Processing Examples
« on: 2013 February 24 17:29:23 »
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.

Thank you!!!   :) :) :)
I think this way is easy an quick for pointing examples for those that are starting to use PI. I will update the link with each new example.
Saludos. Alejandro.

Great thread :)
Have you considered making some videotutorials, like Harry?

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.

Thank you all, :)
Yes, it is more organized now, I will add links while examples are coming.

Videos...  :-\, maybe, but the problem is that I am not good in english..., maybe in spanish ::)..., luckly we have Harry's, Gerald's, etc. :smiley: :smiley: :smiley:

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!
Clear Skies!!

Hi all,
Most of the processing examples present here are now also available in Spanish :) in PixInsight Resources
See this post for more information about the page.
