I can definitely see the Iris in there!

Did you do the imaging in moonlight?

Wow!  Got that one in the cross hairs!  I thought that might be an intervening star but Googled other images and found some with the same result, although not as clearly defined as yours.  Like it!

Best

Looks interesting.  A bit of a blue cast plus I can't understand why your refractor is giving diffraction spikes.
