The Great Elongation of Mercury - May and June 2014

The Great Elongation of Mercury – May and June 2014

In the spring of 2014 we observed a super elongation of Mercury; high brightness and large apparent diameter.
I followed up the Mercury from 9. May to the fifth day of June. I got a great experience and a wealth of experience.
I managed to identify a lot of formation on the surface of Mercury, despite I used a small telescope. I hope you enjoy this little compilation! :-)

M22 – the quietly spoken big brother globular cluster

Wed, 09/10/2014 - 03:00
Messier 22, the great globular cluster in Sagittarius

Messier 22, the great globular cluster in Sagittarius

Hi all,
This was the second sketch I completed at this year’s Astrofest back in July.

M22 is a true jewel of the night sky. This giant globular cluster from a dark site it can be a naked eye object as well. It is large enough for even smaller telescopes to resolve its multitude of component stars, revealing its large and intense core.

M22 is beautiful in my 17.5” scope. It is very different from Omega Centauri and 47Tuc – could even describe it as the ‘runt’ of the giant globulars as its core is not as busy as its bigger brothers. But the component stars of its core are absolutely brilliant, arranged in so many signature patterns. It is slowly turning into a favourite of mine with its understated brilliance, loud without being overbearing presence, and sitting on a magnificent carpet of the Milky Way glow.

I won’t say much here. I’ll let M22 do its own quite whispering of its magnificence. Yeah, I think one firm fav of mine now…

Alex.

Crater Clavius Out and Over the Terminator

Sun, 09/07/2014 - 03:00
Lunar crater Clavius - September 3, 2014

Lunar crater Clavius – September 3, 2014

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.

Comet Jacques & Struve 3053

Comet  C/2014 E2 (Jacques) in conjunction with Struve 3053  - August 24, 2014

Comet C/2014 E2 (Jacques) in conjunction with Struve 3053 – August 24, 2014

I found this comet in Cassiopeia the other night (August 24) near the colourful double star Struve 3053 and thought it made a nice composition. As I observed over the course of an hour I was surprised to see how quickly the comet moved against the background stars from the position I first sketched it at 11:15 local time to the position indicated by the X at about 12:10. The observations were made with a 120mm F/8.3 refractor at 42x in a 68 degree eyepiece from my Orleans, Ontario backyard.


Running Jacques !!!

Comet C/2014 E2 Jacques -  August 27, 2014

Comet C/2014 E2 Jacques – August 27, 2014

* Object Name: C/2014 E2 (Jacques)
* Object Type: comet
* Location: Castres (Tarn – France) N43.35 E2.14
* Date: August 27th 2014 21h35 to 22h55 UT
* Media: pencil HB + 2B, white drawing paper, scanned + inverted & colorized with PhotoPaint

Conditions: humidity 80%, 18°C, no wind.
Excellent transparency and pretty good seing
No Moon
Equipment:
– Dobson Orion XT12 (300 x 1500mm => F/D 5)
– Eyepiece Televue Panoptic 15mm (mag x 100)
– no filter

While watching at this nice comet, close to Cephei, I got stunned seing the velociy of this object.
After only 5 minutes, I could notice a change in it’s location at only x100 magnification.
So I decided to take my scratchbook to report its moving path during a couple of hours.

There was no visible tail, I just could detect a slight dissimetry on the coma.
I was stargazing in (small) town, in my garden, with some lights around, so this was not the best condition.
The nucleus is not so bright as last Lovejoy’s one, and the green colour is fainter than the representation I made (just a little cheat:)
The magnitude is difficult to estimate on these objects, but I guess it was about 7 or better.

The comet was on Aug. 27th the closest from earth (about 0,56UA) and it is also reaching these days it’s peak of activity.

NOTE : On Aug 31th 0:00 to 2:00 don’t miss the conjunction with Mu Cephei (the beautiful Herschel’s Garnet Star) even maybe an occultation by the comet!

Thanks for your interest.

Webmaster’s note: ASOD viewers have probably noticed that Comet Jacques has been the focus of the last few days. This reflects the great number of excellent sketches submitted of this comet.


4 Dimensions for Jacques

C/2014 E2 Jacques - August 24, 2014

C/2014 E2 Jacques – August 24, 2014

Object Name (C/2014 E2 Jacques)
Object Type (Comet)
Location (Varages Provence France)
Date (24-08-2014)
Media (watercolour, 4 white paper, Paint.net and 3D photo maker)
With our sketches we are staying with 2D only, the two dimensions of our papers.
So, I project to reach 3D with anaglyph (cyan-red) glasses. It’s not so easy to make four watercolour layers, two inverted one naked eye for the sky and another through the eyepiece for the comet, plus two classical views one for the telescope and one for the landscape… and then compile all of them with stereo slip.

But on top of that I want to reach another dimension, the time! Today, it was the good time to try that!
This Lautter refractor, was build in 1830 ! The telescope and this lovely mount aren’t copies but originals. In the year 1830, the comet Jacques was very far from the today’s orbit. To give an idea of this 1830 old-time, we just invent photography and railway, the country of Belgium, the cities of Miami and Victoria doesn’t exist yet. That gives us an idea of the fourth dimension.
The light coming from the comet Jacques was seen trough those very old lenses.
The watercolours show this old lady refractor of Jean-Luc and Caroline, my friends from the “La Blaque” domain, near Varages in Provence.
This antiquity was shown for the first time to the public during our yearly star party : august 2014 24th; what a success! I was lucky to receive some EP time (just 15 minutes) to sketch the comet Jacques. Regarding the long queue of curious waiting for a view of the comet I was quite happy.
A diameter of 180mm f/d 15 with a 40mm eyepiece gives a magnification of 67X. The end time for the comet field was 21:45 UTC.

To see the 3D effect of the second picture you have to use anaglyph glasses.

Clear sky to you all !

Zeno Crater

Tue, 08/26/2014 - 03:00
Zeno crater - August 11, 2014

Zeno crater – August 11, 2014

Zeno crater imagined- oil painting

Zeno crater imagined – oil painting

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.

The Sagittarius Stellar Cloud

Mon, 08/25/2014 - 03:00
The Sagittarius Star Cloud, Messier 24

The Sagittarius Star Cloud, Messier 24 and Messier 18

The Sagittarius stellar cloud, also known as M24, is one of the most dense patches of the Milky Way. It’s 600 lightyears across and some of the stars you can perceive through a decent pair of binoculars lie more than 10.000 lightyears deep into our galaxy, straight towards its core. It would have been impossible to draw all individual stars. Not just because there were so many that they rather appeared like a genuine cloud across my field of view but also because they were so faint that you’d constantly wonder whether you’d seen an individual star or not. A nice detail is the pretty little cluster M18 by the top border of the field of view, another one of these “jewel boxes” in the sky.

I made this sketch in my backyard in the Italian mountains with my Nexus 100 binoculars and a pair of Siebert 21mm Ultrawide eyepieces (24x). Pencil on white paper and then processed in Photoshop.

Cheers!
