Consider what it is to be truly countless...quite a word. Here is a small field with many hundreds of galaxies each with hundreds of billions of suns with severalfold that many planets:
Then consider outside of this field—just a small move—are more, and there are more beyond the reach of this instrument. Perhaps for the first time this field has been captured in color at this depth. Although nothing is countless here- it sure feels pretty close.
Of course, you *must* click on the image to enlarge to appreciate what is hidden in this field.
The Helix Nebula is a nearby dying star whose fate perhaps mirrors our own sun many billions of years from now.
The intricate radial fingers with thin trailing streams of gas and dust are mesmerizing. Then look beyond, through the center, to infinity...
Although the name may seem inscrutable at first, this nebula looks much better than it sounds:

Here we have a dying sun whose outer layers form a glowing bubble midst a sea of stars. Its essence is both ethereal and mysterious as processes that make these forms are complex and not always well-understood. This particular one could be on the order of 3,000 light years away. With over 22 hours invested in exposure time, few pictures of this nebula exist which are this deep in full color. (see below)
Technical note: This could be one of the deepest images of this nebula ever taken using broadband (full color) filters. There exists a beautiful rendition of this nebula taken by ESO's VLT 8 meter telescope (ten times the size of the one I used) last year. However, their filter set does not sample the OIII emission (color) as having a blue component since the OIII line falls much more in the V filter. Whereas using the filter set at the 0.8m Schulman Telescope we capture the overlap of the green and blue color of this nebula better and render it closer to what eyeballs would see if it were brighter (which it isn't!).
Here is the collision of some very far away galaxies:
Like the more famous Whirlpool galaxy, the interloper to the left pulls and severely distorts the regular spiral galaxy. To my eye it appears that the nucleus of the main galaxy has been tugged so violently that it has been displaced from its former central location based on the persistent spiral pattern that remains!
This galaxy is more than 500 million light years away and it is a tiny 1 acrminute across. It is also one of the many discrepancies found in the NGC catalogue. I am labeling this object NGC 218 and PGC 2726 (the interloper) based on the most recent analysis I could find.
