Hi Asod! My sketch is about a triple and a double stars, in the same field. The triple is STRUVE 2816 and the double STRUVE 2819 and they are both part of the wide open cluster “Trumpler 37″ in Cepheus. I observed the two multiple systems with my Dobson 10” f/5 with a 14mm eyepiece, 82° for a 180x magnification. The observation is great!

Hi everyone,
In a slighly cloudy evening on 18th September, searching holes through the clouds, I have been able to observe one of most famous double star Albireo or beta Cygni. The seeing was very good and giving me a stationary image.
I have wanted o make a sketch of this spectacular object and its amazing colour contrast.
I hope you like it.
Bye.

NGC6309 – Exclamation Mark Nebula

Object Type: Planetary Nebula

Location: Tarragona – Spain

NGC6309 is one of the two planetary nebula with the nickname “The Box”, (the other is NGC6445 in Sagittarius), but after my experience with it, I prefer name NGC6309 like Stephen J. O’Meara in his book “The secret Deep”: The Exclamation Mark.

Hi Asod! Last night I observed Beta Monocerotis, which is called the most beautiful multiple star of our skies. I also loved it, so I decided to sketch the star with my dobsonian telescope 10” f/5. Seeing was not bad, so with 250x I could note easily all the components; but colours were not simple to note, all of them seem to me white, bluish and greenish…
Wonderful star!

Moon Race Watercolour

July 4-8, 2014 - Conjunction of the Moon, Mars, Saturn and Spica
July 4-8, 2014 – Conjunction of the Moon, Mars, Saturn and Spica

* Object Name (Moon, Mars, Saturn)
* Object Type (Conjunctions)
* Location (Artignosc-sur-Verdon – Provence – France)
* Date (2014 from 4 to 8 July)
* Media (Watercolour, white paper, paint.net to invert the result)

From July 4 to 8 Moon played with planets. From a purely astronomical point of view the Moon showed us some beautiful conjunctions, Mars, Spica and then Saturn. By the way the game was a little complicated with the clouds. What a season!
On July 5, the moon was still visible behind heavy clouds. The next day, I have not even been able to detect the moon light ! I had to invent the sky. July 7, when the Moon approaches Saturn, clouds returned to disturb the magic of the moment. I’m a bit fed-up about this weather, and I think not being alone!
The advantage of astro-artist on the astro-photographer is that we can complete our design. This time I have to add the missing lunar position on the view. And to capture those irritating clouds, I painted a hazy wash around the Moon as was the case on July 5.
The small hilltop village that served as a foreground is called Artignosc-sur-Verdon. I confess to being quite happy by this view. Artignosc is just halfway to two now well-known astro-spots “The Blaque” in Varages and the OAB in Bauduen. And ‘cause we are nevertheless in Provence, believe me above the clouds the sky is very dark!
Still … what a season!

To do this watercolour, I went out on my terrace at ten PM every night, sometimes before the storm, sometimes after and once during, being passionate or you do not. Every time I sketched some sketches in a hurry, and took two or three pictures allow me to keep the shades. At the workshop, I started by gathering the different positions of the stars and their locations relative to the village. In less than a week, only the Lunar race was noteworthy, Mars and Saturn are much quieter than the stars. Then I realized in reverse mode (colors and contrast) this watercolour. I just had to scan my sheet and reverse the colors.

A Tail of Two Comets and Algol

Comet C/1996 B2 (Hyakutake) - April 10, 1996 and Comet C/1995 01 (Hale-Bopp) - April 10, 1997
Comet C/1996 B2 (Hyakutake) – April 10, 1996 and Comet C/1995 01 (Hale-Bopp) – April 10, 1997

Hey ASOD!

This is not often to see on the sky, two comet-tails with the star ALGOL
in the middle of them!!
The observations were made one year apart, but both at 10 apr. 21.00U.T.!
More info on my sketches! I hope you all enjoy the observations.
Both sketches were made with waterbased color- crayons on black paper.
Loc.: Trondheim, Norway.
Thank you for comments, and have a nice time under the stars!

Best from Per-Jonny Bremseth.
