Jupiter & moons

Jupiter & moons
Today I flickered past another photo community I once visited often, and realised I hadn't posted this image here. In 2013, with Jupiter high and bright, I wanted a photo of Jupiter with its moons. It was easier said than done! Although I could get Jupiter, in long telephoto the long exposures needed for the moons resulted in significant motion blur. The only alternative was a very high ISO (12800 @ 1/50) which left Jupiter just a bright white circle. So I did the "HDR thing" and substituted a correctly exposed Jupiter image. Best viewed on black.

It worked well George. The amount of noise looks almost like an asteroid field but I would have never guessed that this could be Jupiter but then I can see the giant cloud ring. You need a tracker like Steve has, perhaps? All the same your effort has paid off and produced a great astro photo. Well done.

Many thanks, Herb. Unfortunately I don't think a tracker would help much here, because the movement of the moons is also around Jupiter and therefore not the same as starfields in relation to us.

I think tracking will help a bit. Most of the blurring occurs because of the unsteady earth atmosphere. Have a look in my album on planets

that's the only way to get it right. Use two exposures. A fine view of Jupiter and its moons

And there was I , thinking that such tricks only happened in landscape photography Ko. As you say though, to show this to our restricted human eyes, we have to give a little help and in this case (like in some country landscapes) the ends certainly justify the means. ~ Herb

I've tried for this shot but my tele isn't tele enough and there is an ISO deficiency. Congratulations on making a great image.

Some day maybe I'll try for something like this but for now, I'll just be staggered by your talent! :)

This is great! That's exactly what I did to get both Jupiter and it's moons exposed properly. But, I used a regular daytime ISO and about a 1/30 of a second.

Thank you for your kind comment. Yes, the Jupiter part of my image was taken on something like those settings, it was the moons part that needed the extra ISO for them to show up.
