This was the first sketch I completed at Astrofest in Queensland, Australia. I’ve been wanting to sketch this beautiful dark nebula ever since I first laid eye on it some three years ago. This dark nebula, B86, goes by the popular name of “The Ink Spot”. It sits smack bang in the centre of the densest star cloud in the whole sky, the Cloud of Sagittarius. And what sets it off even more is B86 has a gorgeous bright open cluster right next to it, NGC 6570. Both objects are more-or-less the same size as each other, even though both are not very large themselves. But it is the juxtaposition of these two very different objects against the blaze of the Milky Way that makes this pair a spectacular pairing.
Dark nebulae are clouds of dust and gas that are drifting through the Milky Way galaxy. Many of these conglomerations of dust and gas do end up being formed into stars and planets, but most just end up forming the fabric of the galaxy. In fact, the stars that we see actually only form a small percentage of the actual mass of galaxies. By far the greatest amount of a galaxy’s mass comes from this very dust and gas. The Ink Spot is a small patch of cloud. It is a very opaque nebula too. Dark nebulae are categorised according to their opacity, or how dark they are. The scale of opacity goes from 1 (very tenuous) through to 6 (very opaque). While the opacity of The Ink Spot may be a 5, it is because that it sits in the Cloud of Sagittarius that makes is a striking object.
The little open cluster NGC 6520 really works very well in setting off B86. Open clusters are groupings of stars that are all related to each other having been formed out of the same parent cloud of gas and dust. Evidence for this is seen in the spectra of the stars displaying the same chemical make up. The brothers and sisters of our own Sun have been identified this way, with the same chemical signature as our Sun having been identified in several close by stars even though the Sun’s ‘siblings’ have long drifted off away from each other. Open clusters are loose groupings, so even though they formed from the same source, their gravitational connection to each other is not strong enough to keep the group together for too long.
For me, this tiny patch of sky is one of my most favourite. Tiny and oh so precious. Brilliant, dark, stark, ghostly. All in one. Gorgeous.

For the first time I send you one of my sketches. I sketched the Pipe Nebula a month ago at Hakos Guestfarm / Namibia. It’s the first finished of about 20 sketches I did during 6 nights.
Object Name: Pipe Nebula (made of lots of Barnard Dark Nebulae)
Object type: Dark Nebula
Location: Hakos Guestfarm, Namib Naukluft, Namibia
Date: June 2nd and 3rd, 2014 (two nights, about 4 hours total of sketching while nebula passed zenith)
Media: Pastel and graphite pencils
Optics: Fujinon 25×150 Binoculars
Field is about 7 degrees wide.To concentrate on object (and not on dimensions) I used a pattern of stars printed from Guide 9. Sketch is processed with Photshop to change appearance from Grey/White to Black/Grey. Pinpoint stars and Globular Clusters added by Photoshop (to replace printed and sketched stars)
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.

Hi ASOD! This time I’ve drawn the incredible Homunculus and the surrounding nebula along with the stars. As a beginner, the sketch was a challenge for me. I`m not sure if the Keyhole and Carina nebula are 100% correct because of the light from early summer sunrise. Anyway, the Homunculus was amazing with interior dust lanes and notches.
