All Messier Globular Clusters to scale

[sdbodin]

Final installment of the Messier tour with the Rokinon 135mm telephoto, the Globular Clusters. Not the best subjects for 135mm focal length, but doable. So, you might notice a hole for M68, but I can't wait to April to just to add a small smudge to finish, will sneak it in next spring. All the rest are over in my Messier Gallery, all 109 Rokinon shots to date and all to scale. Just hit the full screen option to get the scale right. All images here are short, between 10 and 30 minutes in 1 minute subs at f2 or f2.8 with the Asi1600MC-cool camera. I find the relative sizes of all the Messiers interesting, some like M57 microscopic and M44 mega huge. Final thoughts, don't need a telescope to see all the M's, just a camera and a telephoto lens.

Clear skies, happy M hunting,
Steve

Ok.....now that is just cool. Is it ok if i took a screenshot of that?

[Bigzmey]

Nicely done! It does put things in perspective.

Just right click and open the full size tab and save. Not against forum rules, I guess, and OK with me.

Very cool. I had no idea that M5 competed so closely with M13.
I know it's not a Messier target but I would be curious to see how this group compares next to Omega Centauri!

Interesting, but unfortunately Omega is below my horizon. But, my recollections from trips to southern climes, would have Omega at least double in size. As regards to M5/13, don't know if my mish-mash of exposures and unorganized processing distorted some of the images final presentation, all I know is one pixel exposed equals one pixel printed.

Just noticed!!! Where is M4??? well it is well and still in my M4 folder. Attached correction with missing M attached. Someone will have to check my slopy work and see if I missed any more.

Correction noted,

That is an impressive piece of work Steve. Fascinating to see them all side by side to compare.

Thanks, i will wait til you get M4 added

Found this comparison of Omega C and M13.....good grief Omega C is huge. I can't see it from my location but i am told that it is a naked eye object

Here is a link comparing Omega C to other globular clusters and shows the size difference as well.

Cool! Thanks for that link. I'm not able to see Omega C naked eye but that's only because it hovers about 8-10° above the horizon at its maximum height here in Las Vegas. Maybe Joe or someone else from down under can chime in and tell us if they can see it naked eye?

I can see it naked eye from SoCal.

Now i thought you would be able to see it that far south.

[jrkirkham]

Now that is interesting!

[Thefatkitty]

Steve, that is really well done, good for you on pulling that off! A great reference, and good luck with M68 next April. Astronomy teaches us patience

All the best,

Well, I have picked it up easily in 10x80 binos and I've imaged it but floating a mere 8-10° above the horizon it is not visible naked eye.

Five degrees above the horizon, maybe 6 if I am lucky and i better be on a hill above the trees lol. I believe May or June would be my best bet.

Edit ....So after consultations with sky safari it appears that the highes it gets in my sky will be June 6th 2025 at 2200. Its close enough to call it due south at 180 degrees azimuth and some short change and 6 degrees 48 minutes about the horizon. That is seriously in the soup.

Thanks all for reviewing the Messier Glob page, link to all the Rokinon pages can be found below:

app.php/gallery/album/210

All Rokinon shots are to the same scale app. 5.5 "/pixel, all are a crop from the full frame and all are less than a hour exposure, most under a half hour.

This project was fun, but not regimented, no uniform f stop, exposure length, or processing method, sooo... taking too much away as to brightness or extended size might be misleading , after all, we a amateurs we're in this for the fun.

Absolutely!
