Posidonius: a FFC crater

This is a sketch of the crater Posidonius made trought my 6” achromatic refractor (TS Individual 152/900), binoviewer, a pair of 10 mm eyepieces (BCO´s) and Barlow that gave me 330x. The seeing was very poor at the beginning of the session but it was improved until I could get very stable view of this formation.

Posidonius is a beautiful crater that can be classified as a FFC crater (Floor Fractured Crater). It has several fractures on its floor that can be observed with small telescopes, and also the amazing Rima Posidonius, a lava channel that crosses the crater from north to south on the eastern part of the crater. The origin of this kind of FFC´s is controversial but the modern theories suggest that a magmatic intrusion below the crater bulged and fractured the floor.

The complex pattern of the shadows and the variety of characteristics and formations inside Posidonius make this crater a very interesting observation target for any amateur astronomer.

I hope you to enjoy with this sketch.

Mooncrater Krieger

Lunat crater Krieger-March 13, 2014 — Lunar crater Krieger-March 13, 2014

Hello friends of the dark side,

Last week we´ve had some good conditions to observe the moon and his fantastic craters. Near the Schröter-Valley I enjoyed the sight of the crater Krieger.

I hope you like it too:

Aristarchus, Prinz and the Harbinger Mtns.

Aristarchus, Prinz and the Harbinger Mountains-June 20, 2013 — Aristarchus, Prinz and the Harbinger Mountains Region-June 20, 2013

The kilometer high rim of Prinz (47 km.) crater was casting a shadow across its own lava flooded floor. The uplifted Harbinger mountains were also casting fine shadows in this region of the lunar surface with its large magma ponds pushing up and freezing in the distant past. The uplifting doming in the region created many fissures for lava escape and flooding to occur. The fissures can be seen clearly on nights of steading seeing. I was denied that detailed view on this night. From the crater Krieger (22 km.) north and somewhat east of Aristarchus (40 km.) four distinct long shadows could be seen crossing to the 70 km. fault called Toscanelli at the edge of the Aristarchus plateau where the terminator was located during the rendering of this sketch.
A fine view in any telescope.

Structural detail of the Pythagoras central peak

Structural detail of the Pythagoras central peak-January 15,16 2014

On two nights with more better seeing and sunlight angle or libration , I could see these views.

See below 2nd sketch over on the lunar horizon as the border with a line of the imaginary inner rim wall of this 130km diameter crater a bluish 10 mignitude permanent star was being moved on from over the Pythagoras to the Anaxagoras (Pilalous) in 4 minutes, …. that I think means moon and earth twin bodies each was(are) rotating and revolving.

It was thrilling to gaze and feel this massive giant old rocky ball goes ahead swinging or pitching his body in space.

Montes Caucasus

Object Type: Moon
Location: Barcelona – Spain

I don’t observe the moon as much as I would like. It’s a shame, because when I do it, I always really enjoy it. On the seventh night of lunation, the Montes Caucasus shadows are really exciting. I would like to know how to draw better to capture what I could really see that June night. It was amazing.

For more details of my observation you can visit my blog:

Thank you and best regards.

Lambert & Mons La Hire

Made this sketch of crater Lambert, Mons La Hire and Dorsum Zirkel and surrounding areas this evening, using my 505mm mirror and Watec video camera on its least sensitive setting. The view on the monitor was delightful and one I shared with optical designer and engineer Mr Es Reid of Cambridge, all very civilized and enjoyable.

The sketch was made on black A5 220gm art paper using Conte hard pastels and acrylic paint for bright highlights and deep shadow.

I hope you like it.

Kind regards, Dale

Posidonius

Hello,

Posidonius is the result of the first 20 minutes of my “moon observing night” at 7th. January 2014. A dense cloud cover moved on after that.
Deep black sky, spring-like temperatures, ordinary air peace and beautiful details on the moon … and then it was over.

Well, the “coarse drawing” was finished yet. Unfortunately I brought the many fine details that were clearly visible, not on paper.
Nevertheless, I am satisfied with the drawing. Hope you like it too.

Gassendi and Region

Gassendi and Mersenius Craters - September 17, 2013 — Gassendi and Mersenius Craters – September 17, 2013

Hi,

Please accept my sketch of Gassendi and Mersenius craters and surrounding region. I created this sketch from my backyard in Green Bay, Wisconsin during a night of rare excellent seeing. Its a very interesting region of the Moon just off the boarder of Mare Humorium. I made the sketch using my 10in Discovery Dobsonian telescope at 170x with a neutral filter. For this sketch I used white paper with 2H, HB and 2B graphite pencils and blending stumps to smooth. I hope you enjoy it.

Object Name – Gassendi and Mersenius craters
Object Type – Lunar Surface
Location – Green Bay, WI
Date – Sep 17th, 2013

Equipment – 10” Discovery Dobsonian at 170x. Neutral Filter.

Crater Agrippa

Hello friends artists,all ok?

after many days of bad weather,yesterday i have clear sky(only some
little clouds).The Moon was at zenith over my roof at first
quarter,behind my home Orion giant,Jupiter near zenith.
Clear starry sky and good air are good after work day….
I mounted my refractor Vixen 90/1300 on terrace and i take my eyepiece
12,4mm erfle,the image was steady and i decide for 12,4 plus barlow for
much magnification…..and,after,i decide to take my 3mm planetary.
At first the image was steady but, after 30′ turbulence and clouds
disturbe the clear and steady Moon ……i stopped my sketch……
Well,good night for me!!
I sent to ASOD and i hope like you.
Ciao a tutti!!
Giorgio
