Schickard, Wargentin, and Phocyldes

Wonderful stuff Mike! Very happy to have been of some assistance grin

The weird ghosting you mention is a consequence of Registax alignment routine I think. I sometimes get it on two sides of the image and that's when you're forced to crop. I can' see the seaming though: it may just be that you know where it is and tend to be over-critical.

Ciao Mike

My apologies to Registax and Lumenera users!

Posted By Gianluca Valentini
Thanks for understanding I wasn't wasting your precious time wink

However, Cor emailed and asked for a 12bit file captured by a Lumenera. I sent a couple to him (one from the B&W Infinity and one from the LU075C) and he told me that they worked perfectly in Registax. I haven't tested it yet, but Anthony tells me in his post that he's been doing it for a while now and that almost everything works. So I will try it tonight and report to you my findings.

Alas, I just found yet another bug in Streampix 3.20, i.e. that it doesn't export the 36bit color files and it crashes in the middle of the job (approx 1000 frames). This happens only for 640x480 frames, while the files captured with the ROI function are ok up to 2500 frames.

Ciao everybody

Just an experiment!

Thank you all guys for the great help and the tricks that you taught me.

The result is a team effort, so congratulations to all!

Fantastic Image Chris!!

Amazing colours and detail. Even processing is smoother than usual. BRAVISSIMO grin

More Saturn Storm

Posted By Gianluca Valentini
Very nice Jim! I love the hint of the C ring in front of the planet's orb. I wouldn't know how to do it, but I'm sure you can make it show all around and it would a great sight smile There must be a trade off between globe's detail and C ring: hope you find it so your images would be just perfect!!

Ciao Jim

You sure can get the colours right now wink

Which one?

Posted By Gianluca Valentini
While this one has been applied only a very strong UM in Photoshop.


I can't decide which one is better, so I'd like some opinions from you guys. I find that sometimes UM, even if heavily applied, brings out almost the same detail, but not the same noise. Although wavelets are selective filters, I feel that the trade off detail/noise isn't worthy.

Graet job Jim grin

You captured and processed the delicate banding of the planet extremely well. Which camera did you use? Atik or Lumenera?

Hello Robert and welcome to the world of imaging.

It can all seem very frustrating in the beginning and I can assure you it stays that way wink but for different reasons as you go along.

I believe there is a very good tutorial on the registax website at http://registax.astronomy.net/ , or at least there is an explanation of what the commands mean, but I believe that, after reading that, is mostly "learn as you go", as you correctly put it.
I myself am not a great registax user (I mostly use Iris, because that's what I started with some time ago), but I'm sure that you'll find good advice and lots of help here for your future, inevitable, problems.

So hang in there and don't give up: you'll be a great imager like some of the guys posting here in no time grin

Ciao

Question for Paolo and/or others HELP!

Posted By Gianluca Valentini
I would try what Paul suggests: check if the Hardware Settings in the Correction Matrices you have Daylight as active option and instead set it to NONE (also the demosaic option should be on NONE)

I have posted a similar image (same camera, same subject) a few days ago and I don't have that problem. Here it is again.

If you use Streampix, I suggest you also check Lucam Recorder by Heyko Wilkens (the software I used to capture the attached image): easy to use (much faster although not so complete) and now works great with Registax because it captures 12bit TIFF files and those can now be dragged directly into Registax and processed without 2 gigabyte limit . You can process uo to 10,000 12bit TIFF frames grin . Best part of all this is that it is FREE grin grin .
To know more, join the Lumenera group at Yahoo here http://groups.yahoo.com/group/lumenerausers.

Question for Paolo and/or others HELP!

Posted By Gianluca Valentini
Hello Tyler,

I believe that you have a tentative technical explanation in my post: you should try changing the correction matrix setting and see if that is the problem (as I think it is).
On the other hand, if you check my image, it may not be great, but it is not affected by the same pattern that yours displays and that logically rules out a systematic problem with the camera model. It may still be due to the camera, but then it would be your specimen that might needs repairing.

To rule out software issues, the image I attach here was captured using Streampix. Again it isn't a good image, but it doesn't have any strange pattern. If you contact me privately, I can send you a settings file and you can try to use that with your camera to see if the problem persists, in which case you should, as Paolo suggested, contact your vendor or Lumenera directly.

I hope this is helpful Tyler.

Ciao
Luca
