Skies cleared overnight and was treated to reasonable though quite variable seeing at 3am. The disk of jupiter was fairly stable, but the seeing fuzzed out half the time. There were some moments of 8/10 seeing. But short lived.
Anyway, decided just to run with the 4x powermate and the sps900nc cam. 90 sec exposures at 10fps and 1/10th sec exposure. Gain 50%, Gamma 50% and Brightness 50% Reasonable detail on most avi's but generally a lot of grain and some onioning after processing.
The shots here are from the same avi, both separate process of R, G and B colour channels and recombined with LR deconvolution in Astra Image 2.0 and varying degrees of gamma and curves post processing in pixel studio 2.0.
well my friend, I am extremely relieved. They amount of light is great compared to the neximage.
Gauntlets out gentlemen, we have a c9.25 draining all available power in port lincoln and an extension tube. There is now a very usable 4x powermate on a c9.25 and a tasmanian with a large extension tube.
Lets go chasing Bird and Mike!!!
Large scale Jupiters, here we come me hearties!
On a serious note,
I have emailed the main guy that writes the macros and posted to the yahoo forums re raw conversions for 900nc. Fingers crossed. You might be the first in the world to use it!!!
I gave 3 iterations of ME at 1.3 a go on each colour channel. Results below show this on the left and another go with LR deconvolution (4 iterations at 1.5) on the right.
For me it looks like LR is still the way to go, but no doubt this varies from one setup to another.
Terrific work Rob...really nice natural look - the one at very top left has a sort of Pioneer Jupiter feel about it. Well..that was my first reaction anyhow. Very cool mate.

Thanks Steve, these are obviously far from the best, but I'm still marveling (having returned to Astronomy last year aster a 10 year hiatus) at how such shots are even possible from ground based amateur scopes. I remember Pioneer and Voyager vividly but never thought anything like the same cloud detail might be achieved with a lousy SCT (which back then, to me, seemed to be good at nothing).
Wow - those are incredible images of Jupiter at that image scale, using the x4 Powermate. If the seeing conditions when you captured these avi’s were as poor as last night/this morning, then your results are nothing short of miraculous.
I was out until 5:00am this morning after a long absence from the ‘scope, and only managed to grab a single avi as the seeing was quite atrocious. I could not even get Jupiter to focus as it was bouncing around so much.
excellent work Robert , always like the colour balance you get ....damn if i can replicate it
