Hi ASOD community, ships this globular cluster of this last observation. This provides for cluster not be brilliant, but it is very nice in a dark sky, you can solve some timid stars inside. The nucleus is large, has a lot of intensity in comparison with the rest of cluster light but does see clearly, averted vision helps to solve all these details mentioned. Even for a small scope makes a treat for your senses.

Best Regards.

Messier 5 Globular Cluster
Messier 5 Globular Cluster

Object Name: Messier 5
Object Type: Globular cluster
Location: Deventer, The Netherlands
Date: June 2, 2014
Media: White pastel and white gel pen on black paper

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!

Light vs dark – The Jewel Box and The Coal Sack

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: IC 4756
Type: Open cluster
Date 9/16/2012
Instrument: 6″ F/5 dobsonian reflector
Sketch: Pencil on paper and then inverted after scanning into the computer.

This is a sketch of open cluster IC 4756 in Serpens made on September 16, 2012 with a 6″ F/5 dobsonian reflector. Very large cluster of stars near the pretty double Theta Serpentis. Some 30 – 50 stars were counted in the cluster which appears to have several concentrations of stars separated from one another by voids. the cluster fills the field at 75X.
