The strong winds finally abated last night around 8pm leaving a reasonably clear stable moonless evening.
I haven’t imaged the Tarantula with my 10” Newt yet so grabbed a quick one in Ha at low altitudes ( 22 degrees to 33 degrees ) Pretty tired last night so shut down just after midnight.
Guiding was surprisingly good around 0.50 to 0.55 total rms at such low altitudes
