MARS IMAGES, SEPTEMBER 9th, 2005.
D. A. Peach. Loudwater, Buckinghamshire, UK.
14" (35cm) Celestron SCT @ f/39.5.
Lumenera LU075M CCD camera.
Seeing good (Pickering 7-8.)
Transparency excellent (5.5mag) occ low clouds.
No wind. Heavy dew.
Alt= 35-53 degs.
Here are some multispectral images from the 9th in good seeing. A lot of
interesting detail can be seen.
Over central Chryse a small streak runs NW from Oxia Palus to Niliacus
Lacus which coresponds roughly to the Hydaspes canal. Others may want to
comment. Argyre is interesting showing a cicular outline and dark central
spot. Some weak remainder (possibly of the SPC) remains in the area. A dark
streak is present across Depressiones Hellesponticae. Pandorae Fretum has a
well defined southern boundary. Deuteronilus can also be seen in the early
R images. Also note the weak light channel running through Eos.
In B and G a dense misty NPH is present, and Mare Acidalium can be seen in
places through the mist. Note the dark line bordering the NPH is Blue. Also
in Blue, weak evening mist over Hellas and morning mist over Argyre. A light
MLH is present over Thaumasia/Candor etc.

Phase defect .889, Size 15.4"
Celestron NexStar 11 GPS at 311x & 400x with W23A red filter.
Temperature in mid 70's, very humid, clear, light breezes, no Moon. Solis
Lacus most prominent feature with Tithonius Lacus also dark. Aurorae &
Erythraeum prominent at P limb & Sirenum also dark at F limb. Aonius Sinus
prominent, but not as dark. Nilokeras at terminator in N. Two thin lines
radiating P & F from Solis Lacus seen only in steadiest moments. Argyre
bright, Thaumasia a bit dull, Tharsis brightest region. SPC tiny, but sharp
& still bright. N Polar Hood evident and thin, bright morning limb haze
seen, especially in W38A & W80A blue filters. A tiny bright spot, possibly
at Ascraeus Mons, suspected in W38A filter. Only SPC bright in W58 green

MARS IMAGES, SEPTEMBER13th, 2005.
D. A. Peach. Loudwater, Buckinghamshire, UK.
14" (35cm) Celestron SCT @ f/39.5.
Lumenera LU075M CCD camera.
Seeing fair-good (Pickering 4-8.)
Transparency excellent (5.5mag) low clouds late.
No wind. Heavy dew.
Alt= 48-53 degs.
Here are some images from the 13th in fair to good seeing. Interesting to
note the "hole" in the NPH in the G images. Deuteronilus appears dark in
all filters bordering the NPH in G and B.
In Blue a dusky patch is present where Deltoton Sinus once was. Hellas is
misty toward the evening terminator. Chryse has some light haze which looks
a touch yellowish. Edom also shows a faint mist.
Comments: Morning limb very bright, Hellas area which is about to swing
around on the limb was very reflective and bright. Blue clouds seen on the
NPH - confirmed visually with #38A blue filter.

Last night it was the first really good seeing over the south of the
Netherlands in a long time. I took many IR-and blue images with the
ATK-1HS and some IR and color images with the ToUcam. Here is one of
the IRGB results taken with the ATK attached to a 10 inch Newton at f/60.
The NPC was already large in the blue light and very obvious visually
with a nice cyan color. Visually impressions were excellent, especially
with a 3.6mm Super Plössl oculair at 333x.

Attached is one of the near infra-red image I took on Sept.13.
Note some small 'canals' between Hellespontus and Noachis.

An animation of Sept 13 images showing the differences between an IR and
blue image. Note that Novus Mons is still appearing and the dark line
which is visible in the IR image corresponds with Ismenius Lacus, just below
the North Polar Hood. A small dark spot appears in the blue light in the
center of Sinus Sabeaus. South is up in this animation.

Here are some further results from my Sept 13 observing session.
