Great to see an image from this high end setup. Congrats! Getting both scopes to see the same object at the same time must have been very hard.

Looks good except the blue halos on the bright stars. I wonder what caused that - needed a refocus on the blue subs? The Trius can bloat a bit on bright stars with some setups. Perhaps extra decon on blue and ensure focus is redone on blue.

Also TEC180 achieves thermal equilibrium in my experience after about 1 hour so a refocus after the first hour is essential then it tends to be stable all night.

Greg.
