The other side

[Camelopardalis (Dunk)]

Folks,

What a difference a day makes! Not only was Jupiter putting a different face forward from the previous night, but the seeing seems to have improved too (or I did something wrong in processing!).

Same kit: Edge 11, TV Powermate 2.5x, ZWO ASI224MC

Cheers,
Dunk

Beautiful shot. Can you break down the processing for me. How many frames, Registax or Autostakkert, any post processing etc

[blinky (Leigh)]

hoooweee what a cracka! hope your pleased with that one! congratulations. got myself a c11 now so you've set the bar!

[Camelopardalis (Dunk)]

Thanks Chris, Leigh! It's all about the conditions, I was just lucky with two decent nights

Before I get going, I go for a mag 2 or so star to check collimation and this also gives an indication as to the conditions. Ideally we want a perfectly steady star but that must be very rare! Also verify you've got good focus. These two are key to getting a good capture. Well, that and the sky!

My basic processing workflow is:
- stack in AS!3. Small chunks, about 30seconds worth each
- WinJupos derotation with results from stacking (aim for a handful)
- sharpening in tool of choice (I tend to overdo it!)
- usually a splash of extra colour (I find the 224 a bit anemic)

This image was composed of 12 captures of 3000 frames (at 100fps) each, ~about 1000 frames from each stacked, then derotated before a little sharpening and a boost to the saturation.

Nice and sharp, very well done!

[oernulfs (Ørnulf)]

Definitely one of the best Jupiter images I've seen

[Spookyer (Brett)]

Duncan, great shot mate, one of the clearest I have seen, well done.

Brett

[Camelopardalis (Dunk)]

Thanks Bo, Ørnulf and Brett! I've noticed that it looks better scaled down to about 3/4 size, it loses the graininess a bit

[Paul Haese]

Nice image, maybe a little over sharpened but still nice data. I think it would be good to up the resample and make it bigger. This is clearly nice data and it deserves a bigger look.

[Camelopardalis (Dunk)]

Thanks Paul, indeed I try to find the balance between detail and noise, but often overshoot!

Will give it a shot with the drizzle and see how it comes out...thanks for the tip.

[Retrograde (Pete)]

Stunning image Dunk!

[Camelopardalis (Dunk)]

Thanks Pete!

[Camelopardalis (Dunk)]

Here's a drizzled version from the same data set...

Maybe it's my dodgy processing, or maybe I had coincidentally hit the limits of the seeing, or maybe my scope has nothing more to give

[andyc (Andy)]

Really great Dunk, that's a beauty. And thanks for the tips/info on processing - I need to crack the whole Winjupos thing

[Camelopardalis (Dunk)]

Thanks Andy! I certainly can't claim to have mastered WJ, but getting to grips with it...maybe

[astronobob (Bob)]

Certainly an awesome Jupiter you have there Dunk, , Well done
Im finding this side is pretty much the only side there is and apparently there a big storm on the Dark-side-of-the-moon aswell I live to see them both one night
Great Imaging & processing - It also looks good @ 125 -150 %
Rgrds ...

[Camelopardalis (Dunk)]

Thanks Bob!

Yeah that side is still pretty interesting, but on a good night I want swirls and spots and...and...who knows?

I'd actually captured some data the night prior to this, with the GRS in shot, so when I get the time I'll go back and trawl through that again.

[LostInSp_ce]

Spectacular image!

[Camelopardalis (Dunk)]

Cheers!

Far out Dunk, looks incredible mate. Amazing detail!
