Reasonable seeing on the 30th though dew once again making my secondary lose its impact. As such higher gain is needed. These are straight RGBs which look more natural than the versions with red lums. That's what I like the most about these processes the natural Feel. See if you agree. Thanks

Excellent detail and I like the colouring, but do you know why there is a peripheral darkening? Vignetting?

Hi Dave its a combination of the shadow effect as Jupiter approaches earth. And likely some clipping during processing.
Cheers

That's the best Jupiter I've seen so far this season, what equipment & processing details were used if you don't mind me asking?

I haven't managed to image it yet this season.

Forget part of my last question as I just found your other post; http://www.skyatnightmagazine.com/forum/3-more-from-oct-30th-t127658.html

But I'd still be interested in what processes were used to get those images,

Hi Tich I did 3 runs of 3 mins each RGB Astronomik type 2 filters At 60 fps 1/60 secs exposure. Then aligned using Winjupos. to counteract the long duration of the captures. Frame count stack for each Channel was roughly about 10.000 frames possibly slightly less. Sometimes I did blue at 1/130th secs exposure. so the frame count stack would have been about 5000 frames. I think I did some at 30 and some at 60 fps on blue. Just experimenting. Stacked on AS/2 drizzle 1.5 then downsized. dyadic wavelets on registax 5 mostly wavelet two. possibly some with wavelet one one in combination with wavelet two. Further processing, Noise reduction, sharpening, colour, and levels adjustments on Image analyser. Would take a age to go into finer detail. But I will say I did increase local contrast. on analyzer, adjusting maximum contrast. and extra contrast. And increasing colour saturation. I check the colour balance on reg 5 auto colour balance. then adjust by eye back on analyser usually a green and blue lift. Slightly more blue, as it is always the weakest signal.
