Having trouble with PI--HELP!!!

[rdryfoos]

I've watched the Warren Keller videos, and it seems that the screens always look very different.  When I try to apply an STF to teh Histogram Transformation function--it turns the image white--I follow the tutorial.  I open an unstretched image--apply an auto STF stretch then open the Histogram Transformation Function, paste the instance to the bottom bar of the HTF then paste the new instance of the HTF to the image and it turns the image white--the HTF has histograms both on top and the bottom.  This is not working as it is shown in the videos.

Another really big thing is the batch processing is not available--it is not in my processes and when I follow the tutorial and go to manage add ons, it is not in the list.  How can I post a Pic if I can't do batch preprocessing?

I find PI to be ridiculously difficult--Nothing works the same as the videos.  I tried the 45 free license and in that I was told that the Batch processing would be available when I got the license.

Hehehehe, don't panic, after applying STF to the Histogram window you need reset the STF window or press F12.
The Batch Preprocessing is located in Script/Batch Processing/Batch Preprocessing

Thanks--but I have tried resetting the STF prior to transfering the new instance of the HTF to the image.  No matter what I do, when I transfer the new instance of the HTF to the image (after transferring the STF to the HTF), the image gets blown out to the white end.

No need to panic.  Be very exact in following things in order:

1. Open Image
2. Open STF
3. Apply STF to image
4. Open HTF
5 Drag STF new instance icon to bottom bar of HTF
6. Reset STF (image should go dark)
7. Close STF
8. Drag HTF new instance icon to image
9. Image should now be stretched to the same parameters as the original STF

Enjoy

Thank you.  It worked.

1 more quick thing--I can't use channel combine on SII, Ha, OIII channels as RGB--(Hubble Pallet).  How do you channel combine narrowband frames?

Use the ChannelCombination process. Open your narrowband masters. You can then assign any filter to any one of R, G or B.

I tried that in Channel combination--but it said I had to use R,G,B images--would not accept Ha, SII, OIII.  So I tried it in LRGB combination without the L and it seemed to work--does that make sense?

[jkmorse]

Yes,

You are just substituting out Ha, OIII and SII for the RGB channels, though people often weight the contributions differently.

If you are interested, I have a PI workbook that I share with others that covers the tools in detail (though I don't use batch processing).  If interested, just drop me a note at jkmorse57@gmail.com and I will happily send along my latest version.

Best,

Hi Rodd, Thanks for your support! In PI Part-1, PI-3 Primer-3 we state "...open the HistogramTransformation tool, and select the appropriate view. Grab the New Instance arrow, and drag it directly to this bar. Disabling the STF, Apply or drag this New Instance to the image, and bam!  The screen stretch has been applied as a permanent one." We also clearly show that, highlighted by a green callout box. Everything was laid out extremely carefully in the IP4AP.com tutorials. Attention must be paid to the details. I'm hopeful that the other 'always' instances you mention are as easily explainable. Do bear in mind that Part-1 was recorded in v. 1.7 and will look somewhat cosmetically different, though functionality remains largely identical. Never hesitate to contact us privately Rodd if you have other issues, and thanks again!

Thanks Wahren--I managed to get the STF/HST issue solved.  I have another question--the Batch Processing Script will not allow me to run it unless I have ALL the following:-Darks, flats for all filters, and biases.  Often, I do not have flats for every filter but I still want to process the photos.  I could always stack in Nebulosity, but I am trying to avoid using any other software so I can post on the PI forum.  Any solutions?

Thanks,

Rodd

An option is not to use Batch Processing at all, I never have.  Use ImageCalibration, the script for CosmeticCorrection, StarAlignment and finally ImageIntegration.  It allows you to control things like using a single flat for each filter, and really does not take that much longer than the preprocess script.  I create a Temp folder to house the files, do each process / script in the order above, then delete the temps once you have your masters.

Thanks--is it automated?  If I have 30-40 subs of 3-4 different filters can I do a batch approach, or is it sub by sub?

[JoLo]

No, each of the processes / scripts will handle all of the subs for a given filter.  Calibration, Alignment and Integration have to be done on a filter by filter basis, but all of the subs for each filter can be loaded and run as a batch.  With CosmeticCorrection, you can load all your subs at once and run the script.

Great--thanks.  I'm coming along.
