So this is cool... :) If you look in both images, directly left of 1745 at the edge of the solar disc is a darker mottled area of "disturbance". Reddit user plaidhat1 and I discussed it yesterday when I posted this over there. Welllllllll....today we appear to have our answer. THREE X-class flares c...

For grins and giggles, I went back and restacked, this time with a 2x drizzle. Then I cropped out the area of the major activity, and then went pretty heavy with the saturation, and used the HDR Optimize preset and the Contrast module to try to really grab as much definition as I could out of the su...

Could you roughly outline what steps you used to get to this results? Just Sharpen, Color, and Rotate/Mirror as mentioned above. :) Sharpen was default all around, Color was bumping saturation to about 125%, max on both high and low end, and then I ran Red and Green up to about 3.0 for some yellow,...

I was setting up early for a shot at M101 tonight, and decided to grab some video of the Sun. There's been a lot of sunspot activity being imaged of late, and even though i don't have any dedicated solar equipment, thought I'd see what I could capture. Fairly sure that what we have here is sunspots ...

Ya know...there's ALWAYS a relevant XKCD...amusing this one is so recent.

I don't know how many kinds of awesome there are, Ivo...

But you are all of them.

admin wrote:Well, joking aside, you can actually use the Color module to create a false color version of your b & w image. It's useful for Solar images for example.

Quit it, Ivo. I'm tryin' to be a smart-ass over here...

admin wrote:Ok, I had a look at the individual frames as well. They definitely contain color data. It appears something went wrong during the stacking stage resulting in a black & white image!

So...what we're after here is a version of the color module that works with Luminance data only

Hrmmm....

Well, now, I'm getting some pretty strange results here.

When I get to the color module, I can run all three sliders to their absolute max...and get NO change. Nothing. Not so much as a pixel's difference. It's as though there's no color data there.

I'm afraid these are quite essential. It's this or bothering the user with saturation response curves... :( Fair enough...I'll just nod my head and pretend to understand that. http://i35.photobucket.com/albums/d177/ChibiKiriyama/NoddingSmiley.gif Yep, good observation and exactly what I was thinkin...
