Same-Scale DSO Collage

I assembled a collection of common DSO's that I have shot and created a collage in which all objects are at the exact same scale to each other as seen from Earth. This gives you a clear picture of how small and how large some objects are in the sky. I tossed in the moon as a comparison. Yes - M31 is really that big - and M57 is that small (if you even find it)!

The collage includes (left to right - top to bottom):

M42/43 (Orion nebula)
M101 (Galaxy in Ursa Major)
NGC 2024 (Flame Nebula)
Barnard 33 (Horsehead Nebula)
M20 (Trifed Nebula)
M45 (Pleiades Star Cluster)
M33 (Galaxy in Triangulum)
M17 (Omega/Swan Nebula)
M1 (Crab Nebula)
Luna
M57 (Ring Nebula)
M51 (Whirlpool Galaxy)
NGC 7635 (Bubble Nebula)
NGC 6207 (Galaxy in Hercules)
M13 (Globular Cluster in Hercules)
NGC 884 & NGC 869 (Double Cluster)
NGC 6888 (Crescent Nebula)
M27 (Dumbell Nebula)
M8 (Lagoon Nebula)
NGC 7293 (Helix Nebula)
M31 (Andromeda Galaxy)
M32 (Galaxy near Andromeda)

These are all film exposures of course, using Kodak Elite Chrome 200 and Fujichrome 400F Provia.
Clear skies to you!

Very interesting comparison and great shots.

Peter,

Your photo deserves to be sent to S&T for their monthly photo section. Very instructional.

Mark

Holy cow, what a great picture! Film exposures, what's that? I'm kidding of course. Fantastic! Pete

I have created a large 23" x 35" poster of this image.
Here's a low-res version to sample: http://www.cloudynights.com/photopost/data/500/9328Astro-poster_lr_.png

The poster is much larger, and higher resolution. Email me if you want a copy of the hi-res poster.

Enjoy!

Peter

Peter,

My poster has arrived and is at the framers. It will be up in my observatory in about a week. It is the best looking astro poster I have seen!
