The DSLR god is angry at that comment, Min.
"There remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking." ~Christopher Hitchens, god is not Great

I really wish there was an accessible, physical way to understand the sizes of these things.

Two other objects are within this designation but not officially included:
Snowflake Cluster
and the Fox Fur Nebula
All of the objects are located in the Monoceros constellation and are located about 800 parsecs or 2600 light-years from Earth.
The field of view of my imaging set up is FOV= 50.7 x 76.1 arcmin, so with 1,000mm focal length, the object fills my field of view. What this means is that at this distance, the object is very big.

You got me curious. Not sure this will help.
The Cone Nebula is just the brighter part of the entire nebula and is estimated at 40 l.y. across (the entire emission nebula is about 190 l.y. across). This means that just the Cone Nebula is 9.5 times longer across than it is from the Earth to Proxima Centauri. Put another way it is 2.5 million times longer than the distance between the sun and the Earth. If my calculation is correct the Cone Nebula is 232,000,000,000,000 miles across.

To give you a relative size of this fov of my telescope, I can just barley get the entire Orion nebula (M42) in my field of view at prime focus, and it is 1,500 light years away. The same is true of the cone/foxfur nebula, that is, I can just get it in my field of view, even though it is 1,100 light years further away than the Orion nebula is.

Another comparison (although it just shifts the issue from unfathomable sizes to unfathomable quantities): if my calculations are correct, in a 40 light-year by 40 light-year by 40 light-year cube of space, one could tile - equator to equator and pole to pole - 43,500,000 moles of Earths.
Unrelated to anything except calculating large numbers, my favorite statistic of all time:
1) The main source of silk is the larva of Bombyx mori, the domesticated silkworm.
2) 10,000,000,000 (ten billion) pounds of silkworm cocoons are harvested a year.
3) 2,000 to 3,000 cocoons are needed to make a pound. Thus, the annual harvest is approximately 2.5 trillion cocoons.
4) Each cocoon consists of a strand of silk 300 to 900 meters long. If we average, that's 1,500,000,000,000,000 1.5 quadrillion meters of silk each year.
5) A light-year is 9,460,700,000,000,000 meters.
This means that silk worms produce .159 light-years of silk each year, or a light-year of silk every 6.31 years.
5)

Don't worry, my friend. If this be the end, then so shall it be.

According to DeepSky Stacker, the uncropped image (the first one) contains 5,546 stars. If each star has 4 planets, there would be 22,184 planets in that image.
