June 21th, 2003
In the image of Neichi, the white cloud of Tharsis (95W,+10) is
clearly recorded. Also, the North Pole, too, is covered with white
fog. Hiroaki Akutsu is recording the state that darkfringe became
thick. Cristophe Pellier recorded the state that cloud can be
still seen in the east of Syrtis major(290W,+10). However, as for
this cloud, the way of falling is quite different when the
photography condition is different. Tan Wei Leong recorded the
state that Trivium Charontis(200W,+20) becomes a black point. As
for Erysium(215W,+20), yet, cloud doesn't come out. Also, yet
cloud can not be seen in Nix Olympica(125W,+20), too.

The resolution of works sent from the foreign country is wonderful.
The antarctic dark part could be seen.

Hi all : this morning the seeing was good and the transparency excellent.
I've been able to make three series of images ; and for the first time I've
managed to get a correct image with a "normal" color avi file of the ToUcam
despite the low altitude of the planet.
Note that the three blue images all show clearly the dark markings of the
planet.

Dear friends
The sky has been clear again and I managed to obtain some mars images
Attached is the mars image from this morning.

Transparency was poorer this morning 6/10 and seeing was 5/10.
I had to reduce the F ratio to f/60.8 (2.5x powermate + 2x barlow)
Stacking of 1000 frames out of 1800 frames at 1/25 sec gain at 60%
There are a few other avi that I will get to process later and they
will be send out in due time.
Clear Skies to everyone.
---------------------------------
Attached is an additional mars image from 21st June 2003.
This image is done with the true tech magneta filter and IR blocker.

The main difference between the UV-IR filtered image and with the
UV-IR+magneta filter is the lack of green ghost (surface details)
in the B frame as well as no saturation of following limb in the Red frame.
The raws are much easier to process.
This method with the magneta filter works as expected according to the article.

These images were taken Saturday morning in good seeing.
Quite a bit of detail visible in these. One of my best Mars images.
Approximately 120 images were combined to make each of these.
The RGB image is with a synthesized Green image by combining the R
and B to make an average.
Thanks
