We had a clear spell in Brisbane on the evening of Sat/Sun 21/22 Apr 2018, although the seeing was quite variable, estimated to be between 3-5/10 on the Pickering Scale.
I grabbed 39 sets of RGB data, 30 sec each filter with a pause of 210 secs between sets, spanning 11:50pm (21st) to 03:15am (22nd) with Jupiter transiting the Meridian at 01:07 am (AEST). From these RGB sets I managed to generate a 39 frame animation.
South is at the top of the animation.
Date(UT)=21042018.
Start(UT)=135005.153.
End(UT)=171542.914.
Tak Mewlon 210 F11.5.
TeleVue 2” PowerMate x2.0.
Camera=ZWO ASI290MM.
SX USB Filterwheel.
R=30 sec.
G=30 sec.
B=30 sec.
Pause=210 sec.
Diameter=44.21".
Magnitude=-2.47.
Focal Length=4830mm.
Resolution=0.12".
Altitude:
Start = 78 deg (E).
End = 57 deg (W).
Seeing:
Variable from 3 to 5 Pickering Scale.

I have attached a single frame from the sequence, where the seeing had dropped to around 4/10. It is interesting to see the larger image scale using the ASI290MM (2.9micron pixels) compared to my previous effort with the ASI120MM-S (3.75micron pixels).
