Hi all, here's an image of Saturn
from last night in reasonable seeing using a 650nm longpass
filter.
A number of faint cloud features can
be seen on the disk. Rhea can be seen to the left of the rings.
8 images spanning 12 minutes were
measured and merged in Winjupos.

Hi all,
I fear the persistent seasonal afternoon winds, which are peaking
just around the time I am wanting to image Mars, will
draw this apparition to a close for me.
Almost impossible to attain a decent focus,
and stronger winds are forecast in the coming days. But I will continue to
check.
M Acidalium and Niliacus L may just be made out at lower right. The bright
Arabia/Eden region dominates the view to the left. Whilst Sinus Meridiani may just be detected,

Hi all,
I wasn’t expecting to image yesterday afternoon, with cloud
forecast. However, there were significant gaps, which allowed me to run a
series of captures.
The view is centred on Chryse with
Niliacus Lacus and M Acidalium
below centre.
Nilokeras can be
seen to the right of Niliacus L.
M Erythraeum extends across the
upper section of the planet with Aurorae Sinus upper
right of centre.
Sinus Meridiani can just be made out
on the left limb.

A frustrating session with some hectic late afternoon winds
peaking before sunset.
The view is centred on Xanthe.
Solis Lacus is at the upper right of the image with Valles
Marineris extending above centre towards the right.
Aurorae Sinus

Niliacus Lacus

I must admit, I am pleasantry surprised that the typically

detected.

Hi all,
After a few afternoons where cloud prevented imaging, I was again
able to find Mars well before sunset.
The higher contrast features certainly assist with trying to
attain best focus.
Solis Lacus is at the top of the image with the Tythonius L section of Valles Marineris above centre.
Aurorae Sinus
is upper left of centre, with Nilokeras to the lower

Olympus Mons is just to left of centre but not clearly detected (possibly in the

Due to the poor quality of the G and B data, the RGB should

Hi all,
After a few afternoons of cloud , that thankfully also brought our first, albeit limited,
summer rainfall, I took a chance on Mars this afternoon despite winds gusting
up to 10m/s.
Understandably, imaging was
difficult, and I could only capture a few R610LP SERs
The view is centred on Amazonis, with Mare Sirenum
across the top.
I note that Mars has finally slipped
below 4”.

Hi all, here's a heavily enhanced
Saturn image from Rubyvale last night using a 650nm longpass filter in good seeing. 10 images spanning 19
minutes were combined to get this result.
Many cloud features are visible, including what appears (?) to be a lighter
recirculation system
down south near the centre of the disk.
Also a prominent dark feature is
visible in the southern hemisphere closer to the SEB as well as many
festoon-like structures in the equatorial region. The long-lived white spot is
visible at lower right.
The moons Tethys and Rhea are visible close to the
right hand edge of the rings.
Tethys is just above the ring and visible only as a tiny
extension to the ring while Rhea is below the ring.

Hi all,
Another pre-sunset image set from yesterday afternoon.
The general trend of reasonable RLP and R, “so-so” G and
poor B continues.
The B likely negatively affected by the altitude, build up
of light afternoon cloud and lower transparency due to wildfires at this time
of year.
Mare Cimmerium is across the top,
with Hesperia at upper right. Unfortunately I could not pick out the Sinus Gomer extensions.
Light(RLP/R)
Elysium is just to the left of centre. Trivium Charontis and Cerebus may be
detected.
I was pleased to see the familiar Amazonian giant “?” to the
left of Elysium, best seen in the RLP
Propontis I is to the lower left of Elysium.
Propontis II, Stymphalius L, Gyndes, Sithonius L, Panchaia, and Utopia are across the bottom.

Hi all,
Image set from yesterday afternoon, about an hour before
sunset.
R and RLP remain decent. The B was extremely low contrast,
likely due to light cloud that I noticed as I closed up at the end of the
session (still well before sunset). As a result the RGB may be somewhat
inaccurate, but I include for aesthetic reasons.
Syrtis Major
is on the right limb with Mare Cimmerium/Tritonis
Sinus above centre. Hesperia and Syrtis Minor are to
the upper right. Boreosyrtis (lower right) and Utopia
are across the bottom, separated by the light Umbra. Elysium is to the left of
centre.
As mentioned above, the RGB may be inaccurate due to the
poor B, and I am wondering if the RLP/R don’t hint at
the appearance of the SP Hood. But I certainly cannot be sure.

Hi all, here's an image of Saturn
from Rubyvale last night in poor seeing.
The 807nm longpass
filter was the best choice in the conditions and it shows some detail around
the equatorial region and a compact bright storm in the south.
Note the distorted shape of the
rings as they pass in front of the globe caused by the large amount of image
enhancement needed to bring out the details on the planet interacting with the
curved ring shadow.
