This is my first attempt at sketching a globular cluster, M 10. I used some of the past sketching tutorials to do this. Hopefully with time ( and clear weather ) I can experience a "learning curve".

Randolph,

I really like the 3D aspect to your sketch of M10. Good capture of the tendrils also.

Randolph,

This is an impressive sketch of M-10.
Globulars can be difficult to sketch but this sketch looks great.

Randolph,

I like this drawing a lot. I agree with Eric--it has a 3D quality.

I'm curious about what media you used. Also, with the blue at the top and red at the bottom, is that chromatic aberration from your scope?

For this sketch I used graphite dust from and HB pencil and then applied with blending stumps to get the effect of the unresolved stars and general shape of the globular. I defocused the scope slightly at this point to try to capture the overall shape. I used 2H and 4H pencils to stipple the barely resolved stars. HB pencil for the brighter field stars and some of these are not as point like as I would have liked ( I've really just begun to sketch deep sky objects, did lunar sketches only ). I scanned the sketch and reversed it. Used Picasa to darken the background and honestly I can't account for the color difference from top to bottom. My eye certainly did not see this, and I wasn't too happy with it.

First time? Really?

I think you are pulling out leg!

Very good job. I really reminds me of looking at it in the eyepiece.

Really and truly first time sketching a globular. I had only done lunar ( many of these ) sketching. I used the tutorials that were posted here that I've saved. And oh do I have a hard time with using a dim red light. With lunar sketching I could almost use a reading lamp!

Randolph, your sketch looks like one of my first images. I am not kidding (well, I am kidding a little) - same artifacts on the stars and even the atmospheric dispersion...LOL. Love the 3D affect. Well done.

Randolph, I'm seriously impressed by this drawing. In fact, I think it's a good thing that you didn't correct the stars but left the original pencil marks, which are never 100% circular. This way the drawing actually looks a lot more realistic, as if seeing and high mag impaired the observation a bit. Very, very good!
