Congratulations to Paolo!

Posted By Gianluca Valentini

I might be the last one to know (being in Italy we receive S&T very late compared to you U.S.) but I wanted to congratulate Paolo on yet another image published on the Feb. issue of S&T.

Well done diavolo d'un Lazzarotti grin

Interesting for Lumenera and Registax users!

Posted By Gianluca Valentini

Hello everyone,

for all you guys using lumenera cameras out there, I found out there is an easy way to take advantage of the 12bit mode capturing option even for Registax users. In fact I thought and said until today that capturing a 12bit .seq file to translate in avi was a waste of disk space, since avis are limited to 8bit and all the tonal richness of the 12bit would get lost in the translation.
I had a exchange of email with Cor Berrevoets to report a problem I encountered with Streampix avis (again the new 3.20 release needs Virtualdub re-processing) and he told me that one could use the translation into PNG files to exploit the full 12bit of the seq files. I've tried it and it works great! So now you can export a seq file into a bunch of separate PNG files and then drag them into Registax (very important: DO NOT SELECT THE FILES FROM THE SELECT MENU, BUT JUST DRAG THEM INTO THE GREEN INITIAL SCREEN AND REGISTAX WILL DO THE REST!). Using this method you can even circumvent the "2 Gb limit" problem since you can process up to 10,000 frames this way.

Just thought it could be useful to someone out there.

Ciao all

My 1st Saturn in a long time!!

Posted By Gianluca Valentini

Hello guys,

this is my first Saturn in a while! It isn't great and the color is off, but I had a hard time with Streampix and the cold so I did the best I could considering the situation. I had to re-install the software twice cwy since it gave some problem with the ROI function, but eventually I made it smile

So here it is:
UTC 22:30
Lumenera LU075C
C11 @f30
200/2500 stacked and processed in Registax and PS and resampledat 125%

Ciao

Since I can't get the right colour.....

Posted By Gianluca Valentini

..... I decided to post a B&W Saturn sad

It was taken in less than fair seeing (the rule lately around here)
Feb 7th 2006 UTC 22:26
C11 at F30 (Baader FFC)
Lumenera Infinity 2-1 at 18fps
200/1500 in Iris and PS

Ciao

Just an experiment!

Posted By Gianluca Valentini

Hello guys,

since here the weather keeps pn teasing us with exceptional transparency, but dreadful seeing, last night I collected some images only to create a mosaic of the whole moon. I had to use the 4" Tak at F8 since 800mm was the longest focal that I was able to use to beat the worst seeing I've ever seen on a clear night :C

For this reason the mosaic isn't very interesting, but it was obtained with four shots and I believe I'm beginning to get the gist of this "mosaic-ing" with PS.
Size reduced to 80%. Camera is Lumenera Infinity 2-1; each section is a stack of 10 frames out of 50.

Ciao all

My apologies to Registax and Lumenera users!

Posted By Gianluca Valentini

Hello guys,

I must apologize for reporting a wrong info :S : PNG files are not 12bit, but just 8bit files. Mike Wirth just told me that Cor spoke to Damian Peach that clarified the misunderstanding. I'm sorry: I was just reporting what I learned from Cor: my intentions were good smile
So, Registax users, we are back to 8 bit processing. Hopefully Cor will soon give us a +8bit alternative (tiff, fits, whatever). In the meanwhile, try Iris guys!

Ciao

Eventually a decent Saturn!

Posted By Gianluca Valentini

Hello guys,

after battling with the seeing and with the white balance in Streampix, I managed to get a decent image of Saturn (mostly thanks to Paolo who helped me with the color settings). I have a group of files to process, so I hope to get some more decent ones (hopefully even a better one grin )

DATA:

Feb 13th '06 UTC 21:57
C11 at F32 (approx)
LU075C at 24fps 500/2500 frames stacked and wavelets in Iris
Levels and a bit of UM in PS. size is 150% of the original.

Thanks and ciao

Which one?

Posted By Gianluca Valentini

I processed these 2 images differently:

The one attached here has been processed using wavelets and UM and has been upsized to 125%.

My 1st LRGB!! Thanks Tyler

Posted By Gianluca Valentini

Hello everyone,

I tried my first LRGB with 2 images taken with LU075 and Infinity 2-1M. It isn't much, but I'm still experimenting. It's very coarse, probably because both the stacked images were already processed and the color one maybe a bit too much, but the outcome is still satisfying to me grin The iamges were also taken approx 40 minutes apart and that doesn't make it a wise attempt.

Taken with C11 at F30. By me grin
Tyler taught me how to do this in Photoshop, so to him goes a special thank you!

Question for the more experienced Photoshoppers

Posted By Gianluca Valentini

Hello everyone,

I would like an info on creating LRGB images: when I use the color image as layer should I choose the option COLOR in the drop down menu of the layer pallette? I had this doubt because Tyler told me that, in the case I was pasting the luminance layer onto the color, I should have chosen the LUMINOSITY option, but since I do the opposite and I paste the color onto the luminance....

However, the result doesn't seem to be as good as when I leave the option to normal, so I'm a little confused and I need "a little help from my friends" grin

Ciao to all

Luca
