Enjoy ๐
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.

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
On two nights with more better seeing and sunlight angle or libration , I could see these views.
See below 2nd sketch over on the lunar horizon as the border with a line of the imaginary inner rim wall of this 130km diameter crater a bluish 10 mignitude permanent star was being moved on from over the Pythagoras to the Anaxagoras (Pilalous) in 4 minutes, …. that I think means moon and earth twin bodies each was(are) rotating and revolving.
It was thrilling to gaze and feel this massive giant old rocky ball goes ahead swinging or pitching his body in space.

I finally got to go bush with my latest scope acquisition, and my smallest scope, a 4โ achro refractor. I was spoilt for choice for potential targets, but I settled on one target Iโve sketched four times previously, Eta Carina. The previous sketches of Eta Carina were done with an 8โ (once) and my 17.5โ (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 5ยฐ! 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 doesnโt show the full extent of the TFOV โ the sheet of paper wasnโt big enough! I was spent after this too.
I hope you find this sketch to your liking.
Alex.

โ DEC, 16th, 2013. The transparency is bad in fog mist.
Instead, the air is warm, not cold….
Then, I have pick up a pencil to draw briefly in 30 minutes the glittering mountains central peak of Pythagoras crater.
