This is an internal challenge the forum espacioprofundo.com.ar , astronomical section drawing, in which it was proposed to draw a globular cluster choice and these are the results. The credit of this picture is for Leandro Yasutake, Claudio Vidolini and Martin Boni, and we are representing espacioprofundo.com .
The three drawings were made in different parts of Argentina. The first (NGC 2808) was held in San Miguel, Buenos Aires. The second (NGC 362) in Malabrigo, Santa Fe; and the third (Omega Cen) in the town of Pergamino, Buenos Aires.

Equipment Used:

NGC 2808:
Telescope: Dobson 12 “.
Ocular: Plossl 10mm.

NGC 362:
Telescope: SW 305mm.
Ocular: Baader Hyperion 21mm.

Omega Cen:
Telescope: Helios 114/900.

Comet and Globular

Comet C/2014 Q2 (Lovejoy) and the globular star cluster M79 in the constellation Lepus

M79 and Comet Lovejoy in Lepus

I have been monitoring comet Lovejoy (C/2014 Q2) for the past several nights and on this occasion they both shared the same field of view at130 power. I was using my daughter’s 10 inch Orion Dobsonian telescope and was able to capture this sketch under clear skies and good seeing conditions. The observation site was in eastern Mesa, Arizona with a good view to the south. The comet can be seen much brighter and larger in angular size than than 8.5 magnitude globular cluster M 79. This was a pleasing view at the eyepiece with the comet showing a hint of green color. I switched to 48 power and a wider field of view for the sketch.

Sketching:

White and Black Conte’ pastel pencils on black sketching paper
blending stump and Pink Pearl eraser also used
R.A. 05hr 24′ ; Dec. -24 degrees 33min.
Comet distance less than 100million km.
M79 distance 42,100 light years 150 million stars

Conjunción del cometa Lovejoy con el cúmulo globular M79, en la constelación de la liebre.
El equipo con el cual se realizo la observación es un telescopio reflector sw 150/750 con un ocular de 25.
Podemos notar un bonito “triángulo ” entre el Cometa, m79 y la estrella HIP 25045 A. Se pudo observar un color con tintes verdosos hacia el centro del cometa. No se pudo observar coma

The region where the Great Nebula in Orion is accompanied by these two objects that sometimes is a little lost in the majesty of M42. in these drawings I wanted to highlight the stars reflecting part of the nebulosity of these young clusters

Globular Cluster Pair

A comparison between two globular clusters, M15 in Pegasus and M13 in Hercules - September 24, 2014 and September 27, 2014 — A comparison between two globular clusters, M15 in Pegasus and M13 in Hercules – September 24, 2014 and September 27, 2014

Hi,

Please accept my sketches of this beautiful pair of globular clusters, M15 in Pegasus and M13 in Hercules. Both globular clusters are spectacular objects by themselves but I thought it was interesting to pair them side-by-side to compare and contrast. M15 is smaller, has a more densely packed core and a more symmetrical shape M13 is larger, has a more loosely packed core and meandering streams of stars. The sketches were made on the nights of 9/24/2014 and 9/27/2014 respectively from a fellow club member’s observing field near Green Bay, WI using my 10” Discovery Dobsonian telescope at 120x. They were made using white paper with HB and 2B graphite pencils and blending stumps to smooth. Image colors were inverted using Paint.NET. I hope you enjoy it.

Object Name – M15 & M13
Object Type – Globular Cluster
Location – Near Green Bay, WI US
Dates – 9/24/2014 and 9/27/2014
Media – graphite pencil, blending stumps and white paper. Image colors inverted using Paint.net

Lost in the Small Magallanic Cloud

The Small Magellan Cloud, a dwarf irregular satellite galaxy of the Milky Way

Object Name: Small Magallanic Cloud
Object Type: Galaxy
Location: Argentina, Provincia de Buenos Aires, Monasterio
Date: 22/11/2014 Time 22:30 Hs
Media (graphite pencil, white paper, digital tools.
Telescopio: Reflector 130-900 Eq2 motorizado.
Eyepiece: BST 18MM (50X)
Seeing: 6/10.
En esta epoca del Año, las Pequeña nube de Magallanes, se encuentra a un elevacion 50º, permitiendo una observacion muy comoda. La idea de la observacion era registrar e identificar diferentes objetos de la Nube Menor asi como tambien de sus alrededores.
Dentro de la Galaxia pude observar 4 objetos:
NGC 330 : Cumulo Globular.
NGC 346: Region H II.
NGC 371: Cumulo Abierto con nebulosidad.
Estos 3 objetos ubicados en la parte inferior izquierda de abajo hacia arriba.
Por otra parte, en la parte centrar de la galaxia, pude detectar una region compuesta por un Cumulo Abierto con Nebulosidad denominado N19.
Lo interesante de esta region en el cielo es que es muy rica en objetos, muy cerca de la Pequeña Nube de Magallanes, se encuentran dos Cumulos Globulares, NGC 104 y NGC 362, estos dos objetos, fueron incluidos en el Skech a pesar de que no entran en el campo del eyepiece, pero realmente es una zona del cielo muy rica en objetos y no podia dejarlos fuera del skech

Traslator Google:
Telescope: Reflector Eq2 motorized 130-900.
Eyepiece: BST 18MM (50X)
Seeing: 6/10.
This time of year, the Small Magellanic Cloud, is an elevation 50 °, allowing a very comfortable observation. The idea was to record the observation and identify different objects in the Cloud Minor as well as its surroundings.
Inside the Galaxy could see four items:
NGC 330: Globular Cumulo.
NGC 346: H II Region.
NGC 371: Cumulo Open with nebulosity.
These three objects located in the lower left bottom upwards.
Moreover, in the part center of the galaxy, I could detect a region composed of an Open Cumulo with Nebulosity called N19.
The interesting thing about this region in heaven is that it is very rich in objects near the Small Magellanic Cloud, are two Clusters Globular, NGC 104 and NGC 362, these two items were included in the Skech though do not enter the field eyepiece, but it really is an area rich sky objects and could not leave them out of skech.

M29 The Cooling Tower and Surroundings
