Globular galore
#2440794 - 06/05/08 05:29 AM

Winter is for open clusters, Spring is for galaxies, and Summer is for ... GLOBULARS!

Here are the globulars I've sketched the last few days in Oph and Her (and an older sketch from Com):

M10 (quite homogeneous globular in Ophiuchus, close to M12)

M12 (bit smaller than M10 but looks brighter with higher diversity of color and luminosity of its stars)

M13 (perhaps the most famous globular, found in Hercules, looks like a turtle)

M53 (this one is in Coma Berenices, quite bright and beautiful)

M92 (also in Hercules, very bright core area, splits well)

NGC 6229 (actually, Herschel catalogued this one as a planetary nebula, very faint and also in Hercules.)

M53 and NGC 6229 are drawn at 167x, the rest at 71x.

Larger originals can be found on the link in my footer.

And feel free to hijack this thread with your globular sketches

Great collection of gc sketches, Ferenc! You've really captured the unique features of each one. The large versions at your site really show how well-crafted your drawings are too. Thanks for sharing those.

Beautiful work, Ferenc!

It's interesting to see them side by side with different features.

Nice stash of sketches!
Too bad you didn't use higher magnification. Globular clusters can take magnification very well.

Thank you all for your kind words!

Vedran, I could have used higher magnification, you're right, but my primary aim was to take an overall look how the globulars look compared to their environment, and to stay comparable to eachother. I've however observed them with various magnification levels of course, as sketching is just a phase of the observation.

Nice sketches, Ferenc. Globs are some of my favorites.

I can't wait to do some more, but we're in the period of unending light up here for the next couple of months.

Great sketches! Really nice detail in them. I like the description of M13 as a turtle. I'll have to go look for that tonight.

Cheers

Ferenc,

An excellent series of globular cluster observations. You have captured the unique appearance of these globulars very nicely. Thank you for sharing them with us all.

Jeff- Very nice observations of M3 and M15. Thank you for sharing them with us all.

Good stuff. But where is M22. I get lost in M22 from my dark sky site with my 20" Obsession. Whadda sight! I got to get up there again tonight.

Thanks for starting this thread Ferenc, with some very nice sketches. Here's my rendition of M12.

Two more:

M3 (large, shiny, with a little bright ribbon to the East) (big one)

NGC 5466 (close to M3, maybe too close, so this one is not on the list for too many, even if it has similar size (but much fainter)) (big one)

Excellant sketches everyone, i like how you folks show latger aperture resolving more stars, sketches show this better than photos.

Ferenc,

These sketches like your others before them are most impressive.

I find NGC 5466 a tough target on nights that are not pristine from my poor location.

jeff in irelad- are you doing any kind of digital work on these glob sketches afterwards? they are so subtle and beautiful... what pencils are you using?

Here I go, thinking, wow Globs would be quite fun to do as a project.

Then Jeff posts a few of his and I'm all

Don't know if I could I capture them the way he has or the way the OP has.

I may have to target them as a subject for my next month's activities (should my skies cooperate).

Great job all.

Nothing digital other than inverting. (I've been known to make some of my stars rounder after scanning if I was sloppy when sketching, but globs are intricate enough that I'm not usually sloppy with them.)

First I place 100 - 150 stars using a Daler-Rowney Artist's Graphic HB pencil. (I don't think the type is that important, but I have noticed that the hardness scales between manufacturers don't line up very well.)

Then I add the "milky" background using the same pencil and a blending stump.

Lastly I stipple in stars using a 4H or 6H pencil. These stars aren't a 1:1 match with ones in the eyepiece -- I'm just trying to duplicate the brightness gradient that I see. For these I hold the pencil vertical and twirl it -- about 1/2 a rotation in the outer regions and perhaps 2 or 3 rotations in the core.

Thanks for the comments, everyone!

Cheers,
-- Jeff.

Three more faint globulars from the Ophiuchus & Serpens area to add, they are all very faint and tiny:

NGC 6535 (Found in Serpens Cauda, I believe this one could be resolved on a night with better seeing. Onion-shaped core.)

NGC 6517 (Ophiuchus, looks elongated in the N-S direction. Unresolvable.)

NGC 6539 (Ophiuchus. Very faint, perfectly symmetrical and is a pain to find.)

Observation data can be found here.

Ferenc,

Thank you for the additional observations of globular clusters. They all depict the clusters very nicely in the eyepiece.
