It is ok if you rguiding is less than that

Usually it is but there are times where it is more depends on what target I shoot

What targets do you wanna shoot when you call 0.77 "/pixel undersampled?

That was part of my question, if 0.77 is a bad value since I did not know
I just assumed it because I read it in a guide for pixel scale

Here you go. Punch in the data of your setup or future setup.
Well I don't know the guide you read. So it could be true in the very context of the guide.
The worst factor for us is Seeing. You can't change seeing. And it changes constantly. Sometimes good - sometimes bad. And seeing is the biggest limiting factor for your scope.
You can't beat it.
That being said. It's always the sensor+scope combo that gives u the scale.
tinier pixels for a shorter FL are nice - and bigger pixels at bigger scales. Somewhere in between being over and undersampled is a sweet spot. Although being oversampled is not as bad as being undersampled. And being undersampled - you can always drizzle and it will look better.
In your case - 533 with with 0.77"/ pixel - you are very OK. But you will need stable guiding less than that value
