NGC 7814 popularly and aptly know as the “little Sombrero” is a truly handsome classical edge on galaxy, resplendent with well defined dust lane and flying saucer outline. Getting such a large, and it was large completely spanning the filled of view and therefore completely spanning the monitor screen down on paper accurately is time consuming and I rarely render such splendour to my satisfaction, this instance proved to be no exception.

Object Type: Comet

Yesterday I observed the suddenly brightened comet 168P/Hergenrother. It now travels through the big Pegasus square and its magnitude is about m10.0 – easily visible in most backyard telescopes. I found the comet very quickly and at 50x my 280mm Dobson showed a littje fuzzy ball with a very faint tail. Higher magnification (150x) showed a bright, almost pinpoint nucleus and a wide tail stretching to the southeast. The best comet in years for me! The movement of the comet was so fast I could sketch it twice in the same starfield within one hour. At home I scanned the image and made an animated GIF to show the comet’s movement.
Unfortunately I can’t send animated GIFs via mail. To view the animation click: http://www.roelblog.nl/2012/10/komeet-in-uitbarsting-168phergenrother/

Object: Latysev 1 (possible moving cluster, Ari)
Date: 27. October 2006.
UT.: –
Equipment: 10×80 TZK binocular
Mag.: 10x
FOV: 6˚ x 6˚
Observer: János Gábor Kernya
Location: Astronomical Observatory, Baja, Hungary
Latysev 1:
„This is a possible moving cluster of only five stars, first suggested by Latyshev (1972). It was identified by considering the space motion of several nearby (GJ, or Gliese Catalogue) stars in this area. These 5 stars are spread over an area of 5˚ by 6˚, and are GJ 112 = HD 17190, GJ 113 = HD 17382, GJ 113.1 = VY Ari, GJ 118.2A = HD 18143 (one of three components), and GJ 120.2 = 51 Ari. The magnitude range is from V = 6.72 (51 Ari) to V = 7.81 (GJ 112), summing to V = 5.45 and B = 6.21.”
„It is interesting to note that three of these stars, GJ 112, GJ 113.1 and GJ 120.2, were also identified as members of a possible moving cluster “[AO84] III”, in a later study by Agekyan and Orlov [1984]. Therefore, if both of these groups are considered as real physical groups, Latyshev 1 should probably be considered a part of [AO84] III.”

Object Name NGC 4889 (=Caldwell 35) and vicinity
Object Type Galaxy (brightest in galaxy cluster)
Location Scheidegg, Bavaria, Germany
Date March 26th, 2012
Media Graphite pencil on white paper using blending stump, digitally inverted
NGC 4889 is the brightest galaxy in the Coma cluster. The view one gets in a larger telescope (I used an 18″ f/5 Dobsonian) is stunning. At least a dozen galaxies could be seen definitely, several more were assumed. The field almost showed as many galaxies as stars. NGC 4889 itself is pretty bright with a significantly brighter nucleus, slightly elongated in WNW-ESE. Sky conditions were good but not perfect, I logged a faintest star of fst 6m4 in Virgo. The magnification of the sketch is 94x. Beside the observation the identification of all seen galaxies was quite demanding. Hopefully, they are all correct.

Nome do objeto: M7/NGC6475 ou aglomerado de Ptolomeu;
Tipo de objeto: Aglomerado aberto
Local de observação: São Paulo, Brasil.
Data: 21 Julho de 2012, o2:05 UTC;
10° C, atmosfera calma, uma leve névoa.
Material utilizado: lápis Steadtler Mars Lumograph ( HB ao 8B ), papel Canson 200g/m2 cor creme, compasso, régua e esquadros.
Telescópio: Maksutov 90mm Skywatcher, ocular superploss 40mm ( 31,25x), diagonal dieletric Willian Optics , buscadora GSO 8×50.
Aproveitando o céu razoável, com uma tênue névoa.
O maksutov 90mm skywatcher ficou aclimatando por mais de uma hora e isso realmente dá diferença na observação.
O alvo desta madrugada foi outro agloemerado aberto do Escorpião e bem ao lado de M6 e das estrelas Shaula e Lesath.
A parte correspondente ao campo de visão da ocular teve as cores invertida no GIMP.
Object Name: M7/NGC6475 or cluster of Ptolemy;
Object type: open cluster
Local note: Sao Paulo, Brazil.
Date: July 21, 2012, o2: 05 UTC;
10 ° C, calm, a light mist.
Material used: pencil Steadtler Lumograph Mars (HB to 8B), Canson paper 200g/m2 cream, compass, ruler and squares.
Telescope: Skywatcher Maksutov 90mm, 40mm eyepiece superploss (31.25 x) dieletric William Optics diagonal, 8×50 finder GSO.
Taking the sky reasonable, with a faint mist.
The Maksutov 90mm skywatcher was acclimating for over an hour and this actually makes the difference in the observation.
The target this morning was another agloemerado open Scorpio and right next to M6 and stars Shaula and Lesath.
The part corresponding to the eyepiece field of view had inverted the colors in GIMP.
The southern lunar highlands expose the ancient anorthositic crust between craters. Centered in this southern highland sketch is the buried pre-Imbrian crater Heraclitus (92 km.) with its unusual central mountain crest. This ridge or crest looks much like the one on the floor of the elongated crater Schiller formed during its shallow angle impact. The ends of Heraclitus are buried under Licetus (77 km.) to the north and Heraclitus D (52 km.) to the south. Its easy to imagine this possible Schiller twin here partly hidden. To the east is crater Cuvier (76 km.) with its smooth floor and western wall pressing in on Heraclitus.

M7 – Open Cluster
Warren County NJ, USA

Sketched on a laptop computer
M7 is a beautiful open cluster in the constellation of Scorpius. With a magnitude of 3.3 it is visible to the naked eye and is very impressive in binoculars and wide field telescopes. The sketch was done while at the scope on a laptop computer.
I send you the historic comet P/ Giacobini-Zinner (period: 6.6 years) from my observation
in aug, 1985. (info on my sketch).
This comet with the thin tail is the parent body of the Draconid-meteorshower which
had a major outburst 9. oct. 1985.
On that date my friend and I observed and photographed comet Halley while a rain of
meteors crossed the sky from the radiant in Draco. (I found Halley the day before).
I was happy to have seen and observed the parent body G-Z about two months earlier!
I used watercolorcrayons on black paper.
Location: Trondheim, Norway.
Best wishes from Per-Jonny Bremseth.
