Colorising solar images

Last week I decided to use the ZWO ASI178MMC camera to do solar imaging with my Baader Herschel Prism wedge as I had not used a mono imager with this before. I found that the image captured even at the faster exposure 1/16,000 with zero gain, was overexposed to the point I actually required to use the ND3.0 filter to image with it.But as the sunspots were very small and the sun was not particularly interesting, I thought I would work on trying to colorise the images I had.

Now the images were processed and stacked with AutoStakkert!2 (the latest alpha version 2.6.1.4) and had wavelets applied with Registax 6. I adjusted the whitebalance to get a slightly yellow colour to the image first. Then the colorising was done with the histogram colour levels tool in Capture One Pro 8 (increasing the level of mid tones in red, while reducing this in blue and green). And now I have images much closer to those I see online, without needing to use Photoshop.

Anyway, here are the results below.

I am quite pleased with the results above, and all without needing to use layers. Anyway, I also did the same with the h-alpha images from previously and have included them below.

Now that is a start, and I just need to experiment to try and get even better results.
