Object Name: Gassendi
Object Type: Lunar Crater
Location: Dunboyne Ireland
Date: 4th October 2014
Media: Graphite pencil H2, H3 & B6 with standard white stock and technical drawing equipment.
This is actually sketched as observed through the eyepiece with a 15mm on a 9.25 SCT rather than from the phone screen. The seeing was fair but a weather front was fast approaching and just managed to observe long enough to capture this detail. At the same time I took some snapshots through the eyepiece with my smartphone for a smartphone astronomy site – so got to do both before the clouds rolled in. Adding the phone to the sketch allows me to add a technical drawing into the mix which I not (only) enjoy but also allows me to capture the evenings activities and optical equipment used during the session.

After outlining major features using solid lines, dotted lines and numbers(1-9) are used to express gradation in brightness(right). The numbers are replaced with “real” darkness after the lines are copied on another paper (left).
last week (October, 3rd, 2014) I met my astro-friend Ralf Mündlein in his nice observatory. In his 5m dome with 16″ ACF and 8″ Apo we started our observation. First object in this night was the moon. The air was excellent and we were very happy to have such great impressions on our cosmical neightbour.
A chose the nice crater Wilhelm with some bigger impacts around the craterwall. A fine mountain chain at the bottom of the crater took my attention. So I made a drawing of this crater with the 8″ Apochromat. It was hard work, because there were so many details. I needed nearly one hour to catch the whole crater.

A conjunction of the Moon and the planet Saturn – September 27, 2014
Aloha!
I had plans to go to the summit of Haleakala to observe the occultation of Saturn by the Moon, but clouds and wind kept me closer to home. I was delighted when a patch of sky opened up and I could observe the wonderful phenomenon from home.
As I was observing Saturn get closer to our Moon I was struck by how small it appeared in comparison, appearing the size of some of the smaller lunar craters. I began sketching in the details of the Moon and noticed a few stars I wanted to include. I needed to do some erasures because one of the stars was occulted ~15 minutes before Saturn, an unexpected treat. Once Saturn made it to the limb I could not clearly time the initial ingress as conditions began to deteriorate. It was however brilliantly lit in comparison to the dark lunar limb. I noted time as 19:41:36 HAST when all evidence of Saturn disappeared. My sketch is as Saturn had partially slipped past the limb. I was unable to view egress as the Moon had slipped behind clouds by this time.

Lunar crater Pitatus and environs – September 17, 2014Lunar crater Pitatus and environs (labeled) – September 17, 2014
Pitatus is an old, large 97 km. diameter crater on the edge of Mare Nubium. The floor of this crater has a linear central peak which was casting a fine elongated triangular shadow at the time of this observation and sketch. To the south craters Wurzelbauer (88 km.) and Gauricus (79 km.) could be seen; both of these craters show badly warn rims; both much older than Pitatus. Attached to the northwest rim of Pitatus is the crater Hesodius (43 km.). At about the eighth or ninth day of lunation you can observe the famous “sunrise ray” beaming across the floor of Hesodius through a break in the wall with Pitatus. This is certainly a sight worth observing.
Sketching:
For this sketch I used: Black Strathmore 400 Artagain paper, 12”x 9”, both white and
black Conte’pastel pencils and blending stumps.

Lunar crater Gassendi and the the northern part of Mare Humorum – September 5, 2014
Here is a sketch of the Moon on the 5th of September from my backyard
in Adelaide, South Australia.
The moons phase was waxing at 83%, with only the very western edge
still in shadow. I observed with a C11 SCT. Seeing was quite
reasonable, so I took a 15mm eyepiece + 2x Barlow for a close look.
The shallow illumination on Mare Humorum made the creases on the mare
floor stand out. Crater Gassendi, toward the bottom, showed stark
shadows. Rimae Hippalus was visible, passing through the partially
submerged crater Hippalus at the top right. Because I used a diagonal
prism, the sketch is mirror imaged.
I used pastel chalks and black and white pastel pencils on black
paper.
Dorsa Euclides and the lunar crater Euclides – August 6, 2014
Dorsa Euclides F and Euclides
Object Type: Moon
Location: Tarragona – Spain
Usually it is not easy for me to draw the moon, and if I have to draw something as delicate as lunar wrinkle ridges (dorsa / Dorsum), things get complicated. But the time I spent enjoying Dorsa F Euclides, Euclides and the neighbors ghost craters worth it.
For more details of my observation you can visit my blog:
Among the large craters of the lunar southern highlands, a nearly 4 billion year old crater stood out over the terminator on this evening just after local sunset here in the central USA. This crater is the 230 km. diameter impactor known by the name Clavius. Clavius is blanketed with a sizable number of craters and numerous craterlets . The north-northeastern rim of Clavius has a large crater resting upon it and most of its rim is just catching the light of sunrise. This 52 km. diameter crater is Porter. Much of the central floor of crater Clavius remains in darkness except for Clavius D (21 km.) and to its right in the sketch Clavius C (13 km.). Note that crater D is casting a nice shadow across the high central floor which is just beginning to light up in the lunar morning sun.

I hope,have to correct my previous ASOD posted that sketched on 11,11,2011 [ The Chevallier crater ] as to [The Zeno crater] ….. in the begining month of this year I found this name in Wiki and now most probably this split rimed crater,s name is maybe “Zeno” . The LRO photo shows a 5 km diameter criminal impactor crater vividly laid on the demolished and streamed down rim-wall that I think must be made of reratively soft weak meterial or even I think the small impactor crater was not ” the a criminal ” for this dramaticaly split rim of Zeno.
This 60km diameter crater is located near the Moon,s limb upper Mare Crisium and looked always long slender elliptical shape. For the first time I saw it accidentally with my 8″ dob on excelent seeing night on 10.25, 1999. Second time,with my 8″ refractor on 11.11,2011 , and now I have 10-12 night observations for this interesting crater.
The bottom in my sketch , a inserted 8″ dob,s old sketch shows a small convex hill between split rims of maybe over 2-4km height and that was sketched also as a more impactor crater like in my other 8″ og observations at more favorable librations but even yet where I did not certain whether it was the impactor crater or a massif hill ,barely visible.
The 16″ dob sketch shows the Zeno with it,s environs well, When starting 13″ og observing after 16″ dob , the shadow of the strong jet-stream flow over 20km upper atmosphere passed through on the lunar disc from north pole to south pole at a velocity per in every 0.1 second speed in the eyepices view for 15-20 minutes and strangely eyepiece seeing was ok . Still the interior environs between splited rims were not seen sharply but outer black sharp shadows were well seen, so, shadow [A] consistently 1 hour viewed on the other hand shadow [B] was not viewed for 40 minutes and unexpectedly suddenly appeared as a 2km long, 200m wide jet black shadow in the x420 84 * bino- eyepieces view . This [A] and [B] consist the two legs of the rushing out blackbird shape black shadow that I observed in other nights 1.5years ago.
Turn my eyes to the 500-600km long west lunar limb of Mare Orientale environs for a brief rest, I could see some 10-15 single mountains and 5-6 twin mountains which looked almost similarly but with less details than that I posted here 6,21, 2014. , untill soon after dark clouds stopped the night,s observation.
In recent several lunar observing night, I thought about why there exist no atmosphere molecules on the Moon,… It,s because of weak gravity, .. then from where and when the gravity begins or generates ?
Myself final answer yet…. it generated from in the body of the every a quark or a lepton as a form of “graviton particles” . Need more study.
