Looks good to me!  Have you got some RGB to add it to as well?  I've got a (large!) set of data for this one, just waiting to be processed and you are driving my enthusiasm.

 

 

Being extra fussy, maybe the stars are a little elongated, in what looks like the RA axis/direction.  Are you guiding now?

They are aren't they.

Strange, I was getting ~1.14" RMS which is less than  the pixel scale of my camera. Time to check my subs...

Hmm... they all show that amount of trailing!

I did lose guiding a few times that evening, it looks like those are either 5-minute unguided subs or something was moving - but if it was it was very consistent.

How about this? I've used an assymetric blur kernel and deconvolution, then

extra de-noising.

That seems to have done the trick.  It looks a little 'crispier' too
