Hi All,

After a more than 12 month hiatus in my planetary imaging I was lured from bed early Sunday morning to give Jove a go... to say I was unprepared is an understatement.

My slick routine of old has dissolved into blank staring at bits of plumbing, filters, power cables (of which there were too many for my available sockets) and dohickkeys, wondering what goes where. I honestly couldn't remember where in the sequence of mirro flip diagonal, filter wheel, camera and barlow to actually place the barlow ... IC capture just seemed like a bewildering array of numbers with no purpose. I struggled on.

Seeing has something apparently to do with how wobbly things look on the screen. Well the best I can say is it it looked a bit wobbly with little detail apparent and focussing a nightmare of guess work (thank god for a shadow transit!). What this amounted to out of 10 I'm not so sure, maybe a 4-5/10

Anyway, the upside is everything appeared at least to work. I'm sure there must have been some developments though in firmware for the DMK and post-processing that I could do well to get across.

I managed to get through the processing hurdles and pulled a couple of images together below about 30 minutes apart. Not exactly impressive, but perhaps the first tentative step in getting back on top of this stuff as the Jupiter season unfurls.

cheers guys,

Rob

That's a very fine image and a great welcome back to planetary imaging, Rob! I've certainly missed having you around and seeing your work.

Great to have you back.

I really like the colours and processing on this one, nicely done.

Hey Rob!

Welcome back. Great to see you imaging again.

30fps...at 1/60th of a second exp? How did you manage to fill the histogram?

I can't go that many fps at that exp with my 9.25....without Joops being very dark.

Again...welcome back:thumbsup:

If I could get half as good as that i would be stoked, (Not that I do and Planetary Work) :whistle: top stuff indeed.

Leon :thumbsup:

Hi Rob

Well, well, well; aren’t you just the comeback kid! A very impressive result for the 1st light in 12 months – I’d be very happy to pull those wonderful images out of the poor seeing soup!

Nice to see you back on the boards.

Cheers

Dennis

Thanks for the words of encouragment guys and good to be back.

Hi Mike - i hear you're using the USB version of the DMK... how does it compare for performance?

Hi Matt - with 30fps and 1/60th of a second (DMK) I have to wind up the gain seriously high... over 900 (out of 1023) on each colour channel except green.

and Hi Ron, I'd love to join you guys at Cambroon sometime... just need to build up now from spending 2 hours a year on astronomy to something a little more healthy:P

cheers,

Rob

Hey Rob. Unless I've missed it, you didn't mention whether you used a barlow or not?
