Hello Brian,

there is something I can't quite pinpoint with your image processing: the image looks a little "plastic-like". It looks like the underlying data could be good, so maybe it is just a matter of finding the right processing for them.
Can you give us a llittle more data on how the image was processed?

Hello Alan,

changes are very nicely documented this way! I love the Jan 21st image: it must have been a great night as the image seems to be the smoothest of the lot. All 3 are phenomenal, however!

Ciao Alan

Alright Tyler!

Great shot! You are perfectly welcome for the Lucam tip: I believe this little software will become better and better. Did you capture avi or tiff?

We're looking forward for you "doing some damage" with the Infinity man

Ciao Tyler

.... a mistery rising

The 2 pictures have been processed exactly the same way! There is no more sharpening or more processing of any kind to the 2 resulting LRGB images:

The only difference is that in version A I have set the RGB layer as NORMAL in the drop down of the layer's pallette, whereas in version B I chose the option COLOR for the RGB layer. The B&W layer was always used as LUMINOSITY (which I guess is equivalent to LUMINANCE) and was applied on top of the RGB picture which was then resized being smaller than the B&W.

So, the mistery is now why the difference is so evident and why the effect is so strikingly different between the "ring area" and the "orb area"? I agree with Alan and I think it would be great to have the ring area from picture A and the orb from picture B: Can that be accomplished in Photoshop? And, if yes, how?

Ciao guys and thanks for letting me have your valuable opinions.

PS special question for Alan: don't you think that the mistery could be that in fact the pictures retain their processing when merged with the RGB layer as NORMAL, while they don't when merged simply as COLOR? In other, and perhaps clearer, words, couldn't it be that picture A has the processing of both layers somehow summed, while picture B retained only the processing of the luminance layer? As a matter of fact, the RGB picture was especially well defined in the rings area and that could explain why the outcome LRGB was much better in that section when merged with that layer as normal.

Very smooth Tyler! I really love this one.

Isn't the low noise on the Infinity the greatest thing in a while?

What a phenomenal image John! Thanks for sharing it with us.

I must come to the next WSP since I've seen some great images coming from that event. I've also read that the seeing was amazing this year

Hope to be there and meet you in 2007 then!

Hello Tyler,

you sure are getting the hang of it This image is really VERY good.

The Infinity are really almost noise free, isn't it? How many frames did you use for this image? I don't know if you have already tried it, but it is enough to stack 50 12bit images to get a smooth and almost noise free image.
The times when you had doubts about this camera seem to be long gone

Ciao Tyler.

PS I finished moving my observatory in my new house in the country, and last night I had just enough cloud free sky to complete the drift align, so soon I'll be back in businees: BEWARE for my new images

very nice image Edward!
The LRGB technique yields great results, isn't it? Even more so if the luminance is taken with a quality camera like the DMK.

Hello Chris,

I agree with Paolo and John that, besides some processing issues (too bright and too grainy) this is one of the best Jupiter images in a while. I believe that with seeing conditions such as the one you enjoy there in the Philippines, you should not push processing so much and that would save a lot of faint detail that gets washed out.
Do you resample all your images? Because they seem awfully big for your imaging set up. If that is the case would you mind posting this image without resampling it?
Thanks for sharing with us your work: it helps forgetting seeing conditions around here :C

Phenomenal John 8O

Never seen so many shades of colour on the planet: simply fantastic.

the 2 images you've posted from the WSP are no doubt the best I've ever seen.

Ciao

Luca
