Excellent Geof
I love Centaurus A.....processed a few versions of it myself actually
Some nice details in there for sure.
You have got a bright yellow core huh?..looks dramatic.
That C9.25 looks to be a good scope and you have nailed down the guiding to take full advantage of the optics it would seem?
I had a bit of a surf around your pbase site, love the observatory.
