Heya,

 

Happy mother's day to all, hope you have a wonderful weekend or memory of your loved ones!

 

I was able to get a little sky time this morning, a quick 20ish minute session. Seeing was fairly good this morning with a much smaller temperature delta as my summer weather is rolling in after a weird cold snap in early May here in Florida. AR2822 presented in photosphere and the upper & lower chromosphere at the same image scales.

Nice collection of images !!     How do you  do your artificial coloring?  I have done this taking the gray image into photoshop and then using hue/saturation. But your colors seem to come out especially nicely. Do you just use a "colored" grayscale, or do you do something fancier??

Thanks all, hope everyone is having a good weekend. Pretty awesome that this AR popped off an M class flare that knocked out some radio bands in North America on the 7th! I need to build a solar radio telescope or HAM radio to record these things one day.

Hi,

 

I use a levels adjustment layer. I image in mono. My final image is taken into CS5.1 and I make it a RGB image (still B&W but now it has color channels). Then a simple levels adjustment layer will false color the entire image. You can adjust the R, G & B channels individually (the mid-point in each channel) in the levels adjustment. I saved a few values that I re-use as presets so I can instantly color by just applying the preset I made for both my yellow/orange and my purple so that it's consistent. I cover my general work flow in my tutorial here and at the end I show how I color with levels with my pre-sets. My yellow/orange is made with a levels adjustment where you set the mid-point in the levels to the following: red channel 1.6, green channel 0.8, & blue channel 0.2. You can of course adjust it and go deeper or go for other colors but this is what I use. For my UV, I do the same method but my values are: red channel 1.5, green channel 0.8, & blue channel 1.8. I do everything in layers so that I can quickly output any step within the workflow as a final image if I want. If you're interested, watch my 18~20 minute video tutorial on workflow linked above it should cover nearly every step rapidly.

 

Very best,

Very best,

This is an excellent video and a must watch. This tutorial is the foundation to my own work and still up to today, i go back to re-watch the video step-by-step. Thanks Marty for doing this video!!
