Hi all,
Not the
best of seeing this morning, but also not the worst.
A familiar face of Mars looking straight down on Syrtis
Major and

Hi all,
I came
close to aborting the session this morning due to poor seeing and then suddenly
found a short period of decent conditions, allowing this image set produced
from single IR, R , G and B captures.

Hi all,
Conditions
were not as good this morning.

Hi all,
It was
nice to be back on the farm and in the observatory this morning, following a
week in
Conditions
were nice, although I had overslept and this is from a single set of data only.
S.
Sabeaus and Meridiani extend across the centre of the planet.

Hi all,
Mars
image set from this morning. Solis Lacus is above centre with Valles Marineris extending
in from the centre left to the centre. Nilokeras may just be detected at lower
left.

As a
side note, after the Mars session and before slewing to Venus, I was able to
find Saturn at 12 deg altitude and brightening sky using the IR685 filter.
Unfortunately not enough contrast to produce a result. But I anticipate
starting Saturn imaging soon.

Hi
Rima
Austaleus if that is what the dark streak was on the cap would have rotated to
the back side of the cap making it hard to see.
Hey,
what happened to the infamous dark ark?
Don't
change any camera settings or it might reappear.
Good
seeing,
Jim

Hi all,
Despite
poor conditions this morning, there was some slight improvement towards sunrise
which allowed this image set.
M
Sirenum is at upper right, with Solis Lacus upper left of centre. The Valles
Marineris complex extends in from centre left and is just detectable in the R
and IR.

Hi
observers,
The
streak might be Rima Australius based on a map of the SPC in the Mars
Observer's Handbook.
Good
seeing,

Though
less optimally seen on March 11th, the dust streak persists.
Thanks
for your continued monitoring of Mars,

The
split in the SPC is possibly a dust streak. This occurs occasionally.
Usually
is can be seen for longer than a day, up to a week perhaps.
Let's
see how long it lasts.

Hi all,
Conditions
were a bit better this morning, and I was able to catch Mars earlier, at least
giving me some better B data.
Mare Sirenum
is above centre with Amazonis extending across the centre of the planet.

Hi all,
Morning
conditions have been poor over this last week (when there has been clear sky),
and yesterday morning
was no different. They did improve a bit towards sunrise, but this made B
captures difficult and the B, in my opinion, is of no real value, although I
have included it for the record, and I did use it to put together an RG(B), as best I could.
I note
a possible rift in the SPC in the R image, but given the conditions this would
need to be confirmed by other images. Anyway, I hope this gives some indication
of the planet.

Hi all,
Mars
set from this morning.
M
Cimmerium is the dominant dark feature above centre. Elysium is at lower
centre, and I believe that Cerebus may just be detected, best seen in the R.
Thanks
to those that constructively commented on my previous image set, and I tried to
take a bit more care with the processing.

Hi all,
Mars 1 March. A very pleasant session towards
sunrise this morning, with what looked like some fairly decent seeing, despite
the altitude.
As I processed,
I realised that I might have a challenge, as the G (in all captures) showed a
bright limb. So I have presented two results.
The
left hand colour image is an R(G)B, produced by
generating a synthetic G from the R and B data. This to a large extent bypasses
the bright limb in the G. The second colour image is a true RGB, which shows
the impact of the bright limb in the G.
I am
open to comment and correction, but I suspect the limb brightening may be a
result of cloud along the limb that is exacerbated by the processing?
M
Cimmerium is at upper left, with M Tyrrhenum at upper right. The two are
separated by the light Hesperia at upper centre. Elysium is at lower left.
