Looking good Dave!
It's indeed a kind of specialized way on how to approach it.
And I don't know if I mentioned this already: with capturing the moon with a mineral moon processing in mind, it's best to be a bit on the lower side in the histogram than normal. For this one you were on Mean 57, so with a next try you could go for example to Mean 50 or maybe lower. This way you have some more headroom in processing because the color saturation is a kind of stretching.

Thanks Menno. I will try with a lower histogram next month (moon is very low for me now).

"...Microsoft Image Composite Editor stitching results in the greenish images..."

When I saw this I did a double-take. Then raised an eyebrow. I've been using ICE all the was back when it was supported by Microsoft. I never noticed the green tint. And it's not subtle.

I used this stock photo to test. I created two mosaic panels and then merged them. The left image is the mosaic stitch by ICE while the right is the original.

The result was a blue/red suppressed image. It's most notable on the left cheekbone of the woman on the left.

I stumbled on some image size oddities in ICE, too. I need to look closer at my process on the split image here and dig into the other oddities. If I find something meaningful, I'll post on Cloudy Nights.

Thanks for making me aware of ICE's bug.

Thanks for the info. The image you posted demonstrates that not all is well in the application. The info I posted came from forum user @Menno55.

This was my first attempt at colour imaging of the moon - all previous work has been with mono lunar mosaics.

If you do find out more can you leave a link here to your Cloudy Nights post.

Thanks.

Dave

I have revisited this.



The left hand image is the one from post #9 and #10 above. The right hand image was re-processed as follows:

• Stack best 10% of 825 in Autostakkert!3

• Stitch 2 panels with Microsoft Image Composite Editor

The next steps are all within PixInsight:

• Deconvolution, St Dev=2.0 & Iterations=20

• Range Selection to create mask

• Apply inverted mask

• Curves to brighten, 2 applications

• Apply Local Histogram Equalisation

• Curves to increase saturation, 4 applications

• SCNR to remove green caste

This image has better control of the brightness in the southern region and stronger colour of the minerals.

Wow, Dave, what a difference!

Those PI tools working really well! A cleaner and better coloured image

Thanks for the comments Brian & Tim.

I use Registax to saturate the colors of the Moon.
