant.
I could call the data I got "The Squished Bug Nebula"... the focus error makes it look like a blurry red smudge
