Jupiter - my best so far

Posted By Gianluca Valentini
Very nice image Russell!

Beautiful and detailed. It looks very bright on my screen, but I use an LCD and they are a breed apart as regards color calibration: it never looks right sad

Thanks for sharing Russell.

What's a good program for editing RAW?

Posted By Gianluca Valentini
Hello Don,

my advice is to try Iris: it i not as user friendly as Registax, but it is more complete as it manages DSO images as well as planetary. You can even capture avis or guide using a webcam within it! Furthermore, it has a specific area for RAW images (including Fuji's RAW). So, IMHO, it is the most complete freeware out there for astronomical image processing. Mind you, it can be discouraging at first, but it is an incredibly powerful tool.

You can find the English version (the program is originally in French) here: http://www.astrosurf.org/buil/us/iris/iris.htm . There you will find all the in depth explanations you may need.

Hope this helps.

Ciao

Jupiter through a 16"

Posted By Gianluca Valentini
Hi Jan,
it sounds like a difficult catch smile but the result is good.

Would you mind giving me a little more data, such as the scope focal length, no. of images captured and stacked, and all you can give me. High F ratio Newtonians should be good performers on planets, but that is mostly what I heard and I have no direct experience.

Thanks Jan for posting this image.

PS Please read my last reply in my last thread.

Hey Ed,

Leroi's shots are truly amazing 8O .

He was posting regularly here for a while, but then he stopped. I sure hope he comes back soon to grace our eyes with his beautiful work.

If you are reading this Leroi: we miss you and your work man sad

Ciao Ed

Hello Alan,
your shots are excellent as usual smile

So don't be shy and keep on sending this kind of stuff: that's one of the reasons why we are here grin

Ciao Alan

PS Paolo informs me that some great seeing is coming our way this week end: hope I can take advantage of it!

Jupiter Apr. 28th

Posted By Gianluca Valentini
Hello again,

this is the first attempt at approx. f/30 (difficult to judge with the modular Zeiss barlow). The seeing did not cooperate this time and I believe this is the best avi from that night at that focal length. I still have another one, but it doesn't look any better than this one, from a first look.

However, I was experimenting and I can't recall the UTC for this image.
Data are the same as the previous picture with the exception of the focal ratio (f/30) and the no. of frames acquired and stacked (1000/1800).

It seems that processing brought out some artifacts, so I have a difficult time assessing what is detail and what is processing problems. I believe that there's more artifacts than actual detail.

However, I would appreciate comments and advice on this one.

Ciao
Luca

I promise this is the last one for today wink

I have corrected the UTC on a previous post of mine and I post now the real 22:21 UTC image. I kind of like this one better than the previous one from this lot as processing came out much smoother, thanks (again) to Paolo's precious hints.

Thnaks and ciao to all.
