Trying something New with the Sun

The H-alpha Sun - May 9, 2014 — The H-alpha Sun – May 9, 2014

Aloha!

I was enjoying the Sun this morning and trying to decide how to represent the most prominent features. Sketching the Sun has just not gotten me the feeling that I can really represent it as well as I would like to as far as colorizing goes. I like using black paper but it isn’t smooth enough whereas plain white paper is. But when I have tried to add color later, it just loses what I see in the scope.

So today I tried a little something different. I like how some inverted blue colors really become the right colors for the Sun. So I put some oil pastel colors to paper & inverted to see what I could use. The nice thing about the oil pastel is I can scratch off small little lines to try to get the details of the solar surface. I had to think in negative to produce the sketch in order to preserve black, white and the different tones of red. This is my 1st attempt using this technique and I am not entirely happy with it but it is a bit of an experiment.

Mars Observation (April 29, 2014)

Mars - April 29, 2014 — Mars – April 29, 2014

Mars feature location and nomenclature chart - April 29, 2014 — Mars feature location and nomenclature chart – April 29, 2014

I made an observation of Mars on April 29, 2014 (03:30 U.T. or 11:30 PM EDT) using a 9-inch (23-cm) F/13.5 Maksutov-Cassegrain at 258x and 310x. Syrtis Major was prominent preceding the central Meridian (CM) with a cloud noted over its midsection flowing towards the East and into Libya (extending from an Equatorial Cloud Band (ECB) extending from from the following limb). The Hellas basin was noted to be very bright south of Syrtis Major towards the southern limb. Sinus Sabaeus was visible as a dark extension from the CM towards the South-following limb. The North Polar Cap (NPC) appeared small and brilliant. The NPC was surrounded by a dark collar. Dark to dusky maria was noted over the northern hemisphere of Mars. I have included an image that is labeled with the nomenclature of the majority of albedo features noted.I hope that you all like it.

Regards,
Carlos

Mars April 20, 2014

Hello, here is a picture of Mars made with my Dobsonian Telescope 12 “equipped with a binocular , with a magnification of 500x. Viewing conditions were really excellent, which was rare in early spring … Many details were visible, including the famous Syrtis Major and Sinus Sabaeus visible right training up. I also observed a beautiful cloud formation on Elysium, left visible at sunset

Mars April 19 2014

Conditions were poor to average for viewing and sketching Mars. Mars is now at 15″ of arc and 0.62 A.U. from us. 99.4% of the disk is illuminated and shining at visual magnitude -1.4. The central meridian of Mars was centered at about 41.87° at the beginning time of the sketch.

Sinus Meridiani was visible near the limb on the preceding side. On this side clouds were visible over Eden. Mare Erythraeum, Margaritifer sinus and Aurorae sinus were all detectable to the south (up). Lighter Chryse could be seen at the equator with Niliacus Lacus, Mare Acidalium and Nilokeras blended together. Tharsis was under clouds on the following limb. The north polar cap is small in size and set apart by Mare Boreum.

Equipment and Sketching:

This is an eyepiece sketch made with a HB graphite pencil, blending stumps, White Pearl eraser on white sketching paper. The colorized sketch made indoors was completed using ground shavings of colored pencils (blue, orange, yellow, white)

Telescope: 13.1 inch f/5.9 Dobsonian and 9mm eyepiece 218x with a single polarizing filter and Neodymium filter used together; An Equatorial platform was also used

Lunar Hide and Seek – Occultation and Lunar Eclipse

The Lunar Eclipse and occultation of April 15, 2014

Aloha!

Tonight after setting up with friends and being thwarted by clouds, I raced home to see if I could still observe part of the lunar eclipse from a different location. Upon arriving home I found it was clear and quickly set up my 15×70 binoculars. I was delighted to see h Virginis just peeking its bright head out from behind the limb of the Moon and quickly started a sketch of my observation. The umbra had almost made it over the last portion of the limb and the remaining edge was brightly lit. The Moon took on a coppery glow and the stars shone nearby that normally cant be observed during full Moon.

Bonjour,
Un dessin de M42 réalisé sur 2 nuits (7h d’observation) au T400 en Nouvelle Calédonie. Tous les grossissements ont été utilisés, mais principalement 300x. Ciel perfectible avec des passages nuageux génants.
C’est un dessin original format A4, en négatif couleur sur un champ préétoilé, colorisé L, V(OIII), R(H-béta) , reprise des étoiles sous photoshop.

J’en profite pour rappeler la sortie de notre ouvrage commun
“ASTRODESSIN, Observation & dessins en astronomie”
http://www.astrodessin.com/

Hello,
A drawing of M42 performed on two nights (7am observation) at T400 in New Caledonia. All magnifications were used, but mainly 300x. Perfectible troublesome sky with clouds.
This is an original drawing A4 format color negative on a préétoilé field colorized L, V (OIII), R (H-beta), resumption of stars in photoshop.

I want to remind the release of our joint work

The Cat’s Paw

NGC 6334 (Cat's Paw Nebula) — NGC 6334 (Cat’s Paw Nebula)

Bonjour

pour l’ASOD, je te propose la nébuleuse de “la patte de chat” NGC6334 observée en août 2013 au Chili, désert de l’Atacama au pied du VLT, avec le T400 de voyage en carbone (15kg), ethos 8 et 13mm.
Quasi inexistante sans artifice, elle se révèle sans pareil avec un H-béta, d’où cette idée d’une colorisation L, Rouge (H-béta), Vert (OIII).

The Charm of ISON

C/2012 S1 (ISON) - November 16, 2013 — C/2012 S1 (ISON) – November 16, 2013

Hello ! Here is a drawing Ison (only unfortunately) made Friday morning between 6:15 ET 6:45 HL with my newton telescope 12″. Visible with binoculars 8×40, Ison revealed all its charm to the telescope, including its beautiful clear blue hair, as well as two fine jets in the queue that stretched over 3/4 of my ES 20mm, which provides a field of 1.36 ° and a magnification of 75x.
A real treat for the eyes! Strongly in December…

I’ve really been enjoying the current set of active regions the past few days. It would be nice to sketch each individual active region as a close up view, but to do that would take several hours. As it was today, I struggled with a group of thick clouds for the first hour of my session. The sky was crystal clear when I set up and I chose to ignore the weather channel for my area stating that we could have thunderstorms at 8 a.m. Thankfully the storms never came…the clouds did. I was able to catch glimpses of the Sun in between the clouds and by 8:45 a.m., the sky was nearly unobstructed.

The first features added to the sketch after the prominences were plage from 1476 and 1471. Next came the sunspots themselves and filamentary structure. By 9:10 a.m. (1410 UT), very bright plage appeared just north of the sunspots in 1471. I haven’t been able to confirm yet if it was a solar flare, having expected possible flare activity in 1476 instead. But it lasted nearly an hour before it dulled somewhat. Near the end of my session, 1471’s plage brightened quite a bit to the eastern side of the major sunspot in that region as well as about five more degrees further east again.

1474 and 1475 paled in comparison to the two major active regions. There were nice filaments and thin plage that made them easy to find.

The large chain of filament reaching to the southern limb was still there, although thinner. Prominences scattered around the limb were insignificant.
