Potentially good shots here but they are out of focus. Ha filters can be a little hard to focus. I generally focus in luminance filter and use that. My luminance filter and Ha filter are parfocal though or close enough for jazz.

Focus, focus, and did I mention, focus?

I really should get a luminance filter, the bahtinov mask does not work in Halpha with this setup.
