Hey all,

 

I made an acquisition and processing tutorial a while back (3 years ago? Yikes!) and it is fairly dated in terms of what I'm doing these days. I've been asked for a long time to make a new one showing what I'm doing these days. Specifically how I'm processing a single shot image for both the surface and prominences and how to process them together to show prominences and the surface at once. I've abandoned doing split images and composites and strictly work from one image using layers. Acquisition does not use gamma at all anymore. Nothing terribly fancy, but it's not exactly intuitive so hopefully this new video will illustrate most of the fundamentals to get you started. Instead of an hour, this time it's only 18 minutes. It's real time from start to finish. I'm sorry for the long "waiting periods" where I'm just waiting for the software to finish its routine, it lasts 1.5 minutes and 30 seconds tops typically at first. The first 4 minutes is literally just stacking & alignment in AS!3. I typically will go faster than this, but wanted to slow down enough to try to talk through what I'm doing as I do it. Hopefully you can see each action on the screen. I may have made a few mistakes or said a few incorrect things or terms, forgive me for that, this is not my day job. I really hope it helps folk get more into processing as its not difficult or intimidating when you see a simple process with only a few things that are used. The key is good data to begin with and a good exposure value. Today's data came from a 100mm F10 achromatic refractor and an ASI290MM camera with an HA filter. I used FireCapture to acquire the data with a defocused flat frame. No gamma is used. I target anywhere from 65% to 72% histogram fill. That's it! The processing is fast and simple. I have a few presets that I use, but they are all defaults in Photoshop. A lot of the numbers I use for parameters are based on image scale, so keep that in mind, experiment with your own values. The only preset I use that is not a default is my coloring scheme. I color with levels in Photoshop, and my values are Red: 1.6, Green 0.8, Blue 0.2 (these are mid-point values).

I will add soon an acquisition video to show how I capture the data to allow single-shot processing easier. I use FireCapture for the flat. So I'll go through focus, exposure and histogram, gamma on/off, flat frame use, acquisition, to produce the above TIFs that can be processed rapidly this way for limb & surface from a single shot.

I haven't been using ImPPG for processing solar images. I had it, but hadn't started playing around with it until a few days ago. The second day the Tone Curve editor disappeared and I've tried everything to get it back. Apparently, I'm not the first person to have this problem either.  Marty ... or anyone reading this ... I wonder if you'd have a look at the posts here and tell me if you have any ideas. https://www.cloudyni...pg-version-060/

Hrm, the little window with the histogram? You may have dragged it off screen? It defaults back to wherever you left it, so if its off screen it will stay off there. I'm not at my PC right now to test it, but I would see if you can disable the floating window and re-enable it to toggle it to default back with the primary window in the software?

So clicking on the curves icon (fourth icon from the left in the menu bar) doesn't bring back the Tone Curve?

Apparently it's an issue with specific Windows (v 10?) and it not handling window position appropriately. The source software author advised to delete or rename the .ini file in its hidden App directory under the user folder in AppData under Windows and it worked for the other people that were having this specific issue.

Same here, I have Win 7 on all my machines still. I refused to update until things don't work anymore. Most of the software was written under a different operating system, so it's a gamble trying to run it on something newer. Things move around in the windows environment as it is....

Very best,

I'd like to try that, but the problem is, I can't find that file. One would think if all the ImPPG files are deleted and the newest version downloaded that everything would be ok. But it's not. Like any computer program there are pieces of it in places that just doing a simple delete of files does not get. It's too bad the program is not in the uninstall list. I'm figuring there's a piece in the registry somewhere. But that's something I'm not going to fool around with. 

I've  contacted the Great Attractor, but he hasn't responded.

No worries, everything works in Win10. The latest release of IMPPG has a very minor bug as mentioned here, it's an awesome piece of software, free, and it now uses GPU acceleration. Well worth any small hiccups!

I was just having a more detailed look at your tutorial, Marty. I was wondeing about the section that runs from about 5:28 to 6:28. Was the purpose of that section for you to just inspect the image for the detail it contained? Just before you say "Now what I'm going to do with this is I'm going to back off ... " I thought you might have been going to hit the Select And Process The Whole Image button. But you didn't. So I guess that was an inspection step? 

 

I just took one of my videos and went through the steps of the tutorial, by the way.  It's a great job you've done here again!

Yes! I don't need to see much other than surface spicules to know I'm in the ballpark. If I can see spicules, it's got enough contrast and sharp enough. This helps me figure my arbitrary values to keep them noticeable, but without over-sharpening. I do that at a high contrast with levels, but then expand levels again at the end to not lose faint prom detail on the limb. I used it to inspect general quality and basically how much blur to work with.

Hi Tom,

 

It's a Sirius EQ-G / HEQ5 class mount, pier mounted with a steel pier extension. I have 29lbs of counter weights. It handles my C8 & 80mm Frac and my 150mm Frac and all the imaging gear and filters for solar system imaging nicely, at its capacity limits.

This one covers focus, flat calibration, exposure.
