I'm trying to figure out if I need to take shorter exposures to stop the core from being blown out? When I stretch it, I start seeing the fainter outer arms but then the core just explodes...

 

Or does my data is just not good enough?

You are stretching in some sort of non-astro app, right? GIMP, Photoshop maybe?

 

AutoSTF in PixInsight (one click) hints at what's possible -- you need to work on your stretching technique (and focus :-)).
