Yes, it’s a pity - they are out-of-focus.
One thing I can see here, the second lot you took at ISO800 without any signs of noise.

Nice to see some globulars! I'm sure you'll nail the focus next time Jorge

Thank you, IanP and Rolf.
As soon the sky permits I will try again.
With ISO 800 I needed work with noise filter. And the result was good.
