Eggy stars are eggy stars at any focal length. It just means you tend to "get away with" worse tracking at shorter focal length. 770mm is starting to get into medium focal length and eggy stars will show up in your images.
I am not saying EQ6 gives eggy stars - I know a lot use them and their are many fine images. But I bet they had to tweak their mounts to achieve that.
Whereas with the AP mount once setup it will give round stars routinely and you can concentrate on other aspects of imaging. Without a good mount you tend to spend more time trying to get round stars and sometimes you win and sometimes you don't.
Do you notice it in an image? Yes. Eggy stars also means the object of interest is also blurred/smeared. So you lose sharpness, detail. A well tracked image with a nice scope should have a certain crispness to it.
Microcontrast, fine detail and overly pleasing sharp and crisp look to the image is impossible without good tracking.
Additionally it would be much much harder if you wanted to do longer exposures like say 20 to 30 minutes for less noisy narrowband images like Ha, O111 and S11.
In short until you can achieve round stars routinely in your setup you haven't even reached the bus stop yet let alone got on the bus!
An AP 1100 would be a dream mount and I believe AP preload PEC into their mounts as well right? That's a big plus too. It also has a powerful capacity so if later on you want to image with a larger scope (noone here ever upgrades their gear to larger, bigger and better do they??) then your mount is ready to go without that having to be the upgrade first.
