Arp 134 is a galaxy very familiar to amateur astronomers being it is one of the biggest and brightest galaxies in the sky and looks perfectly normal to the eye and in most photos. I'm talking about the giant elliptical galaxy M49. So why would a perfectly normal elliptical make the list? Seems it is eating its companion UGC 07636, or so it appears. It is in Arp's classification as "Elliptical or elliptical like galaxies; with nearby fragments. UGC 07636 is the fragment. Apparently he thought it part of M49 rather than an appetizer. In my shot it is the blue splat like feature on the "front" of M49. Looks to me like where a blue phaser is hitting the Enterprise's shields and the energy is being spread across the shields. Notice the blue stars ripped from the galaxy spreading into M 49 or at least appearing to do so. In a black and white photo like you normally see this contrast is lost.
Look in the outskirts of M49's halo in the 1 o'clock position. There's an obvious galaxy being seen right through the halo stars. It is rather reddened by inter galactic dust. M49 has little or none so it isn't the cause. This is usually a sign of extreme distance. Sloan designates it as SDSS J122939.20+080229.1 and puts its red shift distance at 1.839 billion light years! That is one huge galaxy if we could see it at M49's distance of 60-70 million light years.
There are a lot of other NGC galaxies in the image. Considering we are looking in the heart of the Virgo Cluster this isn't surprising. NGC 4464 (E3) is at the top of the image a bit right of center. NGC 4465 (Sc) is much nearer Arp 134 on the very edge of its halo at 2 o'clock, just under a small blue star. It is rather small with little detail as it is 5 or 6 times farther away at 351 million light years and thus not a member of the Virgo cluster. NGC 4467 (E2) is even closer to Arp 134 and thus within the fainter outer halo at the 3 o'clock position just left of a rather bright blue star. NGC 4471 (E?) is in the halo at the 5 o'clock position. At the very bottom of my image barely left of NGC 4471 is NGC 4470 (Sa?) It's red shift is higher than what you'd expect for a Virgo cluster member but it is considered to be a member just the same. Notice how all these members of the cluster are far smaller that M49. That's because M49 is a giant among galaxies and one of the anchor galaxies whose gravity holds the cluster together (along with the dark matter of course). One other NGC galaxy is trying to get into the image. You see the western side of its halo at the far left. Normally it is a star on the edge of my CCD that is making a glaring entrance to the image. Here we just see the outer halo of NGC 4492, most of which is out of the frame. So this time the "glare" is real not just a reflection.
The spiral galaxy in the lower right corner is CGCG 042-125 (Sb(r)) It isn't a cluster member being at 335 million light years and thus likely in a group with NGC 4465 mentioned earlier. Nearer to Arp 134 almost on a line to its core from CGCG 042-125 is the weirdly named VIII Zw 189 (E0) and it is a member of the cluster.
The raw files picked up three very faint asteroids, one of which was first seen only a week or so before I took this image. They needed data on it a week after I took the image but I didn't look at my data until weeks after it was taken. Even the other two were so faint they didn't survive the JPG process, all being well below magnitude 20.5.
Arp's 200" photo of this galaxy is at:
It has south up rather than north up as for my photo. UGC 7636 is at the upper right in his blue light image of the system. Since the halo is rather lacking in blue light it barely shows in his image but UGC 7636 being very blue shows strongly. A color CCD image gives a more more natural look at the situation than does a film image taken in one color.
