Hi all.
Here's my best Jupiter yet, taken yesterday morning between 4:30am and 6am.
I took 16 avi's in total, and i've processed all of them. They're all of similar quality, so i'll be making an animated gif as soon as I get some time. Here's the 3 best out of the bunch, avi's 1, 8 and 16, which is convenient, as it shows the start, middle and end of my session.
The top image shows Io to the left and Ganymede to the right, both resolved as discs and perhaps a hint of detail (at least, colouration) on Ganymede! There's swirling detail inside the GRS, and in the bottom right image, you can see detail inside Mini-Red, similar to Bird's capture the other day.
The seeing was 8/10, fluctuating a little but pretty consistent. I battled passing low cloud for the whole session, which meant I had to throw away an additional 4 or 5 avi's, and some of the 16 I kept had changing brightness thanks to thin cloud passing over.
The avi's were captured @ 5fps, gain and gamma were at 50%, shutter was 1/25. The brightness level was between 200-225 for the whole session (except for when the cloud passed over). Happy to report, no onion rings :)
Usual processing routine, split into R/G/B, ppmcentre, Registax (200 frames of each channel stacked), AstraImage LR deconvolution and final curves adjustment and USM in photoshop.
Comments welcome. I'll post the animation tomorrow, if I get time to work on it.
