That's very good, Bart.

The subtle detail in the body of the Swan came out very well, and drew my eye to a feature I'd never noticed before. As well as the famous near-black square in the concavity of the swan's neck, there's a larger, much less contrasty, but more perfect and complete square just to the right of the swan's bum, say at 30% of the way toward one o'clock from image dead centre. The subtly dark square is rotated about 30 degrees. There is a chance alignment of faint stars pricking out the edges of the square, making it look more salient. The Meyer Square!

Nicely done!


Best,
Mike

Great details but I reckon it has a red bias. Have a look at that widefield. Heaps of color variation.

We could always do better, but that's a nice image

Thanks Mike. I like the Meyer Square, sounds good. I must admit that while looking at it I can see the detail although did not pick that up until you mentioned it.

Thanks! The luminance image is quite good in its own right, maybe even better than the final colour version.

I'm inclined to agree somewhat Mark. Thanks for the reference image.

You are so right Rick, and as long as we do, we will grow.
