That's a really beautiful Carina Nebula there Paul, lovely colours and nice crisp detail throughout. The
Mystic Mountain has come out clearly, which is not often seen.
And the IC2944 image is stunning, spectacular work Paul.
I've just this week filled the last two positions in my filter wheel so I now have a complete set of Astrodon 3nm narrowband filters - looking forward to trying them out!
BTW I totally agree re Focusmax, it is really worth getting this up and running.
And about guiding, your experience is similar to mine; I get best results using 0.6s - only sometime switching to 1s exposures if seeing interferes.
