H-Alpha Sun - June 29, 2012

Object Name: Sun
Object Type : Full disk
Location: Montreal, Canada
Date: June 29th 2012
Media: Red pastel on black paper, Photoshop CS3

This is my first sketch of the sun in H-alpha using my new solar scope Lunt LS60THa. The Lunt Zoom eyepiece, 7.2 – 21.5 mm, was used. Seeing was 3/5.

Saturn, Titan and Raindrops

Object Name: Saturn
Object Type: Planet
Location: Deventer, The Netherlands
Date: May 13, 2012
Media: Pastel pencils on black paper

Last night I wanted to make a sketch of Saturn, mostly to capture as much moons as possible through my old 75mm f/15 Polarex/Unitron refractor. After 45 minutes of sketching at 200x with pastel pencils on black paper, Saturn was pretty much done (although I found it surprisingly difficult to draw a good ellipse for the rings), and just when I added the easily visble Titan, I heard some droplets on the trees next to me and felt something on my head: RAIN! I immediately covered the pastel sketch witch my hand and rushed inside my shed. After the sketch was save I pulled the telescope out of the rain. The most abrupt ending of a sketching session ever! I had completely missed the incoming clouds while viewing through the eyepiece.

Anyway, both the sketch and the telescope survived. Sadly with only one moon observed: Titan.

Clear skies and kind regards,

Total Eclipse of the Moon – December 10, 2011

Lunar Eclipse - December 10, 2011
Lunar Eclipse - December 10, 2011

After careful plans to observe the total lunar Eclipse of Dec 10th 2011 in the Portland city center, fog formed late, so plans to relocate were rushed at the last minutes as we drove fast from the city to the Columbia River Gorge Crown Point Oregon Vista House, yet only to find a hundred people, photographers, etc, most were ensconced in their cars with engines running, while Gorge east winds gusted to 60 mph with 25 degrees F.

So I set up my Celestron Nexstar 5i telescope anyway, huddled into the wind-shielded side of the Vista House with a few brave other photographers. I made quick mental notes of the image at medium power through the telescope and began to photograph crudely as the wind buffeted the scope and my Sony NEX5 camera poised high and teetering on its tripod over the telescope eyepiece. It was difficult at times as I began to speak as my hands froze and unable to operate the telescope or the camera, worse, many people approached then asking me if I could tell them what was happening as I appeared as the only professional with serious equipment in the grueling wind and freezing temperatures. They heard in the media and then recalled all the hoaxes of misunderstanding of the moons image as a rare visible sight setting in the west while the sun rose in the east. I had to explain the atmospheric effects of light bending through a natural lens. It was fun and although the constant fumes of diesel engines running for those who would not disembark from their warm cars, a few of us weathered the bitter cold, ironically lady friends of mine stayed until sunrise, where my professional photographer friend dressed in Alaskan outback parka and full proper clothing, refused to get out of the car.

Much in post preparation was then later made in the past week at home to produce this accurate large technical documentary dry pastel sketch onto 19″ X 25″ black Strathmore pastel paper completed today, December 19th 2011. It comprises a time span of possibly an hour as the moon was also observed at speed in my Mercedes side view mirror as I drove out the I-84 highway at super-legal speeds, the earths red shadow on the moon changed fast. So the sketch is possibly at just before full totality. Then daylight began to creep up in the east just as I arrived and set up the telescope [as depicted in the reflection of the old historic gas street lamps at Crown Point. Portland’s city lights 30 miles to the west are seen under a shroud of fog. This is also rendered in the sketch and as a final artist’s conception, the still deeper reflection of the moon as an image seen in a mirror within a mirror, on the Vista House windows.

Two Days of Incredible Solar Activity

H-Alpha Sun - November 12 and 14, 2011
H-Alpha Sun - November 12 and 14, 2011

Object type – Huge filament and prominence
Location – Wilp, The Netherlands
Date – November 12 and November 14, 2011
Media – Pastel pencil on black paper, color with Photoshop

The largest prominence and the largest filament I have ever seen, both visible at the same time! It was a fantastic view and I made two sketches of them, two days apart. On November 14, the huge filament blew a large part of itself away from the Sun at the exact moment I was observing, creating a thin candle-like flame above the surface. A remarkable sight. Clearly the Sun is getting more active every month. What it’s got left in its suprise box while creeping towards solar maximum? Can’t wait to find out!

Jupiter and the Moon in Conjunction with the big Tower

Object Type: Conjunction
Location: Montreal, Canada
Date: October 13th 2011
Media: Pastel
On October the 13th while returning home after a lecture given by the astrophysicist J.P. Luminet, I saw this beautiful conjunction between our moon, Jupiter and the Dome of the Tower of the University of Montreal where I work. Our moon looked as if it rested on a small cloud. I sat on a nearby bench and took my time to sketched the view in my notebook. I copied the sketched at home on black paper, adding colors with pastel.

Full Disk Feast

H-Alpha Sun - August 2, 2011
H-Alpha Sun - August 2, 2011

This morning everything seemed to be right. The weather was absolutely great, the Sun was more active than I’ve seen so far this year and the seeing was above average. A good day to try sketching a full-disk h-alpha sun for the first time instead of an isolated prominence. First I made a blank disk with a soft white pastel. I took the sketch outside and filled in all the details I could see through the eyepiece of my 70mm solar telescope with white and black pastel pencils. All regions were very active, especially the middle one: it changed its shape within minutes. Sometimes little bright flare-like brightenings appeared and disappeared 2 minutes later. A wonderful sight! It took me one hour (from 08.00 UT – 09.00 UT) to complete the drawing. I scanned the (black&white) sketch and gave it a reddish color with Photoshop.

The Reason for the Messier Marathon

April 2 to 3 participated in the Messier Marathon without a star chart.
The weather is not good all night, but one hour before twilight sky cleared.
While frantically looking for the star, suddenly the day was bright…

What is the reason for the Messier Marathon?
Just before twilight of breathtaking suspense.
Maybe it’s the reason for the Marathon.
