This time of year the sun never drops low enough under the horizon for
true astronomical darkness. Only after midnight we get a few hours of
relatively dark skies, but a faint blue glow always remains visible
above the northern horizon. However, bright objects can still be very
impressive in the eyepiece. Messier 5 is a fine example: a very bright
ball of stars, loosely scattered amidst a few dozen foreground stars.
When I made this sketch, the sun was only 12 degrees below the horizon.
What is very striking visually is the off-center core of M5. The
brightest part seems to be slightly to the west of the cluster.
I made the sketch using a white gel pen for the stars and a white soft
pastel pencil for the glow of unresolved stars. It was the first time I
made a positive deepsky sketch, normally I use graphite on white paper.
The image is the original field sketch.
Clear skies!

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.

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.

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!

Hello all,
I finally got to go bush with my latest scope acquisition, and my smallest scope, a 4” achro refractor. I was spoilt for choice for potential targets, but I settled on one target I’ve sketched four times previously, Eta Carina. The previous sketches of Eta Carina were done with an 8” (once) and my 17.5” (twice) and once with my binos from my home. But this time, I had the opportunity to chase the full extent of the visible nebulosity of this celestial giant. With the single eyepiece I took on this outing, this little refractor gives me a whopping TFOV of 5°! This would be the perfect weapon and dark sky combination to tackle this target.
Oh my goodness! How much detail is visible! At first glance the nebulosity is nice and compact. As the sketch developed, and I slowly examined the scene, the nebulosity kept on reaching further and further out. Add to this the mottling of the background Milky Way star field that surrounds Eta Carina. I also spotted a couple of faint open clusters in the field of view.
The sketch doesn’t show the full extent of the TFOV – the sheet of paper wasn’t big enough! I was spent after this too.
I hope you find this sketch to your liking.
Alex.

Unable to sleep I decided to get up early on October 29th. It was 5:00 in the morning and the air was crisp but the sight was absolutely gorgeous. I decided to get my pastels and try my best to represent the ambiance and colors of the scenery. Mars was at the left side of a crescent moon and Jupiter hanging high at the right hand side with Castor and Pollux (Gem)

My family went to international trip to Cebu, Philippines.
The Cebu’s latitude is N 10.2Ë™.
So I prepared 8inch travle dob (Uti 8) and observed deep sky in the resort beach.
The weather of Southest Asia is very changeable in the midnight.
For 3 nights, I drew a only one cluster! It located bottom of Scorpious.

Hi All. M67 has many nebulosity in the cluster.
And M67 is one of the oldest cluster in the sky.
I give a guess that is related to nebulosity…? I don’t know exactly 🙂

Hi all,
I’ve been itching to have a go again at Alphonsus for some time. Along with its two buddies, Arzachel (to left) and Ptolemaeus (at right), this trio are a time line of Lunar history.
Ptolemaeus is the oldest. The crater floor is totally flooded, even the central peak is covered. It was fromed when the Moon was still very hot and lava readily flowed with a large impact.
Arzachel is the youngest. The crater floor is intact with no flooding, the crater walls are terraced with land slides both inside and outside of the crater.
Alphonsus sits bewteen the two in age. The crater floor is only partially flooded with the central peak still visible. The Moon has cooled since Ptolemaeus and lava flow has slowed. BUT, volcanic activity was still occuring after the flooding process had stopped. This is seen from the pyroclastic deposits that sit within Alphonsus. Four deposits lie within this crater and are marked in the labelled pic, and are seen as the darker shaded areas that are easy to see through the eyepiece.
Quite remarkable to consider that from here on Earth we can see the effects of ancient volcanism on a body that isn’t Earth.
Another treasure of the night was the Celestron Ultima LX 8mm eyepiece I used. These eyepiece are much underrated, but are surprisingly good. The 8mm in particular is easy to use for extended viewing. It made the 2.5 hours much more bearable, and my eyes were not as fatigued as they have been after with other sketches that have taken less time to do. It’s one of my favourite eyepieces.
