Hi Rob,

I am using an IDAS LPS-P2 filter in my set-up. Would that distort the colours? If I change the RGBR sequencing, do you know what I should change it to?

Thanks for your help

When I open my Canon 7D Raw images and then user the ScreenTransferFunction's nuclear button. The image is displayed as sky blue. I don't think this is quite right. I think there is a setting for how the bayer colour matrix is interpreted, but I may be wrong. I think there is an option to configure the RGBR sequencing when the file is processed. Can someone put my out of my misery.

Many thanks

Hi Guys,

I don't see them in any images until the final integration. At least if they are there, they are too subtle for me to see. They do seem to be worse were I combine images from separate imaging sessions i.e. where the orientation of the camera is very different between the sessions.

V strange.

Does anyone know what causes this when I process my images?



This is my workflow:

1. convert CR2 to Fits
2. Create master dark
3. Image calibration
4. Debayer
5. Star alignment
6 image integration

The image is the result of step 6 without doing anything else in PI and is a 2:1 crop before STF or any stretching takes place

Thanks Lex,

I do do the update in the 'normal' way, but it still disappeared. If you or someone can tell me how to restore the script on  OS X then I would be very grateful.

Thanks again

Oops! Absolutely right have posted this in the bugs section.

Sorry for the confusion

Bug Reports / BatchPreprocessing script disappeared
« on: 2012 April 30 23:29:28 »
Reposting this post since I posted into the wrong group

I installed the new BatchPreprocessing script (OS X) and there it was. Selected the menu option and launched the script all was fine. Didn't actually do anything with the script  (was going to have a proper play this evening) went to launch the script this evening and it has disappeared. Somehow I did managed to crash PI -may be that's why it's gone. Anyone know how to get the script back?

Many thanks

Thank you for your super quick response!!

Running StartAlignment the process windows states that it has found 50867 stars, but then the alignment process errors out saying 0 star(s) found - need at least six stars.

Clearly there are enough stars, so what could be causing this error?

Thanks for your help

Hi Stargazer,

see http://pixinsight.com/forum/index.php?topic=2570.0 for a complete DSLR calibration workflow. Note that the use of DSS is certainly much easier than the use of PI for calibration and integration, and it only makes sense to proceed to PI to tweak the last bits of signal out of your inage sets. Calibration with flats, biases, darks definitely is a prerequisite for this.

Georg

Hi Georg,

There are many references to that topic in this and other forums. It is very informative especially to a newbie like myself, but I am not sure it is complete, or at least there are steps that are ambiguous. Also many of the switches or options are not explained. Following the steps as best I can, with trial and error, I am not able to get the result I hope for. Generally the result is not as good as DSS not withstanding the doughnuts.

My frustration is I am convinced that PI can produce the post possible result, I just haven't found 'the way' despite many hours of trial and error.

I'm shooting with a Hutech Light Pollution Filter LPS-48.

Here are the same subs processed into a single images and then opened in PI.

The top images was processed entirely in PI. Note the green is after de-bayering. Running background neutralisation does indeed remove the green cast but it just shifts the colour problem elsewhere.
...

Could you make your PI fits image availlable somewhere? You probably use BackgroundCalibration and ColorCalibration in a wrong fashion.
Georg

Hi, PI image hasn't had DBE or background neutralisation applied, although if I do apply them colour and contrast are lost at least in comparison to DSS.

Hey Nocturnal,

Oouch!!

That's harsh!

I just took the defaults ..for a quick and dirty comparison.

So what are the cosmetic option(s) I should click off?

Thanks for your help
