Bullialdus Crater - 29 January 2015 — Bullialdus Crater – 29 January 2015

Object Name: Bullialdus cráter and company
Object Type: Lunar crater
Location : Granadero Baigorria, Santa Fe, Argentina
Date 29 – 01 – 15
Media: Pencil HB, 2B , 4B , Blending stump, white paper and Software Paint.NET to invert colours and minor details

This crater is located in the western part of Nibium Sea. It has a dimension of approximately 60 x 60 km . It is accompanied by Bullialdus A and Bullialdus B, two craters considerably smaller.Like the idea was to draw the area , you can see the KONIG crater (20 x 20 km), which is a little more to the west, and LUBINETZKY crater . The observation was made with NW telescope Sky watcher 150/750, with a TMB II 5 eyepiece

Western Highland Peninsula Craters

For those that observe and sketch the Moon, trying to pick targets just before, just at and just after first quarter can be much fun because there are so many choices in good relief. On this occasion I chose two large walled plain craters near the terminator. Albategnius (129 km.) the younger of the two ancient craters and further from the terminator it was displaying its central peak (1.5km. tall) and large crater Klein (44 km.) on its rim. Crater Halley (36 km.) to the northeast is notably a kilometer deeper than Klein and although further from the terminator has a completely shadowed floor with that greater depth.

The other large crater Ptolemaeus (154km.) was on the terminator at the beginning of my sketch.
With the sun so low the rim shadows were long and were creating a special effect. In combination with the rim shadow of little crater Ammonius (8.5 km.) I could see old Nesse. Jim Adlhoch describes the floor shadow as looking like the head and neck of the Loch Ness monster- see Lunar Photo of the Day September 4, 2014.

Crater Ptolemaeus has a floor covered with many shallow bowl shaped craters, ghosts buried under lava. These ghost craters can be seen at low sun but the central peak is completely absent. To the north is crater Herschel (41 km.) with a shadowed floor.

Belleza en la Simplicidad

It’s a triple sketch, staring Minkar, Regulus and Mimosa (from left to right), all of them stars.

Location: La Matanza, Buenos Aires, Argentina.
Date: 02/03/2015
Media: Graphite pencil, white paper, Photoshop.

Seeing didn’t help at all, but anyway, it took me a while to finish the sketchs; the original idea was to draw at least six different stars from different constellations, but right after finishing Regulus, clouds came out to stop my work.

As a result, these are the three sketched stars. Hope you enjoy it!

Jupiter triple shadow transit – 24 January 2015

Object Name: Jupiter
Object Type: Planet
Location: Stokesley, North Yorkshire, UK
Date: 24th January 2015
Media: HB, B, 4B pencils, blending stumps, kneadable eraser on white paper

I used a 130mm reflector at 100x to make this sketch. The weather was cold and clear with good seeing and a limiting magnitude of 5.4. Despite the good seeing, I had to be quite patient to see all the shadows. Callisto itself was easy but Io was quite difficult. It was wonderful to see the shadows suddenly appear during moments of good seeing but at other times not all of them were visible at any one time.

Open Cluster NCG 2477

Object Name: NGC 2477.
Object Type: Open Cluster.

Date: 18/02/15.
Media: 2B, 2H, HB, blend and PS.
Telescope: Meade LB 12″ on equatorial tracking platform.
Eyepiece: BST Explorer 18mm (x84) .

One of the best open clusters of the sky and my all time favorite!

The Horsehead Area with a RFT

Object name: IC434, B33, Horsehead Nebula
Object type: dark nebula
Location: Cottage Grove Lake, Oregon
Date: Feb 21, 2015
Media: charcoal and graphite pencils on drawing paper, scanned to jpg

C / 2014 Q2 (Lovejoy) – Beautiful Comet!

C / 2014 Q2 (Lovejoy) - 13 February 2015 — C / 2014 Q2 (Lovejoy) – 13 February 2015

Object Name: C / 2014 Q2 Lovejoy- beautiful comet!
Object Type (comet)
Location (Oborniki, Poland)
Date (13-feb-2015)
Equipment: binoculars Vixen 16×80
Object: – Artist: Robert Twarogal (Ignisdei)

There was suburban, slightly hazy sky, although it was clear enough, stabilized by frosty atmosphere.

Beautiful and bright comet reigned today on the border of Perseus and Andromeda near the star Alamah. It was a really marvelous, faint shield, perfectly visible in the wide field of binoculars Vixen 16×80. Also appeared quite delicate colour (as in the planetary nebula) such as glimmer of green. The comet looked like a miniature of asterism swan constellation. 4 star: In the left yellowish HD 1152, in the middle blue-and-white Hd 11188, and on the right white HR 526

The comet core flowed through the center of Hd 11188 star. At the bottom of asterism was like miniature Albireo – yellow SAO 37533,

My Vixen showed also almost visible beam which climbed up. This jet (tail of the comet) was extremely faint and diffuse, shooting up like a geyser!

I encourage you to observe C / 2014 Q2 Lovejoy-beautiful comet!

Yours Robert

Conjunction Venus, Mars and Moon

Object Name: Venus, Mars and moon
Object Type: Conjunction
Location: Mystków, Poland
Date 20.02.2015, ~17:00 UT
Media: graphite pencil, white paper, PhotoFiltre 7

Hello everyone.
This is my latest sketch conjunction of Venus and Mars. The planet was near the moon, one day after the new moon. You can see the moon was light gray. When sketching, the sky was clear, visibility was very good, light wind was blowing.

Lovejoy / M76 Rendez-vous.

M76 and C/2014 Q2 (Lovejoy) - 19 February 2015 — M76 and C/2014 Q2 (Lovejoy) – 19 February 2015

Object Name (M76 & C2014/Q2 Lovejoy)
Object Type (Planetary nebulae and Comet)
Location (Observatoire Astronomique de Bauduen – Verdon – France)
Date (2015-02-19 / 21:00LT)
Media (graphite pencil, on white paper, paint.net and MS Gif animator)

Once again I had the opportunity to use the fast (3.3) 24″ reflector made by Olivier Planchon. The EP used is a 2″, 31mm Nagler.
The C2014/Q2 Lovejoy comet fades out on its way back. In the same FOV we can see M76 a planetary nebulae. The NGC number is double because when discovered people suspected that this was a double nebulae (NGC 650 & NGC 651). The distance of M76 is still unknown.
During our 1 hour session we were able to observe the displacement of the proto-nucleus facing a nice m= 8.7 K5 red star, SAO 22504. The separation was here only 1’. To make this small gif animation I made 7 sketches to indicate the relative positions.
The light of this star takes 1400 years through the coma to reach our planet while the light takes only 10 minutes from Lovejoy to us.
That was a nice double rendez-vous!

Clear sky to you all!

Little Girl’s Lovejoy Sketch from Memory

Róisín Mulligan is only nine , she had a look at C/2014 Q2 Lovejoy in my telescope for what was really a brief encounter. Like the other children in the club she was queuing up to see their first ever comet. Somehow unknown to me she managed to produce a sketch in the dark in her own notebook , directly from her memory . This sketch surfaced when we returned to the classroom to finish up our meeting. What a great independant effort on her part , everyone was impressed.

Viewed in a 200mm dob, 32 mm eyepiece ( 37X) with a 46 % illuminated moon in the way ! Róisín attends St Patricks National School Bray ,Co Wickow Ireland and is also a member of St Cronans Stargazers Astronomy Club at St Cronans National School in Bray.
Well done Roisin, great work !!
