Love the colours Alex Fredo would be proud of ya!
While it does look very vibrant and on the surface at least, to be a similar comparison, err?.. you have simply shrunk the Hubble shot down to match your field

What you need to do if you wish to demonstrate the resolution capability of your system is zoom in on a small bit of your frame and compare "that" to the same bit by Hubble. Most images look high res when displayed in wider field but small size.
Sorry if I sound like a wowser and I am not trying to deminish your display as it does look very nice, bit like a gelatto like icecream even?
