JUPITER & Io, Red, Green, Blue process - 10March

Hi All, this is about the best of the lot of avis's (not much in it though, no "standouts") from yesterday morning showing the Io shadow transit. I split the avi in Avi Raw into red, green and blue and processed separately in Registax 3 ran the separate colour channels through LR deconvolution in Astra Image and combined.

I've included the separate colours here too - interesting the difference in detail that each colour channel reveals. Still a little trouble with the colours in recombining. I also include at upper right an image from the same avi processed in colour and unsharp masked - prefer the colour on that though perhaps a bit more fine detail on the combined.

Anyway, enjoy

Looks great, a fine shot. It's just too blue after recombine, that's all. When you recombine and it comes out like then when you preview (by pressing "Update"), change the blue weight to 1.1 and press update again, see if that fixes it.

yup what ice says,

do you do a histo stretchin registax stacking section???

Yes i reckon the detail is more in the colours.

did you have a big difference in the number of different colours that made the grade ie 450 red, 300 blue etc

lovely detail.

can you do me a favour and chuck in a 5x powermate and give it a rip

Doh... why didn't I think of that.I use the colour weights all the time when I'm just doing a deconvolution recombine, but do something different and ol'd grey goes on holidays Thanks Mike.

Hey DP, I can put a 4x powermate in, but the seeing just hasn't been up to the task. Even that time a few weeks back it wasn't quite as good as the 2.5x, though that was on the 7in mewlon and was lacking a little light. First chance I get I'll give 'er another go on Jupiter but with the c9.25.

reprocess on combined

I reprocessed the combined this time reducing the blue colour weight and repasted into the composite image. Fair improvement I reckon thanks guys.

That's better... the separate processing seems to make a noticeable difference, for me it seems a bit sharper then the colour processed vesion.

the reason i ask is that i want to put what i think is damien peaches best shot on a page and then ices, dennis, robs, bird and mine.

and i want all of our biggest scale if possible. the quality does not really matter to start with. If i have the biggest scale of each of us then i can reduce all the rest down to the same size and then start to compare where each of us is at against damien. we have tree reflectors and three sct's.

I really want to start getting a feel for what is it in a peach image makes them look so good detail or colour etc etc

sure, I'm happy to give it a whirl... I've got the dreaded lurgy though so might not be for a few nights... no way I'm dragging my carcass from bed tomorrow morning
