Hi all,
While I was checking over the old BAS 10" on Friday night, getting it ready for Mt Coot-tha Public Field Night Saturday, I had a go at capturing Jupiter with my iPhone. I used the video as there doesn't seem to be any way to adjust the photograph exposure. I have one app that allows longer exposure but it just multiplies all signals and bins. So basically useless.
But in the first video I took, as Jupiter went out of view, there is one frame that was perfect! This has turned out better than photos I took back when film was in and it was so much easier and instant! You can even see all the moons (I have just grabbed the frame and only increased the contrast around Ganymede to make it easier to see). If Jupiter wasn't so close to the edge you would see Callisto way off to the right.
Astrophotography has come such a long way to make it so accessible to beginners and the public!
I found (by accident) to photograph Jupiter with iPhone if you expand the planets image to maximum (two fingers on screen) and then touch the center of overexposed Jupiter the exposure automatically adjusts from overexposed to correct. Hope this helps.
I think I might have tried that at the time but we hadn't made up a holder then, so it was a bit tricky to hold it still and in the correct spot. The scope doesn't track and the eyepiece had terrible eye relief.
Tony found holding your finger on the object for more than 2 seconds will lock the auto focus. He found it good to focus and lock it on the moon then move back to Jupiter.
As soon as the clouds clear I'm going to try it again!
That focus lock works on my HTC
I didn't know that thanks
Good job with the I-thing and Jupiter , sometimes its amazing what you can do with simple things without spending $$$$$$
Now the slippery slope of AP
