Hi Mark;

Thanks. Sinus Iridum shows some really interesting features. The north (top) edge has an interesting radial fault (probably Imbrium related) that I haven't seen mentioned before. I also shot a long strip last night along the "DomeZilla" area west / left of Copernicus that I hope to process tomorrow.

As to your question on the my color exaggerated Luma  images.

In the images

and

The left image is the the original source movie, which is basically a grayish brown color. The right image is what I get after I increase the saturation which enhances the subtle colors. Those were done in the Image Processing window of Astro IIDC by setting the Saturation to between 3.0 to 5.0 range and then adjusting the Red, Green and Blue Gain values in very small (0.01) increments. A tiny amount of change can have really drastic changes in color changes when the saturation is that high.

The Lunar images that you posted look very red-orange. Is that how they are originally or is that done in processing? If that is how they were shot, then it will be very tough to generate the exaggerated color images like I have, because the colors are off to start with. So basically they have to be color balanced properly when you shoot them or it likely is not going to work.

As to the bluish craters you mentioned, without seeing your stacking log text file to see what options you used, my guess is your cranking the "Sharpen frames by xxxx amount before stacking them." (see page 32 and 33 of the manual)  pop up menu to some high amount? Don't do that or it will produce artifacts. As it says in the manual for using this option "For high contrast objects (i.e. lunar terminator, solar limbs etc.), you should not be using more that "Very Light" sharpening."

Hope that helps..
