Yes I am very happy with the results. The scope was still up to 2.5 degrees above ambient, didn't have time to use cooler at all, so goodness knows what could have been. Although its hard for me to emagine.
My thanks must go to Asi, for his hours of showing me the finer points on processing, his eye for detail and subtle changes is far beyond my ability.
Wow Lester, they are just brilliant! I never would have believed there would actually be a problem with capturing 'too much colour' with a scope on Jupiter. I reckon it's possibly camera related though. Perhaps lowering the saturation at capture time would help ?
Could you tell my the settings you captured with please? Spare no details.
Theres a wealth of detail just waiting to be tweaked out of those AVI's yet
You really do need Astraimage mate! I don't understand why the free version has been taken off the internet! Can anyone help here? Gotta get Lester a copy of this...It's driving me CRAZY!
The last posted image recipe= 5fps 70% gain 0 gamma 1/10 second exposure 55% saturation 25% brightness
Most of my others were very similar to this except the last where I tried 30% gain 25% gamma 1/5 second exposure 100% saturation 25% brightness and trashed it= full of Onions.
Ah...So thats why the dark limb...25% brightness! I keep reading NOT to touch brightness & contrast EVER! I have experimented with brightness I must admit (lowered it to 40%) But now I leave it alone.
Thanks for trying those lower wavelets Lester. No, looks like you had it right with your original wavelets, for these anyway - if you do crack an 8+ seeing night give it another go then. Hard to believe you were still 2.5deg from ambient - incredible.
And like the guys say you gotta get Astra Image - you just gotta.
Don't want to give you a big head or anything, but your second post is close to matching the very best Jupiter image from an amateur based scope I've ever seen. I second Dennis, I think it would benefit greatly by toning back the color. Its scary to think what extensive image processing would bring in such an image! The whorls and other activity in the polar areas is fantastic!
God I wish for such seeing (and elevation, Jupiter will get no higher than about 42 deg from my location). I don't want to wait till 2010, so I guess a trip is called for.
Congrats on an image you can treasure for a long time.
Lester, these images are just fantastic! So much to see in the belts and amazing fine detail even in the festoons.
There's been so much new info for me in this thread about capture and processing settings, some of it very different from what I've been using, especially the low brightness setting. And the zero gamma, isn't that supposed to lead to onion rings? I've never had any success using wavelets 1, 2 or 3 - always seems to increase the grain objectionably.
Going through the processing blahs at the moment. Just too many variables involved and it's hard to pin down cause and effect when you change settings. I can see a (long) period of experimentation coming up.
3 months ago I didn't know a thing about imaging Jupiter.
This forum has been fantastic for its guidance in many areas of amateur astronomy. I couldn't have done it so quick without the help of many kind fellow astronomers here. Plus the conditions last night were good, but not an 8/10.
thanks for the link to Astro-image; (you will laugh) I copied it into program files, couldn't find it, so restarted computer and still cannot find it. I will wait for Celestine to come home after football to retreive it for me.
Thanks Dave,
