Hey ASOD!
I send this time a most interesting nebula for amateur-astronomers,
the light- variable Hubbles nebula! Info on my sketch.
The observation was made from Trondheim, Norway.
I used color-crayons on black paper.
Have a good time and dark sky from Per-Jonny Bremseth.
N.B. : In Norway it is summer, and the sky is light, so nothing to see of stars!
Hey ASOD!
I send the pencil-thin galaxy N.G.C. 4565.
It is a very interesting object on the northern sky!
I have more info on my sketch.
I used color-crayons (waterbased) on black paper.
Loc. : Trondheim, Norway.
Best wishes from Per-Jonny Bremseth.
Hello all,
A couple of weekends ago saw Ice In Space Astro Camp ’14 happen at Lostock in rural NSW, Australia. I arrived late on the Friday, and when I finally settled at the camp it was dark and I just didn’t feel like setting up a big scope. The sky was clear, the full brilliance of the Milky Way was arcing overhead, so it was a great chance for some wide field sketching with my little 4″ achro.
Some time ago I had made a mental note of a potential sketching target as being the area around the lovely cluster The Jewel Box in the Southern Cross. The great thing about this scope and eyepiece combination is the true field of view encompasses the Jewel Box, Mimosa or Beta Cruxius, and the western edge of the dark nebula The Coal Sack, all set off against the mottled background Milky Way. Gorgeous stuff!
The Coal Sack is also surprisingly detailed. Streamers of darker lines, patches of brighter, and ghostly arcs. These details made for a great challenge as they are, well, black… Another fainter open cluster can also be seen just to the upper right of the Jewel Box. The Southern Cross contains dozens of open clusters within its boarder.
This sketch is very close to showing the full 5deg True Field of View I had.
Object: Jewel Box and the Coal Sack.
Scope: 4″ f/5 achromatic refractor
Gear: 30mm 82deg Explore Scientific, 17X, 5deg TFOV.
Location: Lostock, NSW, Oz
Date: 25th April, 2014
Media: White soft pastel, charcoal and white ink on A4 size black paper.
Duration: approx. 2hrs
Lunar Terminator Near to the Western Limb
On Sunday evening I was getting a wonderful view of the lunar terminator near the western limb just a half day before full Moon. The favorable longitudinal libration of -04° 40’ was creating an opportunity to see craters along the terminator that are often poorly placed for viewing.
With storms on the way from the southwest this was a good evening to attempt a sketch. The calm before the arrival of storms often leaves the seeing fair to good as was the case on this night. Craters such as Vasco da Gama (99 km.), Bohr (73 km.), Dalton (63 km.), Balboa (71 km.) and part of Einstein (175 km.) were all seen. Craters Cardanus (51 km.) and Krafft (53 km.) and the crater chain (catena) between them were in bright sunlight. The views all along the terminator were magnificent.
Sketching:
For this sketch I used: black Strathmore 400 Artagain paper (9” x 12”), white and black Conte’
pastel pencils. In addition a small artist’s brush and powdered Conte’ white crayon was used for blending. Contrast was slightly increased (+2) using a scanner to better match the original.
Telescope: 13.1 inch f/ 5.9 Dobsonian and 6 mm eyepiece 327 X
Date: 02-25-2013, 04:00-06:30 UT
Temperature: 0.0° C (32° F)
Partly cloudy, calm

Hey ASOD!
I send you an old sketch of a occultation of Saturn by the moon!
This is the most interesting occultation of Saturn I have seen.
The rings were wide open and the sky was clean.
I used a stop- clock for the timing of this event. Info on the sketch!
For my sketch, I used color crayons on black paper.
Location: Trondheim, Norway.
Best wishes and clear sky from Per-Jonny Bremseth.
Thanks for nice comments!
Hey ASOD!
This time I send you my observation of the wellknown planetary M. 57 in Lyra.
The centralstar was not seen in my telescope, but the ring is allways beautiful to see!
The west and the eastern “ends” of the ring was more diffuse, and the northern
part of the ring brighter and sharper. Info on my sketch.
The sketch was made with watercolor crayons on black paper.
Location: Trondheim, Norway.
Best wishes from Per-Jonny Bremseth.
Made this sketch of crater Lambert, Mons La Hire and Dorsum Zirkel and surrounding areas this evening, using my 505mm mirror and Watec video camera on its least sensitive setting. The view on the monitor was delightful and one I shared with optical designer and engineer Mr Es Reid of Cambridge, all very civilized and enjoyable.
The sketch was made on black A5 220gm art paper using Conte hard pastels and acrylic paint for bright highlights and deep shadow.
I hope you like it.
Kind regards, Dale

Hey ASOD!
This time I send again a sketch of the unforgetable great comet Hale-Bopp!
The observation was made the time before the fine spiral-bows appeared.
There was a bay of almost dark sky between the two tails.
C/ Hale-Bopp was the finest comet I have seen, and longlasting on the northern sky,
with many fine structures to observe in the inner coma.
I used color-crayons on black paper. Info on my sketch.
Location: Trondheim, Norway.
This year I celebrate 50 years as an amateur-astronomer (65 years old),
and have 330 sketches total!
Thank you for your comments and HAPPY NEW YEAR
from Per-Jonny Bremseth.
I saw SN2014J in M82 on Korean New Year night.
It is very surprise event to me, since I’ve never seen bright supernova.
Already I saw some supernovas in 2011. (M51, M101, NGC2655)
But that is more dark than this one.
I feel some futility.. because it is too easy to observing 🙂
I drew a sketch with 10″ dob, black paper and white pastel & jelly pen.
And I compared with my previous M82 sketch.
It is so interesting, I want to share everyone!
(original sketch : http://www.nightflight.or.kr/xe/files/attach/images/25489/716/121/453c7cb7b53fccfc7ac22288b35e05ed.jpg)
I’ve been doing a study on lunar phases and this is my latest sketch. This is a photo of it from last night after wrapping up my observing session. No adjustments have been made to the sketch other than cropping the lower blank portion of the paper.
My phase sketches used to take close to two hours to complete at the eyepiece. I’ve been building up my endurance to 3-4 hours for a single sketch to include more detail. Obviously, the terminator is drawn first to “freeze” the time stamp on the phase. Then I work my way across the disk at a more leisurely pace, moving my observing chair and stool gradually as the session progresses.
I used a 102mm f/9.8 refractor on an LXD75 mount, 20mm eyepiece setting on my Hyperion zoom, and a 13% T Moon filter to help with contrast. The media is black Strathmore Artagain paper (60 lb., 160 g/m2), white charcoal pencil, black charcoal pencil, white Conte’ crayon, white Conte’ pastel pencil, black Conte’ color pencil,and a blending stump for the maria. I used a circular 6-inch protractor to outline the lunar disk.
Total eyepiece/sketch time is just over four hours on this one.
