Processing Examples

I open this thread to group processing examples I posted in the different sub forums.
The title corresponds to the original in the subforum. It is detailed who owns the image and date of processing, because as time passes my techniques have changed and may be useful to know when it was published.
Comments, criticisms and suggestions for improvement are welcome in order to improve our knowledge and use of PixInsight.

Thanks Alejandro!
Its a great idea to bring all your valuable impressive processing examples under one TOC.
Its like a book now. It saves a lot of searching time for the different "HowTo"s and makes all visible at a glance!

Thanks, Great Work!

Alejandro, this is a terrific idea.  Losing access to any of these wonderful tutorials would truly be a loss to the PI community.  Thanks you for making it so easy to find these great resources.

Hi Alejandro
Thanks a lot for the list of your processing examples (with the main notes!!). I saved most of them; but there were still some missing.
Interesting to see also some examples on how to process solar images. Till now, I couldn'd find a lot on solar or planetary processings.

Earlier today, while reading your SMC NGC 292 thread, I was thinking "Huh, someone ought to put together a post with links to all of Alejandro's great tutorial threads, because that would be a fantastic resource."  Needless to say, at the time, I had not finished going through all the "Unread posts since last visit".  :D  Thank you for reading my mind.

This will, indeed, be a fantastic resource for us paduans still learning PI!  Keep up the good work.

I think this thread should definitely be made sticky, these are invaluable. Thank you for all the effort, Alejandro!

Hi,

First a big thank you to Alejandro for this huge tutorials!
Second, this is absolutely wort to make it sticky! Nearly all the processing steps needed for all cases is decribed here in!

Best!

Perhaps not the correct thread to put this under, but can someone point me to an example of handling a single RAW (M42 in this case) process flow?  I've got through the intro to 1.8 video, have a good handle on a number of things, but still struggle with even at times whether to use PURE_RAW for the import or use the standard import for DSLR_RAW (I struggle with color rendition with the PURE_RAW).  Also, I'd like to understand multiple masking.. again using M42 entire region, there are three distinct areas that can be processed individually..

Thanks in advance for any guidance.  I have Warren Keller's book..
