MARS IMAGES, OCTOBER 27th, 2005.
 
D. Peach. Loudwater, Buckinghamshire, UK.
14" (35cm) Celestron SCT @ f/40.
Lumenera LU075M CCD camera.
 
Seeing very poor (Pickering 2-3.)
Transparency very good (5.5mag.) occ clouds.
Wind S (5-10mph.) Moderate dew.
 
Alt= 48 degs.

Here are some images from the 27th. Very poor seeing. The blue syrtis cloud 
seems to be present in this set of images though i didnt verify it at the 
eyepiece.
 

Here is a set I took last night almost midnight my time.  I have been watching 
the dust clouds develop with much interest through many of your images.  On 
mine this morning I note the notable dust band in the South visible in all 
wavelengths suggesting the dust has reached the upper atmosphere. It does not 
appear to have yet reached Hellas in my opinion, based on the fact that the 
band in blue does not go that far.

I do note some disturbances in Oxia Palus, Margeritfer Sinus, Mare Erythreaum 
and perhaps Chryse.  There are hints of obscuration in the green and red image,
but not blue.  Mostly however, I note a haze over the entire region, notable 
on the RGB image resulting in reduced contrasts.

Some dust in the southern regions of Chryse does appear, although seemingly 
thin; this spreads southward.  Interesting diagonal "wave of darkening" seen 
in the northern regions along with some high think N. Polar haze...  Overall 
pretty variable seeing conditions persist; there are very brief moments of
incredible clarity, but only on the order of 3-5 seconds maximum.
