Hst 1990, That famous image... Options

[tedstryk]

I have long looked at this image of Mars and wondered what it might look like. Here is my new version of it. I am working on another image from the 1990 oppositoin.
It is at somewhat larger size than the original pixels (150%).

The HST image was made from Raw data. But here is a 1988 Pic Du Midi image. On the right is the version that is spread across the internet. On the right is my attempt to deconvolve and rebalance it.

Gee, I always liked Percival Lowell's view:



Dig those canals. And this final view:

Tedstryk, what software/method are you using for the deconvoltion?

(Also, you seem to have two right hands based on your post above )

Oops...They will go well with my two left feet. I used a program called Focus Magic to correct focus. It did more for the HST images, since they truly had a focus problem. I also reduced the contrast of surface features in the Pic du Midi image to make it not so cartoonish.

Here is a combined view of the two best views from 1990. There is one partial-disk view from this set that I am still working on - it is the first HST Mars set, but it missed, causing part of the planet to be out-of-field.

[tedstryk]

Here are all three.

For some context, here is a beautiful and very recent (Oct 05) Mars at Opposition HST assemblage from 1995 to 2005, all after repair.

Oppy was just inside the border of the dust storm visible in the center of the 2005 image

This is why it's important to try to get the color balance right on such images. The Mars express Gusev image was initially released with garish green dark areas, and various fools paraded that as proof of green regions on Mars NASA was trying to hide. I had an inadvertent hand in this nonsense when Richard Hoagland stole one of my images to make one of his asinine points. A summary of this saga can be found at:

He stole one of Phils image recently and put 'courtesy of...' . Cheeky sod.

That's the first time I've read of him stealing images.
Is he known for that?

I can't believe how sad he really is.
Just awful.

When H bomb dies, nobody will remember him. Even if one of his theories turns out to be true, his other endlessly silly theories will show he was just lucky. Goodbye, H bomb.

Yes. He does not respect copyrights, three artists I hnow of have had images used on his site and he refuses to remove them. Attempts to reach his ISP have proven fruitless, I wish there was some readily available means to attend to this.
