Lunar crater Plato in deep shadow
Sketch and Details by Giorgio Bonacorsi
Hi sketchers,all o.k.?
Last week, after bad weather days, the sky was clear and i decide to use my refractor 80/1000 for Crescent Moon. I placed my refractor in front of my home and the Moon was just over the trees, in this moment is very low but i can’t help drawing it.
I observe in eyepiece at 47,6x and decide to use 6mm lantanium for Plato and i made this sketch.
I hope you like it.
At next,clear sky at all.
Ciao,Giorgio.
Site:Pergola,Marche,Center Italy.
Moon phase:Crescent
Instrument:Refractor Kenko 80/1000
Eyepiece:6mm lantanium
Magnification:166x
Seeing:Good,no humidity no wind.
The dying star, Eta Carina
Sketch by Serge Viellard, text by Frank McCabe
During his vacation trip to Namibia in March of 2009 with the 400cm. travel scope at high power, Serge captured this close up sketch of the asymmetrical orange lobes on each side of the dying star Eta Carina. Serge writes, “This sky is really extraordinary. I have above my head the most remarkable 3 nebulas of the sky with Orion beyond the zenith…”

Quite an old sketch of barnard’s galaxy (very faint and fuzzy, but not so distant dwarf galaxy, where you can resolve individual star formation regions)
Lunar craters Schickard and Lehmann
Sketch and Details by Jeremy Perez
It’s hard to get used to the fact that the moon plays misery on DSO observations two weeks out of every month. I can see that my biggest interest leans toward those dim patchy things, but given a little time exploring the moon, it still turns out to be very rewarding. So I took some time this bright moonlit evening to explore some likely craters listed in the Astronomical League’s Lunar 100.
Schickard is a large crater on the western limb of the almost full moon. There is an intersecting crater on the north end that looks about 20% as big.The southwest floor has a series of ridges or cracks that run northwest to southeast. There is also a half-circle of craters on the western floor. On the east side floor, a distinct white patch is visible.
After getting past the dazzling array of contrasting crater-wall shadows, I noticed to my surprise that the floor of the crater gave the appearance of a monotone scoop of Neopolitan ice cream. The north half and southeast tenth of the crater floor were darker than the rest of the floor. These three distinct shaded areas didn’t owe their differences to some lucky angle of light, as their boundaries ran roughly parallel to the angle of the sun. Also very noticeable was a rough jumble of terrain outside the crater along the west-southwest rim. It was tough to sketch that and make it look like it belonged to the local terrain without spending an eternity linking it to continuing terrain further west. So it is what it is.
Factoids:
According to the The Moon Observer’s Guide, Schickard is one of the Moon’s largest craters at 227 km in diameter. Its walls rise 2500 meters above the floor. Its southwestern floor has been noticeably disrupted by debris thrown from the Orientale impact over 1000 km to the west. This debris carved valleys and chains of craters along this part of the crater. Periods of lava flooding have given the crater floor a multi-toned appearance with darker sections in the northern and southeastern sections–the most striking example of this on the Moon’s face.
The crater intersecting the north side of Schickard is Lehmann Crater. Lehmann is 47 km wide (20.8% the width of Shickard–hahah!) with 800 m walls.

Hi,
While I had been observing the sky between 1.30am and 2.00am on
21.06.2009. I saw something that amazed me. When I had been looking at
Jupiter I wasn’t able to find Io…, than I understood – it was hidden
behind Jupiter! I had been waiting untill Io showed itself. It was a
magnificent view!!! I just loved it!!! Here is a sketh that tries to
show You what I saw. I hope You like it.

This morning, I moved the solar rigs outside for better seeing
conditions. After all the rains and then full sun today, the coolness
of the grassy fields would be a significant improvement over the hot
wood and carpet from inside the observatory. It appears my decision was
the correct one because I started the solar session off with h-alpha and
was able to not only increase mags to a 7mm, but used a 2.5x Barlow
toward the end of the
h-alpha session for deeper observing. The seeing became much worse
about an hour later when I began my white light filter observation.
Both active regions were obvious and 1023 almost looked like an “X”
shaped plage with a hint of a spot to the western crook of it. There was
another plage on the other side of that spot with a very prominent
filament reaching to the west, although very small with a more obvious
spot at the eastern start of it. Moving west across the disk, AR1022
was almost a “U” shaped plage resembling a pair of oxen horns with the
way each side of it curved outward.
There were many prominences, all fairly small, but they popped in and
out as I moved the Sun in my FOV for optimum clarity of features.
Speaking of the tilting of the Maxscope’s Etalons, I observed with Alan
Traino at a star party this weekend and had the chance to use a pressure
tuner on their 60mm Lunt h-alpha scope. What a great design! And I was
very impressed with the flat FOV, making it so much easier to pull out
details. Thanks Alan for supplying the scopes for us to try out. Wish
I had had more time to play with the pressure tuning scope as well as
the CaK.
The solar disk was speckled with network details and there were several
filaments, although again, very slender or very small.
The view with the white light filter was a little harder to discern
because of the dramatic change in seeing. Although I got a good focus,
I only had slight moments of seeing to make out a little bit of detail
within AR1023. What first looked like two oblong sunspots in that active
region became two pairs of sunspots. The preceding pair was the larger
with the following pair the smaller. There may have even been a third
little spot in the preceding pair but seeing prevented me from really
honing in on those two sets. There were no faculae that I could make
out, although there was a hint of contrast around both sets of spots as
well a faint line reaching from the preceding to the following pairs.

Hi,
This is International Space Station. I made this sketch on 15.05.2009. I
have seen solar panels, it was a wonderful view!
