Why did they send Hubble when there is one down there :)
I saw a lot of amazing photos but this is the most far superior. Bravo!!!

Fantastic amount of nebulosity. Hypnotic eerie colors. And hey, I spotted the Easter Bunny at bottom center - watch those ears!

Your images of Orion are absolutely stunning! Unfortunately the JPEG compression you used almost turns the stars into squares. Any chance of getting a higher quality version?

Thanks for all the nice comments!

Marc, I do have higer-res versions of some images. I usually save those for printing purposes or other projects. In the case of this image however, the highest res version you see is the highest res version there is (other than being in uncompressed form). Unfortunately, back in the "old" days I wasn't so careful about preserving high-res versions of my images, and most of them ended up reduced in size during post-processing, and so the final version was also reduced in size. I no longer do that, but there's not much I can do about older images.
