M51 before and After

My first object with my new STF-8300m camera was M51. I previously posted the following image of it.

I have been working with the trial version of PixInsight. It is quite a learning curve. I had already reprocessed M-57 and like my new result much more. Today I spent a couple hours reprocessing M-51. This is the result. It is certainly different. At first, honestly I preferred the original. However, the new version is growing on me. They certainly are distinguishable.

I like the first version, and looking at it briefly, I think you can boost the saturation and bring more color out in that one. I think the 2nd version has gone a bit blue. Details look good in the galaxy.

I also like the first version - however, you can benefit from both by using Layers and Masks in PS and take the good stuff from the first (Such as the 2 cores,,,) and replace them in the second version...

Cheers,

I agree. You have a very flexible saturation tool in Pix, and I'd use it on the color version, to later add to lum.

Hi, the first image is much better. Pixinsight is a very powerful software and I use it for 80% of my processing. However, I find best PS for some basic steps as color balance and selective contrast, using layer masks appropriately positive and negative. These specific tools are very, very powerful. Your images suffer from gradients which must be removed, furthermore are not balanced in the color channels and the sky background should be neutral, but instead has dominant colors. I downloaded and corrected your first image, eliminating gradients, balancing the channels and highlighted the fine detail with layer masks. Also, now, the sky background is neutral, as it should be. Download the image and look at the histogram of the 3 channels as it should be. Keep in mind that this was done only with PS from your JPEG, accordingly with compressed data, therefore not suitable to make a good processing. I hope this can help you in your next processing.

Thanks Marco. Your version if definitely the best of the three. That definitely gives me something to shoot for when I give this another go.
