I think you are off one digit on the NGC.

There's a little more to the story, though. The description of the "Splinter Galaxy" (NGC 5907) with Lord Rosse's 72-inch telescope in 1860 mentions "south preceding the nucleus there is a dark space with very faint nebulosity beyond".
Not knowing whether this was a separate object, Dreyer catalogued this "very faint nebulosity" as NGC 5906. But the sketch made by the observer using the 72-inch clearly shows this nebulosity is just the dim portion of the galaxy on the west side of the dust lane. So, NGC 5906 is actually part of the Splinter Galaxy.

Never seen this one. What can I expect to find in the eyepiece?

Hi Olivier,
NGC 5907 ( link ) is a wonderful target for moderate aperture under a dark sky. In my old 10 inch, this needle-thin edge-on covered a 12' by 1' area. It's among the most elongated galaxies you'll ever see.

Steve,
I stand corrected. You know, I thought it was suspect and that on some ground there might be this exception as nyte is pretty well seasoned. Ive misnumbered objects before so I figured... ok...
lo and behold my fears were realized and there is validity to the "6" digit.
wow.
Thanks for the input Steve

Bill,
It s amazing how many people at a star party simply never heard of this object - and I mean some with big scopes.
At any rate through my 8 its this terrific span of light.
Its like a best kept secret in a way.

Nice photo!
My May 31, 2009 observation: "Long, dim slash. Very narrow. Best @ 114x-133x. Mottling seen?" It's also on my look-at- again list.

I agree with that one. Last time I was in a star party, I was very surprised that even amateurs with decades of years of observing had no clue that there was such a little gem on the sky. Anyhow, here's my sketch done with my 12" scope. (Btw, it was seen without problems in a 6" scope on a sky about nelm 6.)

I'd forgotten completely about this, very glad it came up. I was looking for it in my 6" just before going off to college. Just saw it (and M102) 5 minutes ago in my 14.5" - closes out a 30 year gap for me. Just before the moon rose and the remains of a typhoon slam into California on Monday(!).
It looks so unreal - like a thread of yarn stretched across the sky.

Description from my 8" SCT from 1995:
v.long oval, edge-on, brite, round brite core, spindle of even briteness, diffuse edges, ends appear to flare slightly, nice.
With the 12.5", I added mottling along a center line and a possible dark lane, but harder to see than the dark lane in NGC891.
Here's a deep photo:

As with the Magellanic Clouds around the Milky Way, the tidal interaction of a large galaxy with satellites results in their being torn apart to form merely a stream of stars and gas going around the larger galaxy.
What you see is the remanant(s) of one or more satellite galaxies being eaten by the larger one. A similar photo of the Milky Way would expose similar streams for the Magellanic Clouds, though they are still somewhat more intact than the unfortunate satellites of NGC5907.
Note that the ends of 5907 appear warped in opposite directions. This is common when there are close tidal interactions. M31 displays the same thing. And a lot of other edge-ons do too.
Here's an image of NGC4565 that displays a similar warp to the disc:
4565
Now the warp in 4565 is thought to be the final oscillations of the disk after it's swallowed a smaller galaxy.
You can also see the core of 4565 is somewhat "peanut" shaped, which implies there is a small bar in the core. Nearly every edge-one that displays this peanut shaped core seems to have the same sort of rotational anomalies that helped identify the Milky Way as a barred spiral.
It's thought that all spirals oscillate back and forth between bars and grand spiral patterns over time (Francoise Combes of Paris Observatory, Scientific American Oct. 2005).
With time, we will identify all the in-between patterns as computer generated galaxies improve and more closely resemble what we see.

From notes w/10" SCT--what struck me about this galaxy was that it was in such a rich starfield and very thin. Object went on my Best of NGC list.

Is there just way more exposure time that lets this be seen in the photo ? I've not seen this before in other photos of the same galaxy .

Well,
It requires astounding abilities in the image-processing field.
