Importance of the image restoration in the solar imaging.

Rusted,
Your words cracked me up. I'm still chuckling

When I find a moment I will add my favorite tutorial links. But as you noted, they were hard won. There is a sub forum here which has tutorials listedbbut is is pretty thin.

Mark, Alexandra, The Great Attractor (creator of imPPG) and others all have excellent tutorials and there are many others on various forums.

Like I said, I will post what I have soon.

Cheers,
Jack

I could never get it to do anything useful until today. Not just by fiddling with the controls.
How, on earth, are beginners supposed to know what to do?
Taken in combination, the number of possibilities for the settings must be almost infinite!

Is there a "family" of settings which provide a useful base for making more rapid progress?
That might be far more useful to the majority of forum members.
Rather than vague generalisations about producing these specific "masterpieces."

We happily share details of our successful mods and equipment choices.
Why not show the same generosity in successful, initial, settings for processing software?
There may be countless solar masterpieces hiding undiscovered on member's hard drives.
We just need to know how to drag them screaming and kicking into reality.

But did you read the processing tutorial that goes with IMPPG?
Solar imaging is the same as every form of astrophotography. The processing part is equally important as the actual gathering of raw images, some say it is more important. There is no absolute strategy, but with the pointers Alexandra gave in her tutorial and for example the IMPPG tutorial, you already have the basic tools, start using them. But it will take a lot of time and energy to develop your own style and strategies. There is no absolute solution.
Try a radically different approach than seems normal. Try to understand exactly what each processing step really does with your image, don't just learn a trick.
Try in IMPPG for LR low sigma with really high iterations, dare to go really high. Do with unsharp masking the same (so low sigma) with a real high amount. etc.

I downloaded imppg ages ago.
I have no recollection of any "training wheels."

Thank you for the reminder.
With all due apologies to Alexandra.

Nice job, Gov. Glad to see IMPPG in your toolkit.

Valery...

I have a question about a line in your original post on this topic, and I need help to clarify what you mean by "with the right approach to restoring images destroyed by the atmosphere".

By "restoration", do you mean in the selection/alignment/stacking process in order to produce the best raw file to process, or are you "restoring" images through the entire process form start to finish?

I only ask as I find the term and how to interpret it to be open to interpretation depending on how one reads it and looks at the topic.

Thanks for any clarification you can provide,
Brian

Brian,

Sorry, english is not my native language and may be I can't express exactly what do I mean. I wrote this headline as close as possible within my ability to express mysef in english.

No worries Valery, I just wanted to clarify if the restoration referred to the image alignment/stacking or the entire image processing sequence.

It referres to a full process. All stages and components are important.

I take it that you have no plans to share details of your processing techniques with the solar community then?

Your second post is as contributing to the solar community as your first one. Welcome to the forum!
There is no such thing as a feee lunch, can you post a picture you made, maybe then we can give you some advise.

There you go. Only have this old WL image on this iPad no Ha images. Not looking for any tips in particular, just thought a thread basically saying “post processing is important” would go on to actually provide some details.

Freddie, that is a lovely image!

Oh my g** Freddie are you going to give us some lessons?

Thank you very much Pedro.
Absolutely amazing resources!

I don't have Photoshop. So I use PhotoFiltre7.
Perhaps I should look at Gimp.
