I send one original image from Mariner 9 (mosaic is from three images), so you can compare original and result.
Images are improved so, that I'm trying preserve original usefull information and remove noise and reseau marks. Especially in widefield Mariner 9 images is problem with horizontal errors. Color is entirely artificial, just for better look. -------------------- |

What is your source for the raw data? The one above looks much better than any scan of a print I've seen.

I didn't realize that the data that old was available electronically. Good work. I wish I had the time to try some of that.

I think that these images are oldest electronically available on internet.

I remember that mosaic well! I think it was on the cover of New Scientist at the time. It was the first ever full-disk (almost) image of another planet which showed dramatically more detail than a telescopic view, so it made a big impression on my 15-year-old self- it made Mars suddenly seem very real. It never looked this good back then though- nice restoration job!

No, the digital Mariner 6 and 7 images are available here: http://ser.sese.asu.edu/M67/mar67.html Phil -------------------- ... because the Solar System ain't gonna map itself.

The Mariner 6-7 images on that site have a few issues, but they are pretty good. If I ever actually have time to work on an image again, I need to finish my Mariner 6 and 7 set. Here is my recent blog post related to this http://planetimages.blogspot.com/2009/09/m...ni-in-1969.html

Thanks!
Especially in this case, I have strong inspiration from your images. Your works based on Voyager 2 images are amazing! -------------------- |

The Mariner 6-7 images on that site ( http://ser.sese.asu.edu/M67/mar67.html ) have a few issues, but they are pretty good. I have many objections to this web page, image gallery is incomplete and unsystematic. For example, I can not understand why there no picture 6N01. Secondly, images 6N02 and 6N03 (for example) are at different stages of processing. Properly it should look like this, showing the successive stages of processing: 6N01 6N02 If they are presented only selected images, all images in the gallery should be on the same stage of processing. You can see how great the differences in the various stages of processing. -------------------- Free software for planetary science (including Cassini Image Viewer).
