I was hoping that the tightly spaced Jupiter/Mars pair would clear the trees before the dawn sky brightened too much – the trees blocking my Eastern Horizon had grown considerably in the last 12 months. 
Tantalising glimpses of Jupiter and the 4 Galilean Moons materialised on the LCD on the back of the camera as the topmost branches swayed in the light breeze when finally, Jupiter and Mars cleared the top of the trees and I could get to work recording this close conjunction.
I took several frames at varying ISO speeds (ISO100 to ISO3200) and shutter speeds (1/8 sec to 30 secs) so I could later select frames that showed the field stars (Jupiter and Mars grossly over exposed) and the disc of Jupiter with the equatorial bands.
A little bit of Photoshop magic allowed me to combine the sets and produce this composite.
Cheers

PS - According to ST3 Pro, the separation between Jupiter and Mars was some 14 arc mins, less than ½ diameter of the full Moon. Brisbane, Qld, Australia, 7th Jan 2018 at 4:15 am AEST (UT+10).
