The double cluster in Perseus

NGC 884 & NGC 889
NGC 884 & NGC 889

Hola!

The double cluster in Perseus has always been a challenge for me. But when I came across an impressive dark sky, I did my best and this is the result.

I hope you like it.

Lunar Crater Gassendi

Crater Gassendi - 31 January 2015
Crater Gassendi – 31 January 2015

Hi all,

tonight I had a look outside and – yeah, no clouds and clear skies.

So I took out the 10″ f/5 truss dobsonian and prepared for lunar sketching: Today the floor-fractured crater Gassendi attracted me and presented nice central peaks and its rimae on its ground.

Telescope: 10″ f/5 Martini Dobsonian

Eyepiece: Skywatcher Planetary 5mm

Date & Time: Jan 31st, 2015 / 1925-2015 CET

Place: home terrace, Dusseldorf region, Germany

Technique: chalk, charcoal and white pastel on black sketching cardbox paper

Hope you like the sketch.

Clear skies!

Venus-Uranus-Mars—Two Conjunctions

Conjunctions of Venus, Mars and Uranus - 11 March 2015
Conjunctions of Venus, Mars and Uranus – 11 March 2015

Object Name (Venus, Mars, Uranus)
Object Type (Planet conjunctions)
Location (Artignosc-sur-Verdon – Provence, France)
Date (11/03/2015)
Media (graphite pencil, watercolour pencils, white watercolour paper, Paint.net)

I always have issue to find Uranus, without GoTo, it’s not so easy…and I don’t like facility…
Thinks are moving in our planet system. It’s why “planetos” in Greek means “vagabond”.
So I use the opportunity of this double conjunction just a week from each other to find Uranus and its so nice colour.
The Venus-Uranus separation was 5.2’ Venus was 10’000 more brilliant than Uranus, while the separation between Mars and Uranus, one week later was 16.25’
The faint K star between Mars and Uranus is HIP 4325 mag=9.5, so no Uranus satellites were visible with my material.

I sketch the two fields on white watercolour paper with inverted method using a chromatic wheel, orange for Venus, blue for Mars and crimson red for Uranus then I just have to invert the two sketches after scanning. The deal is to manage the colour values in inverted mode.

Clear sky to you all, and for some of you I wish you a nice eclipse on Mart 20.

El Joyero Bajo la Luna

Este es el segundo dibujo que hago de este cúmulo abierto. Decidí volver a retratarlo bajo condiciones distintas de observación, esta vez había Luna llena y la idea es comparar ambas condiciones de observación. El seeing no era muy bueno, la atmósfera presentaba turbulencias que desenfocaban la imagen por momentos.

El dibujo fue realizado con papel y lápiz, posteriormente procesado en Photoshop para invertir los colores y simular el efecto de resplandor que genera la luna en el cielo. Además agregué algo de color a las estrellas, tal como las veo a través del ocular (huygens 25mm), pero los colores se atenuaron un poco al fusionar una capa celeste para dar el tono de luz de Luna al fondo. En realidad deberían verse los azules y el rojo de la estrella central más vivos. El equipo que utilicé para realizar el sketch es un telescopio reflector marca Helios, de 114mm de apertura y 900mm de distancia focal. El dibujo fue realizado desde Pergamino, Buenos Aires.

This is the second drawing I do this open cluster. I decided to portray under different viewing conditions, this time there was full moon and the idea is to compare both conditions of observation. The seeing was not very good, the atmosphere had desenfocaban image turbulence at times.

The drawing was done with paper and pencil, then processed in Photoshop to invert the colors and simulate the glow effect generated by the moon in the sky. Also I added some color to the stars, as I see through the eyepiece (huygens 25mm), but the colors are dimmed a little by fusing a celestial layer to set the tone of moonlight in the background. Actually should be blue and red brighter central star. The team I used to do the sketch is a reflector telescope Helios brand, 114mm aperture and 900mm focal length. The drawing was made from Parchment, Buenos Aires.

Flaming Star Nebula

Aloha,

IC 405, Caldwell 31 or the Flaming Star Nebula is an emission/reflection nebula that requires darkness and patience to pull details out. A 12.5” reflector was used here to observe and a NPB filter from DMG optics helpful. I observed & sketched the same object 3 years ago and didn’t see the details visible this time around. I would partly account this to gaining greater ability from sketching the object again with more patience this time around.

Proper motion studies of AE Auriga show it to be an ejected star from the Orion Belt region. Its chance passage through this nebulous region of gas & dust give it a “Flaming Star” appearance.

Jupiter – Io covered Europa

Jupiter and Moons - 26 February 2015
Jupiter and Moons – 26 February 2015

Last week at the 26th. February I took the chance to make a sketch of the mutual moon cover. Of course, I also observed Jupiter. The air was not so good but in quite moments there were some details to hold.
All in all it was a real fantastic night. First ran Callisto and its shadow over the planet. Then Kallisto covered Europa and at last moved Io over the planetary disk followed by his shadow.

I enjoyed the Moment when Io covered Europe and sketched this nice scenery for my astro-log.
