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

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 h...

Nice work, Phil. To make sure, asking for workflow is for a commonly available file such as what Alfred provided. Then the numbers and workflow are relevant. I would love for Valerie to post his raw sunspot file then his obviously lovely processing Regarding the Alfred file, I love the softer-then-m...

Val, Your sunspot image is indeed amazing, but I think we'd love to see your workflow to get it. Recognizing that every optical train merits slightly different treatment, I'd love to see how you went from the Raw Image to Stacking to LR Decon (if you do) to PS/GIMP. Just a comment about using the un...

This is an outstanding thread. I am carefully looking at each attempt and learning. Great job to Marty and Pedro and of course Val and Alfred. I will try again taking some of the new techniques.

Alfred you good person you! Ok...I got your file and put it into IMPPG. I had to use VERY high SIGMAs (maybe that's part of the secret) and these settings: 2019-10-17_21-17-21.jpg Then I brought it into GIMP for some more processing and ended up with this: 94920 1500f Alfred to Val to imppg to gimp....

That’s what I suspected. Dang. If he wants to post it I will host it.

So I just downloaded Alfred's large image (I hope that was OK) and ran it through IMPPG. I was not able to get any kind of usable image anywhere near suitable for the next stage of processing...say in GIMP. I tried every combination of settings including some bizarre extremes. Maybe I should not hav...

I agree with Alexandra, the ‘usual’ is pretty standard. My only difference is I choose, ‘CROPPED’ and ‘IMPROVED TRACKING”. I’ve done lots of variations and I frankly don’t see much difference in AP SIZE or even 10/20/50/75 percent of images.

Game on! I am going to try and process this myself and describe my steps. That was the purpose of my Training File folder I created a whole back. Trying to replicate the works of Rembrandt teach us many valuable lessons.

Nice contrast in my humble opinion...eleven the one with modest processing.

Ummm , I still think Val is cheating by using a space suit and a go pro unit a few miles above the surface. It’s the only plausible explanation for any of his high res work.

Seriously good stuff.

Terrific motion clarity

Love that long prom as well.

Brian,
Thanks for posting all the compares. Every data point like these are helpful.

And nice shots as well.

Thanks all. What's interesting is that the more I Practice the more I can see comments like Val's. But Alexandra's point is spot on, risk of a poor Quark in exchange vs the angst of exchange versus just pure enjoyment.

Cheers,
Jack

Crab nuggets. Ok! Good catch.

Thanks Mark

Good stuff, Stu. Thank you. The large blobs are from the flats. I will indeed work on the small little round artifacts as directed.

Jack

Lol. No offense taken!!

Lol. No offense taken!!

What is your Quark dial set at? Idike to s3e more contrast on the surface portions and that is where my questions are driving.

Also, which capture software are you using and are you using any kind of secondary filter like a polarizer or a UVIR Cut?

Cheers,
Jack

I like them all. What is your processing workflow? Do you use IMPPG? That is key for me to really adjust some curves, contrast and LR Deconvolution.

That is a great combo.

That is an amazing and heavy lift. Well done sir.
