20030718 (my best mars taken under good seeing)

Dear friends,

Attached were a set of mars images taken in this morning. I use harder
processing for the shot taken at 20:36 and the other two with "natural"
processing. Those are my best so far. The south pole cap shows very complex
structure!!!

Great job. I especially like the 17:41 photo. Is that Valis Marineris
(sp?) in the
center?

The hard processing on 20:36 appears to introduce a ghosting artifact around
Syrtis. Is this your perception as well?

Cheers,

Hi Larry.

Thank you for your kind comment. :-)

The 17:41 shot is showing the region of around CM=230 degree and the Valis
Marineris should be location at the region of longitude around 80 degree.
that means almost opposite side of my image. :-)

For the Syrtis major ghosting "artifact" you have pointed out, that is real
detail. I am attaching the image I took on 17 July with very soft
processing, the "ghosting" features you mentioned was still there especially
bright in R channel.

I am attaching the link of an interesting sequence of 1994 mars shots taken
by HST and you can see that too. :-)
