Yes, it's quite good, but the stars seem stretched vertically, or is it just me?

Thank you! Yes, that can happen with stars. The stars in the hydrogen channel are slightly larger than those in the oxygen channel across almost the entire field, and they protrude especially from the top—likely due to poorer guiding in one of the hydrogen sessions.

In terms of detail, the California Nebula is a rather unremarkable object.
But in this color treatment, it looks very effective and dramatic.
