It was a bit of a race against the brightening dawn skies, hoping that Jupiter and Mars would clear the tree-line before they were dimmed by the impending day light.

I glimpsed tantalising views of Jupiter and the 4 Galilean Moons through the thin foliage as the topmost branches swayed in the light breeze then finally, Jupiter and Mars heaved themselves clear of the tree-line and I got 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.

Whilst waiting, I also grabbed some shots of Messier 42 (M42) a bright nebula with its show piece Trapezium stars dazzling like diamonds in the middle of the frame.

Canon 5D Mk IV, 210mm dia F/11.5 telescope with a x1.6 Extender to give an efl of 3860mm.

Cheers

Dennis

Excellent. Hard to comprehend that Galileo built his own telescope to see those moons 400 years ago.

Lovely as usual, Dennis. Been a while since I've seen you post - but I haven't been around much or doing much astro myself lately.

Hi Troy

Great to hear from you and trust you are well.:-)

Time, weather and other commitments have kept me away from any serious astronomy for a while, but hopefully with Jupiter being well placed for us folks down under, I’ll be back!:-)

Cheers

Dennis
